How Molds Affect Citrus Crops

Blue and green mold are two of the most important post-harvest diseases that can affect a citrus crop. The infection that occurs the most frequently is green mold and it is caused by the mold Penicillium digitatum. It exists in all citrus fruit growing regions and is a serious threat to the citrus industry.

When the fruit is bruised or punctured while it is being harvested or packed, the mold enters the fruit through these wounds and therefore, this disease can be contracted by fruit on the tree, in the packinghouse where the fruit is prepared for the market, while in transit to the store, in storage, and the retail store. At first, only a white mold is seen growing on the outside of the fruit and later begins to turn green due to the large amount of spores that are being produced on the surface of the fruit. The fruit begins to decay and become soft. It shrivels up and dies as a result.

Blue mold is caused by the fungus Penicillium italicum and it is different from green mold mainly because of the color. The conditions that the two molds grow in are very similar and tend to grow best at around 75 degrees Fahrenheit. Their growth is slowed by lowering the temperature and cooling fruits while they are being stored and shipped are a good way to decrease the amount of infections in a shipment. Losses from these molds can also be greatly reduced by taking special care during harvesting and transporting not to bruise or break the skin of the fruits. Fruits mainly become infected when their outer skin is broken and mold spores make their way inside either from contaminated soil, another infected fruit, or through the air. Fungicides can also be used to reduce the amount of infections. Also, any equipment used to pack the fruit and anywhere they are stored should be sanitized every day to reduce the chance of the fruit becoming infected.

The spores of both of these molds are very easily spread by air currents and any fruits that are contaminated with them should not be exposed to wind or other currents of air near any healthy fruit due to the likelihood of it becoming infected. Fruits can also become infected due to other physical injuries such as those associated with stem-end rind breakdown and chilling injuries.

Gray Fruit Mold Causes Food And Fruit Rot

One of the most frequent and serious causes of fruit rot in strawberries, blackberries, and raspberries is gray mold. This can affect not only the fruit itself, but also the petals, fruit caps, and flower stalks. There is not another disease as serious as this one during a wet, warm growing season. This is the most extreme during the years that have a prolonged cloudy and rainy period during the fruit’s blooming season or harvest.

Young fruit blossoms are typically the most susceptible to the infection and they usually start to show infection in a cluster of fruit. Blossoms generally show the fruit infection as a soft, light brown, and quickly growing spot on the fruit. If it is let to remain attached to the plant, it will shrink, dry up, and become covered in a powdery, gray substance. This is where the disease gets the name of gray mold.

Fruit that are the most commonly affected are located toward the middle of the plant where the leaves and branches cause the humidity to be high and air circulation to be low. When strawberries rest upon the soil or when one strawberry touches an infected one or just a dead leaf, the fruit rot will begin.

Mature fruits are also susceptible after they are picked, but the younger green fruits may become just as infected; however, the disease isn’t usually detected until later when the fruit is ready to be harvested. Mature fruits are likely to be infected because of bruising or the breaking of the skin and if the conditions for the disease are favorable, mature fruits can become completely rotted as little as 48 hours after being picked.

To prevent gray mold from growing on your fruit, you should select a site to plant your fruit that has a good amount of soil drainage and air circulation. They should also be exposed to direct sunlight.

A good amount of straw mulch should be put between the plants to reduce the amount of contact the healthy fruit has with the soil.

Keep your fruit garden weeded, since it will slow the air movement in the canopy of the plant. Fruits need to be dry to reduce the chance of infection.

Remove any berries that have become diseased, but do not leave them in your garden. Take them away and make sure they do not come into contact with anything else you are growing.

Examples Of Mold Diseases That Most Never Heard Of

The names of diseases that are caused by mold typically end in the suffix “mycosis” and while you might not think that such diseases are that dangerous, but think again. These are serious illnesses that can lead to irreparable damage to different organs in your body and can even result in death in some extreme cases. Those at risk to contract them are generally those who have a weakened immune system, small children, the elderly, and anyone whose body is weak, such as a person who is undergoing chemotherapy or is recovering from a recent surgery. Mold contaminated surgical instruments can also transmit these diseases if they are not properly sterilized

Most of the diseases that are caused by mold begin with some flu-like symptoms like coughing, pain in the joints and muscles, fever, and chills. The medications used to treat these conditions can cause the very same symptoms that the disease does and can also end up causing some kidney, liver, skin, and eye damage if their usage is not monitored. Any doctor that prescribes such antifungal medication will probably require frequent lab work to be done on the patient to catch these side effects before they get out of hand.

