Copper sulfate is an effective fungicide allowed in organic farming, but can cause harm to the host plant. Addition of lime hampers this effect. [13] Neem oil effectively manages powdery mildew on many plants by interfering with the fungus' metabolism and terminating spore production. [13]
White mold affects a wide range of hosts and causes sclerotinia stem rot. It is known to infect 408 plant species. As a nonspecific plant pathogen, [3] diverse host range and ability to infect plants at any stage of growth makes white mold a very serious disease. The fungus can survive on infected tissues, in the soil, and on living plants.
Checking plant labels should provide information on type of tomato, growth type, and ultimate size of the plant. Large tomato varieties, such as Big Boy or Beefsteak, are not as suitable for ...
The fungus Trichoderma viride is a biocontrol agent that has proven to control this disease in an environmentally friendly manner. It can also manage Fusarium wilt in cucumber, tomato, and various other crops. [citation needed] F.oxysporum f. sp. radicis-cucumerinum is responsible for the root and stem rot of cucumbers (Cucumis sativus). [13]
Alternaria alternata is a fungus causing leaf spots, rots, and blights on many plant parts, and other diseases. It is an opportunistic [ citation needed ] pathogen on over 380 host species of plant.

[6] Plants located under pecan or hickory trees are particularly susceptible to sooty mold, because honeydew-secreting insects often inhabit ...
Senescent leaves with early blight infections and leaves with flea beetle injury are especially important spore sources because the fungus can colonize and produce new spores in these wounded areas. The growth of C. coccodes is most rapid at 80 °F (27 °C), although the fungus can cause infections over a wide range of temperatures between 55 ...
Tomato plants are available that have been engineered with resistant genes that will tolerate the fungus while showing significantly lower signs of wilting. [2] Verticillium albo-altrum, V. dahliae and V. longisporum can overwinter as melanized mycelium or microsclerotia within live vegetation or plant debris. As a result, it can be important ...
