Pyrimethanil Molecular Formula
Synonyms: 4,6-Dimethyl-N-phenyl-2-pyrimidinamine; N-(4,6-dimethylpyrimidin-2-yl)aniline; 4,6-dimethyl-N-phenylpyrimidin-2-amine
Pyrimethanil is pyrimidinamine fungicide, with penetration and root absorption activity of leaves, grapes, strawberries, tomatoes, onions, beans, cucumber, eggplant and ornamental plants of Botrytis cinerea have excellent control effect. Apple black fishy on fruit trees also disease has good prevention effect.
Pyrimethanil is anilinopyrimidine class. As Botrytis cinerea, Botrytis cinerea, Fusarium wilt higher fungicide activity in the prevention and treatment of current traditional medicines.
Unique mechanism of action, by inhibiting the enzyme production of bacteria disseminated to prevent bacteria infection and kill bacteria.
Commonly used non anilinopyrimidine class (benzimidazoles and Carbamate) fungicide resistance to Botrytis cinerea has produced a strong effect, mainly inhibit mold Botrytis cinerea of germ tube elongation and mycelial growth in Botrytis cinerea mold spores germinate within a certain time with a certain effect of medication.
Both the uptake and fumigation, quickly reached after application plants flower, young fruit and other spray can not reach the site of killing germs, especially after adding a halogen effects penetrant, increase in leaf and fruit adhesion and penetration time speed, is conducive to absorption, making faster, more stable efficacy, currently 41% of the successful synthesis of poly astatine pyrimethanil. In addition pyrimethanil insensitive to temperature, at a relatively low temperature application does not affect the efficacy.
Pyrimethanil has the protection and treatment, prevention and treatment of botrytis, a blight efficient, low toxicity fungicides, with the uptake and fumigation, after application can quickly spread to various parts of plants, effectively inhibiting pathogens Infection enzyme production, thereby preventing pathogen infection, kill the bacteria. No cross-resistance with other fungicides, and use at low temperatures, there is still a very good protective and therapeutic effects. For control of cucumber, tomatoes, grapes, strawberries, peas, leeks, and other crops Botrytis cinerea, Fusarium wilt and fruit scab, leaf spot disease.
Prevention cucumber tomato gray mold, prior to the onset or early acre with 40% pyrimethanil 25-95g, watered 800-1200 times, acres of water 30-75kg, plants, high doses of high water; plants Small, low doses of low water, once every 7-10 days, sharing 2-3 times. Prevention growing season need medication more than 4 times, should be used with other fungicides rotation, to avoid resistance. Vegetables in open air medicine sooner or later to be elected a small, low temperature.
Control of grape gray mold, spray 40% WP 1000-1500 suspensions or times, when the growing season for an applicator cloth over four times, should cooperate with other fungicides Hybrids use, to avoid medicine resistance.
Pyrimethanil also be used for apples, pears, strawberries, leeks, beans and other crops
Not with food, seeds, mix drinks during storage.
Sunny 8:00 to 17:00, the air relative humidity below 65% use; temperatures above 28 degrees should stop spraying.