Aspergillosis is a disease that are caused by molds belonging to the genus of Aspergillus and these molds are typically found not only outdoors, but can also be found indoors, as well. They have been known to produce what are called “aspergilloma” in any pre-existing cavity in the body such as those arising from cancer, cystic fibrosis, tuberculosis, or similar conditions. Aspergilloma often have no symptoms for quite a while, but when they do finally show themselves, they can include coughing up blood, weight loss, fever, and shortness of breath.

Another condition that commonly affects our pets (but can also affect humans) is called Blastomycosis. This disease can cause pneumonia and other kinds of respiratory infections in humans and animals and can spread to the rest of the body. When the mold spores enter the body, they become yeast and since yeast itself is not contagious, you should not worry about your pet giving it to you if they are showing signs of it. The cutaneous form of the disease shows itself as lesions on the skin of the body and if they are left moist and untreated, it can cause much damage to the surrounding bone and tissue.

These are only two of the diseases that can be caused by mold. There are others that are just as serious. If you suspect a mold infestation in your home, perform some do-it-yourself mold tests and have the results determined by a laboratory specializing in mold.

Most Are Unaware Of The Dreaded Diseases Caused By Mold

If you hear of an illness that ends in “mycosis”, it was probably caused by a mold. Those who are particularly at risk to contract this class of diseases are those with compromised immune systems and this often occurs in people who have a cancer of the blood, chemotherapy patients, those with HIV or AIDs, anyone with serious blood disorders. Even though these diseases are far more likely to affect those with compromised immune systems, they can develop after a person has surgery or any other invasive procedure. It can also be transmitted by contaminated surgical instruments.

Generally the first symptoms of these mycotic diseases are those that are similar to the flu, such as chills, coughing, pain in the muscles and the joints, and fever. Medications that are antifungal can cause some of these symptoms, as well, even though the fungal infection that it is intended to treat cause these exact same symptoms. These drugs can also cause kidney damage and end up affecting the eyes, skin, or liver and a doctor will probably ask for labwork often in order to catch some of these serious side effects before they become out of control.

Some of the diseases that can be caught from a mold are histoplasmosis, cryptococcosis, coccidioidomycosis, candidiasis, blastomycosis, and aspergillosis. These are serious fungal diseases and should be treated as such.

Aspergillosis is caused by molds in the Aspergillus genus and tends to be found in many places including buildings, plants, food, water, and soil.

Blastomycosis is caused by Blastomyces and is found soils that are rich in nutrients and very moist. It has been known to affect both animals and humans.

Candidiasis is caused from the mold Candida and can cause mouth infections or genital yeast infections, but it is even more serious when it ends up invading the bloodstream. Candida is found in the intestines naturally, however.

Coccidioidomycosis is caused by the mold coccidioides and this is found most often in the dry soil in the southwestern United States, and central and South America. It starts as a flu-like disease, but can infect the lungs and infect the other organs in the body, including the brain.

Cryptococcosis is caused by Cryptococcus and associated the most with Eucalyptus trees and bird droppings. It typically begins in the lungs, but has no symptoms until it spreads to the rest of the body.

Histoplasmosis is caused by Histoplasma and tends to infect the lungs. Like other fungal infections, it includes flu-like symptoms and can spread to the rest of the body.

Mold Fun Facts

Mold is everywhere around us. Be it indoors or outdoors. It is simply there. There is no such thing as a mold-free environment on this planet, or any other. There are three things that mold absolutely must have to survive. And the only time that mold is visible to the naked human eye is when large colonies begin to grow and gather. Previously stated was the fact that there are three things that mold need to survive.

