Diseases and Pests:-
If the mushroom is not taken care of, many diseases and peats attack it.
- Green fungus (Trichoderma viridae): This is the most common disease in oyster mushrooms where green spots appear on the cubes.
Control: Dip the cloth in Formalin solution (40%) and wipe the affected area. If mildew attacks more than half the cube, then the entire cube must be removed. Care should be taken to ensure that the contaminated cube is burnt or buried at a place far enough away from the cropping room to prevent re-infection.
- Flies : Scarid flies, phorid flies, cecid flies have been observed to attack the smell of mushrooms and spawn. They lay eggs on husk or mushrooms or eggs arising from them and destroy the crop. Eggs mycelium subsist on mushrooms and enter the fruit-producing body and become unsuitable for consumption.
Control: Curtain doors, windows or skylights, if any, 30 mesh nylon or wire net to prevent entry of large flies during the harvest period. Use mushrooms or flies to dispense in mushroom houses.
- Mites: These are very thin and crawling small insects which appear on the body of mushrooms. They are not harmful, but when they are present in large numbers the producer is worried about them.
Control: Keep home and environment clean and tidy.
- Shambook, snail: These peats eat up the entire portion of the mushroom which later become infected and adversely affect the quality of the bacteria crop.
Control: Remove the peats from the cube and kill them. Maintain a clean and tidy condition.
5 . Rodents: Attack of the rodents is mostly found in low-priced mushroom houses. They eat the grain spawn and make holes inside the cubes.
Control: Use of rat poison feed in mushroom houses. Close the bills of the mice with glass pieces and plaster.
- Ink cap (Coprinus sap) This is a weed of mushrooms that grow on the cubes before harvest. They later split into black slimming mosses at maturity.
Control: Only the recommended control measures can physically remove the coprinus from the cube.
