Keep those gray fuzzy strawberries in check
Anthracnose fungus — Glomerella cingulata : The fungus which causes anthracnose attacks both the fruit and the foliage. Infected fruit are characterized by a soft rot and premature dropping of the fruit. Immature fruit are dried up and may remain on the tree. Infection results in a small, sunken, discolored area. The areas enlarge with age and become covered with a pink mass of spores. Affected leaves will have a dark brown margin. Defoliation occurs with increased infection.
Sanitation is extremely important in the fig planting. Diseased fruit as well as infected leaves should be removed. Dieback physiological — cold injury : Fig trees are often injured by early or late frosts that kill younger twigs. Although their death is not related directly to loss in production, they may serve as a site for secondary fungi to get started.
All dead twigs and limbs should be pruned from the trees. Fig Mosaic virus : Affected figs show large yellow areas in the leaves, oak leaf pattern, ring spot area, or a mild mottled pattern.
Leaves may be smaller than normal and deformed. Premature defoliation and fruit drop often occur. The virus is spread by vegetative cuttings and Aceria ficus eriophyid mite. Control is by selection of clean propagating stock and insect control. Fig Rust fungus — Physopella fici : The disease is first evident as small, angular, yellow-green flecks on the leaf. The spots do not become extremely large but do become more yellow and finally a yellowish-brown.
The margin of the spot is reddish in color. On the upper surface the spots are smooth, while on the lower surface the spots appear as small blisters.
Brown spores are released from the blisters at maturity. As infection continues, the leaves become more yellow, and finally they begin to die around the leaf margins. Eventually death and defoliation occur.
Complete defoliation can occur in two or three weeks. Fig rust generally becomes a problem as the fruit reaches maturity. Therefore, fungicide applications should be started in the early spring when the first leaves are completely grown.
Make additional applications as new growth is formed. Do not spray when the fruit is one-fourth inch in diameter as the spray residue will make the fruit unattractive. Resume spraying after the fruit has been harvested.
Fruit Drop physiological — flower development : The fig produces four types of flowers male, female, Gall, and Mule : The male and female flowers are most often associated with the Capri type fig. This fig requires a wasp for pollination.
The wasp does not occur in this part of the United States, thus it is impossible to grow Capri figs in Texas. Gall flowers are imperfect female flowers. They are found only on Capri and Cordelia figs. Mule flowers need no pollination and produce no seeds. The common fig grown in Texas produces primarily mule flowers. Since no seed are formed, the mule flowers are more subject to dropping than than those flowers which require pollination. The presence of the seed and the growth hormones produced by the seed help prevent fruit drop.
The figs grown in Texas due to absence of seed are more subject to premature fruit drop as a result of adverse growing conditions. Leaf Blight fungus — Pellicularia kolerga : In early stages of infection, small areas in the leaves become yellow and appear watersoaked. With continual development, the upper surface becomes silvery white, and the lower surface becomes light brown and covered with a thin fungal web. In most cases, the leaves will turn brown and shrivel.
It affects primarily the leaves but may develop on some fruit if it is new and a severely affected leaf or stem tip. Sanitation is the only recommendation to reduce losses from this disease. Limb Blight fungus — Corticum salmonicolor : Affected limbs wilt rapidly. The fungus enters at a spot along the main or secondary limbs, and all leaves die beyond that point.
The fungus enters at a dead fruiting spore or at some other injured spot. All dead twigs and limbs should be removed by pruning so that they will not serve as infection sites. Root Knot Nematodes nematode — Meloidogyne spp. Infected roots are characterized by small galls or swellings on the roots.
The presence of the galls on the roots interferes with the normal uptake of nutrients by the roots. Plants infested with root knot are stunted and have a general unhealthy appearance. Infested planting sites should be treated with Vapam prior to planting. This will reduce the nematodes in the soil to a low level. Do not use around living plants as it will result in severe root pruning, and in many cases death will occur.
Make sure the fig plant is free of root knot. Once planted, the only practice left is to keep the plant in good health with regular fertilizer applications and maintain adequate moisture around the plant. If nematodes were initially present, the fig will eventually become infested, but the root system should be well established by then.
See Section on Root Knot Nematodes. Sclerotium Blight fungus — Sclerotium rolfsii : A yellowish-white mat of fungal growth is formed at the base of the plant. Round, hard, yellowish to brown bodies sclerotia are found scattered in the fungal growth.
To prevent the occurrence of this disease, it is important to carry out a thorough sanitation program. Old leaves or grass around the base of tree will encourage fungal development. Souring several fungi and bacteria : Organisms are carried into the fruit by the dried fruit beetle. Some examples of closed eye figs are Celest, Texas Everbearing, and Alma. No chemical control has been found to be totally effective. Maneb fungicide will help to some extent.
Insects should be controlled to eliminate them as carriers for the disease causing organisms. Skip to content.

Sixty-four tree nut samples almonds, pecans, pine nuts, and walnuts and 50 dried fruit samples apricots, cranberries, papaya, pineapple, and raisins were purchased from local supermarkets and analyzed for fungal contamination using conventional culture as well as molecular methods. The results of our study showed that the highest yeast and mold YM counts 5. The most common mold in nuts was Aspergillus niger, relatively low numbers of A. Low levels 2. The highest fungal levels were present in raisins. All papaya samples and the majority of cranberry, pineapple, and apricot samples were free of live fungi. The most common mold in dried fruits was A. One apricot sample also contained low levels 2.

The Truth about Slime Molds, Spanish Moss, Lichens and Mistletoe
When leaves are covered with a blackish substance , similar to black soot that would have collected overnight, it is a sign of sooty mold. However, it usually appears in tow of parasite infestations that are much more serious, like aphids or scale insects. The Latin name of the fungus that develop are Capnodium oleaginum , or Fumago salicina. Spores from these strands develop on sweet honeydew produced by the parasites described above. The main reason sooty mold develops is the presence of insects and parasites like aphids, whiteflies, and scale insects. These parasites produce honeydew, which is a sweet and sticky substance.
Shot Hole Disease: Treatment and Prevention
Has the climate of rain, rain and more rain ended and rainfall become more normal? It seems that most of us are at least a little excited to have drier weather these days. The recent wet weather and our typical humidity may have increased the amount of fungal problems on fruit trees. Just like in your home, molds and fungus grow when there is an abundance of moisture. In truth, there are three types of diseases on plants: viral, bacterial and fungal. Often for bacteria and virus control we turn to controlling insects that spread the disease and then pamper the tree with proper soil moisture and adequate nutrition to aid it in recovery. However, with fungal issues on plants, we do have some remedies. There are a number of good fungicidal products out there that will, indeed, work.
Gray mold may be present during all stages of strawberry fruit development. Currently, it is not possible to obtain disease-free plants and this should.

Fungal Presence in Selected Tree Nuts and Dried Fruits
Trees in the genus Prunus , which includes plum, are susceptible to a fungal disease called black knot. Trees infected with black knot have swollen, hard, black knots on their branches. The disease is common on both wild and landscape trees and is easily diagnosed by the swollen, black galls that appear on infected branches. The fungus produces spores in the spring and early summer that are dispersed by splashing or windblown rain.
