Like other pesticides, fungicides are numerous and diverse.This complexity has led to diverse schemes for classifying fungicides. Classifications are based on inorganic (elemental sulfur and copper salts) vs organic, chemical structures (dithiocarbamates vs phthalimides), and, most successfully, mechanism of action (MOA).
There was a particularly bad crop failure due to multiresistant B. cinerea in strawberry in Florida in 2012; in that year and many other years, fludioxonil is the only fungicide still providing any protection. [1] Its mode of action is to inhibit transport-associated phosphorylation of glucose, which reduces mycelial growth rate. [2]
Fluazinam is a protectant fungicide, but is neither systemic or curative. It acts by inhibiting the germination of spores and the development of infection structures. Although it has activity against many fungi, it is less potent against rusts and powdery mildew and as such has not been commercialised for use in cereal crops.
Reports of individual pest species becoming resistant [1] are monitored by manufacturers, regulatory bodies such as the EPA and the Fungicides Resistance Action Committee (FRAC). [22] The risks of resistance developing can be reduced by using a mixture of two or more fungicides which each have activity on relevant pests but with unrelated ...
In 1997, it was the third most used fungicide in the US, behind only sulfur and copper, with 12 million pounds (5.4 million kilograms) used in agriculture that year. [3] Including nonagricultural uses, the United States Environmental Protection Agency (EPA) estimates, on average, almost 15 million lb (6.8 million kg) were used annually from ...
Acibenzolar-S-methyl has an unusual mechanism of action for a fungicide.It is not directly toxic to the fungus but instead activates the natural defences of the crop in a manner similar to the known role of salicylic acid and methyl jasmonate.
Metalaxyl is an acylalanine fungicide with systemic function. [3] Its chemical name is methyl N-(methoxyacetyl)-N-(2,6-xylyl)-DL-alaninate. It can be used to control Pythium in a number of vegetable crops, and Phytophthora in peas.
Boscalid is a broad spectrum fungicide used in agriculture to protect crops from fungal diseases. It was first marketed by BASF in 2002 using their brand name Endura . [ 3 ] The compound is an biphenyl amide derived inhibitor of succinate dehydrogenase .