First of all, mold requires nutrients. And if the mold was in an outdoor environment, these nutrients would most likely be acquired from organic matter like dead animals or dead plants. This is natural and necessary so that debris that builds up from the cadaver of the animal or plant. The mold causes decomposition and that helps the fertilization product in plants. The mold can also inhabit discarded trash such as cardboard, paper, pieces of drywall, fabrics, and other kinds of dust.

Another key element that is essential to the survival of mold is moisture. The decaying of organic matter requires moisture. As does the digesting of the organic matter by the mold. In fact, the highest numbers of cases of mold infestation occur during the summer time, when there is high humidity, and therefore higher condensation. This condensation gathers inside of a house. Winter time is also a bad time for homes, because certain areas can become drafty, and that can lead to condensation build up.

Something else that mold requires is something that there is an unlimited supply of. And that would be: time. Mold simply requires the time to grow. It can start a colony, after it has gained a sufficient amount of nutrients and moisture, in up to twenty four hours. And if something like a wet towel or piece of clothing is simply allowed to sit, then the mold is simply being handed enough time to gather in size and in number.

The last thing mold requires in order to survive and continue to spread is heat. Most molds do not even require an exponential amount of heat in order to spread. However, a good number of molds need it. Molds have been known to remain dormant at extreme temperatures while not growing. They stay in a kind of suspended animation. This goes for cold temperatures as well. They can be exposed to temperatures near two degrees Celsius, and they would revert to this state of suspended animation.

Refrigerator Cleanliness and Mold

Keeping a healthy and happy home is hard enough without having to deal with mold in your home and around your food. Most of us have enough problems with our kids and spouses eating healthy and having healthy lifestyles without having to worry about the mold that grows in our refrigerators. We are typically too busy to think about cleaning out our refrigerators most of the time, but this really needs to be done at least once every few months to discourage mold and mildew from residing in one of the most important appliances that we own.

Make sure that you know what things in your refrigerator need to be replaced. This includes items that are outdated or are obviously contaminated with mold. Depending on the item, it may or may not be able to be saved after mold starts to grow on it. In fact, most items in the refrigerator cannot be saved after mold begins to grow. This is usually because most items in our refrigerators are very moist and porous, which allows the mold to infect the entire container of food.

Very moist items are things like mayonnaise, sour cream, jellies, jams, and anything else that you can scoop out with a spoon. Unfortunately, not only moist items are affected heavily by mold. Porous items (items that are not very dense) are also heavily affected, such as meats and dairy products, such as individually sliced cheese or shredded cheese.

Any eggs in the refrigerator that are cracked before we intend to use them should be thrown away, since the shell is what protects the inside of the egg from bacteria.

Fruits and vegetables need to be checked for mold regularly and anything that has mold on it should be thrown away immediately before it has a chance to infect everything else around it. Clean out your fruit and vegetable drawers as often as you need to in order to keep the free of decaying matter like stray lettuce scraps.

Actually cleaning out the refrigerator is a time consuming task and can take a few hours. Begin by taking everything out of the refrigerator and setting it aside. Remove everything in the refrigerator that can be removed, such as shelves, drawers, and racks. Wash these in the sink with warm, soapy water if you can fit them there and allow them to dry. Wash every surface that cannot be removed and rinse it thoroughly. Replace all the items from the sink and go through all the food you took out to clear out the outdated items. Wash the bottoms of jars that have become sticky before putting them back

Prevention of Mold on Your Belongings

All kinds of things in your home can be affected by mold, but you can do quite a few things to protect them and restore them if you do a little research. A lot of molded items can be cleaned and saved, but there are a few that just have to be thrown away.

If mold gets on anything made of real leather it cannot be restored. Leather is a piece of porous organic material and mold decomposes items like this pretty quickly. It will discolor the leather and this discoloration cannot be repaired in 99 percent of cases.

Baby bottles come in strange shapes these days and are very often difficult to get completely dry. Water bottles and other beverage containers that we may have in our cabinets come in shapes just as strange and if you do not have a dishwasher with a dry cycle, it can be pretty hard to get these dry without a good amount of effort. The solution to this problem is to place these bottles in the freezer until you are ready to use them again. This prevents mold from growing on it, since mold does not grow in freezing temperatures.

