Ethirimol on powdery mildew of crops is very good effect, mainly by its special action mechanism of decision. First of all, ethirimol and pathogen exposure, regardless of the mycelium, conidia, or insemination filament, has very strong bactericidal effect, and can restrain spore formation, blocking bacteria infection sources and pathways of again. The same general fungicides can only kill the pathogen spores of ethirimol on powdery mildew, the site of action of many, therefore, the sterilizing effect of ethirimol more comprehensive, more thorough. Secondly, ethirimol has protective and therapeutic function. Prior to the onset or early onset of use of ethirimol, can protect crops from the onset of the powdery mildew infection. For the pathogenesis of crop, ethirimol has good treatment effect, can eliminate had invasive plant bacteria, can significantly inhibit the bacteria growth.

Ethirimol has very excellent transfer within the suction performance. Ethyl phenol for seed treatment, effective components with plant conduction by root uptake, spread to every part of plant, so as to protect the entire crop of purpose. If the ethirimol is sprayed onto the leaf, effective component can be absorbed by leaves of conduction to new leaves, prevent disease spread to new leaves in the control of powdery mildew in the process, often the farmer reflected in the use of Difenoconazole, growth in the latter part of the plant dwarfing phenomenon; use of flusilazole after the field control of Strawberry Powdery mildew, a marked increase in the number of malformed fruit. While the use of25% ethyl phenol water, on Strawberry Growth without any adverse effects, after application of plant growth of normal. Melon powdery mildew, familiar was also put in a lot of problems. For example, in the" service of farming ability promotion"," vegetable", vegetable expert points out clearly: was not in use because of cucurbit vegetables, Triadimefon will seriously suppress cucurbit growth, use within 30 days after the melon growth especially slow, directly affects the economic benefit. Ethyl phenol not only safety to crops, flowers have effects on powdery mildew, rust, leaf spot of beans, banana leaf spot diseases have a good effect. Bees and other insects and natural enemies on the field such as biological activity also won't produce any adverse effect.
