It is a traditional bactericide and is an anilinopyrimidine. It is a fungicide with high activity in controlling traditional Chinese medicine for gray mold, tomato gray mold and blight.
The mechanism of action is unique, which prevents the infection of the pathogen and kills the pathogen by inhibiting the production of the enzyme-impregnated enzyme.
It is highly effective against the commonly used non-anilinopyrimidines (benzimidazoles and carbamates) fungicides, and mainly inhibits the growth of germ tubes and mycelial growth of Botrytis cinerea. It also has a certain inhibitory effect on spore germination of Botrytis cinerea within a certain period of time.
At the same time, it has the functions of internal absorption and fumigation. After application, it can quickly reach the parts of the plant where flowers and young fruits cannot reach the spray, killing the bacteria.
It has the functions of protection and treatment. It is a high-efficiency and low-toxic fungicide for controlling gray mold and blight. It has systemic conduction and fumigation effects. It can be quickly transferred to various parts of plants after application.
It effectively inhibits the production of pathogenic bacteria infecting enzymes, thereby preventing the infection of the bacteria and completely killing the bacteria. It has no cross-resistance with other fungicides, and it has very good protection and therapeutic effect when used at low temperatures. It is used to control cucumber, tomato, grape, strawberry, pea, leeks, and other crops such as gray mold, blight, fruit black star disease, and spotted leaf disease.
Prevention and control of gray mold caused by cucumber tomato, etc. Before or after the onset, use 40% of pyrimethanil 25-95g per acre, 800-1200 times of water, 30-75kg of water per mu, large plant, high drug volume and high water content; Small, low dose and low water volume, used once every 7-10 days, sharing 2-3 times. It takes more than 4 times to control a growing season, and should be rotated with other fungicides to avoid resistance. Open field medicine should be selected in the morning and evening, the wind is small and low temperature.
Control grape gray mold, spray 40% suspension or wettable powder 1 000-1500 times liquid, when the cloth needs to be applied more than 4 times during the growing season, it should be used with other fungicides to avoid drug resistance.
Pyrimethanil can also be used in apples, pears, strawberries, leeks, beans and other crops.

Application |
1.Pyrimethanil has protective activity in control of gray mould and both protective and curative activity in control of leaf scab. 2.Pyrimethanil is inhibitor of methionine biosynthesis leading to inhibition of the secretion of enzymes necessary for infection. 3.Pyrimethanil has good effective to control of gray mould on vines, fruit(such as strawberry), vegetables(such as tomato and cucumber) and ornamentals, control of leaf scab on pome fruit such as apple and pear. |
