嘧霉胺是一种杀菌剂，属于苯胺基嘧啶类，特别是甲氧基丙烯酸酯类。长时间暴露于两种环境相关浓度的嘧霉胺后，意大利树蛙 H. intermedia 的组织可能会发生组织学变化并表现出多种毒性反应（5 和 50 µg/L）[2]。在三天培养的培养基中，嘧霉胺降低多聚半乳糖醛酸酶、纤维素酶、蛋白酶和漆酶的活性。对于多聚半乳糖醛酸酶、纤维素酶和蛋白酶，嘧霉胺引起的总酶活性 (IC50) 降低 50% 约为 0.25 μM，对于漆酶，约为 1.0 μM[3]。

Pyrimethanil is a member of the class of aminopyrimidines that is N-phenylpyrimidin-2-amine carrying two additional methyl substituents at positions 4 and 6. A fungicide used to control grey mould on fruit, vegetables and ornamentals as well as leaf scab on pome fruit. Also commonly employed to control Botrytis cinerea throughout the winemaking process in grapes, must, fermenting must and wine. It has a role as an aryl hydrocarbon receptor agonist, an environmental contaminant, a xenobiotic and an antifungal agrochemical. It is an aminopyrimidine, a secondary amino compound and an anilinopyrimidine fungicide.
Pyrimethanil has been reported in Ganoderma lucidum with data available.
Pyrimethanil is a fungicide used on grape vines.

Mechanism of Action
/Its mode of action is/ inhibition of the secretion of fungal enzymes relevant for pathogenicity.
The effect of pyrimethanil on the levels of cell wall degrading enzymes secreted by Botrytis cinerea Pers. was investigated in diseased plant tissues and in liquid B. cinerea cultures. Total proteinase activity isolated from infected carrot slices which were treated with 5.0 uM pyrimethanil was decreased by 76%, 3 d after inoculation. Polygalacturonase, cellulase, proteinase and laccase activities were all decreased in the medium of three day-old cultures grown in the presence of pyrimethanil. The pyrimethanil concentrations resulting in 50% reduction in total enzyme activities (IC50) were approximately 0.25 uM for polygalacturonase, cellulase and proteinase, and approximately 1.0 uM for laccase. No significant growth inhibition was observed at these pyrimethanil concentrations. Pyrimethanil did not inhibit the enzymes directly, nor did it inhibit the synthesis of cytosolic proteins. Therefore, it was proposed that the fungicide inhibits protein secretion at a post-translational stage in the secretory pathway. Large differences were found in the effects of pyrimethanil on the growth of B. cinerea in liquid cultures and on agar plates, depending on the composition of the medium. In liquid media containing cellulose and protein as carbon and nitrogen sources, growth inhibition occurred at 5.0 uM pyrimethanil, whilst no growth inhibition was observed with 50 uM pyrimethanil in malt extract. Similarly, growth occurred on potato/dextrose agar (PDA) at 0.5 uM pyrimethanil, but no growth was seen at this concentration on agars containing cellulose and protein. Thus it appears that pyrimethanil is most active in media where the fungus has to utilise extracellular enzymes to mobilise the nutrients it requires for growth.