Something else that causes mold to grow on your belongings, especially clothes, is the simple act of throwing wet clothing on the floor or into the back of the closet and forgetting about them. Most people do not wash wet clothes immediately; we tend to just throw them on the floor and then throw dry clothes on top of them. This usually causes the dry clothes to become moldy if we leave them there more than a day or two. Not only does it cause the clothes on top of them to become moldy, but if the wet items were thrown directly onto carpet, the carpet can become just as moldy. Once carpet is molded, it usually needs to be taken up and replaced, but the padding underneath always needs to be removed because it cannot be cleaned.

If you have a lot of clothes in your closet, maybe you need to make sure that you do not pack them into the closet so tight that the air cannot circulate. The clothes insulate each other and create warmth in the closet where mold can start growing after just a few days. Some closets come with vents installed to prevent this problem, but if yours does not, you should probably find another way to store your clothes or get rid of the ones that you do not use.

Hurricane, Flood, and Water Damage Tips

Mandatory evacuations during hurricanes and floods are not always fun to have to deal with and even during hurricane Katrina, some people did not wish to evacuate their homes and did not believe that they should be made to leave their property if they did not want to. If you cannot evacuate from your home for one reason or another or wish not to, then you really need to be prepared to stay there for a long period of time until the flood waters recede and the area is cleaned back up.

This means that you need to be stocked up with plenty of food and even more bottled water than you think you might need for a week or two’s time. Depending on the number of people in the home, you will want to have more food and water saved up. Having one gallon of water put up for each person for every day you expect to be staying in the home and even more than that, since you never know exactly when you will be able to leave.

If you need to leave the home for any reason and the waters have receded, something you need to be aware of is downed power lines. These are extremely dangerous and you can never tell if the downed line is electrified or not. Never attempt to cross one of these, not even in a vehicle.

Whatever water damage was inflicted on your home needs to be recorded with a camcorder, if you can get your hands on one. You can show this to your insurance claims adjuster so that he or she knows just how much damage was done to your home and can give you a good idea of how much compensation you can expect from your insurance company.

After you have made a video of the damage, drying out your home is the next thing that you need to start doing. Wet items should be taken outside and left to dry, unless more rain is expected.

Open the doors and windows all around the home so that air from outside can blow through out the structure and start drying things out naturally. A wet vacuum can be used to help extract some of the water from under hardwood floors, but a regular vacuum cleaner should never be used to do this due to the risk of electrocution.

How Water Affects Documents

Water damaged documents and books can be a pain for homeowners and especially libraries to have to deal with. If you are planning on salvaging papers or books, there are a few things that you need to know, especially if some of the things you may have to restore are very old or rare.

Most people are not aware of the fact that depending on the condition, composition of the paper, and the age of it, it will absorb more or less water than you would expect. If you have a large collection of old texts and you live in an area where water damage due to floods or hurricanes, knowing about how much water your collection will absorb will help you select a drying method that is appropriate. Information you also might want to have is just how long your particular collection can stay under water before some serious deterioration of the material occurs.

Some papers may absorb up to 200 percent of their original weight. Materials that are older than around the year 1840 can absorb up to around 80 percent of their weight and these old materials are particularly sensitive to mold when they have been immersed in water.

Most of the damage that occurs to books that is caused by the swelling of the materials will happen within around the first four hours after they have been submerged. The papers of the text block and the cardboard that the book binding may contain will soak up quite a lot of water and this will eventually cause the block of text to become either partially or completely detached from the binding and this is most noted when the material starts to dry out on its own and the humidity in the area falls below around 70 percent.

Most leather and vellum books can be saved if they are dried using some very carefully controlled measures. If the leather or vellum book that you are trying to salvage is from the 15th, 16th, or 17th century, you are probably already aware of the rarity of it, so these should not be mixed together with other materials for salvation, stabilization, or drying.

The most important thing to do before you start treating your papers is to stabilize the environment they are in. Lower the humidity to around 65 percent and get rid of any standing water that still exists. If you have a large amount of books that are packed onto bookshelves very tightly, they should not be removed and fanned out because this will help stop mold from growing on them, at least on the insides.
