Function characteristics: Isocarbazide is a broad-spectrum contact-type protective pesticide fungicide , but it also has a certain therapeutic effect. It can inhibit the germination and production of fungal spores, and also control the growth of mycelium, which has an impact on the developmental stages of pathogenic fungi. In biochemistry, recent findings show that iprodione inhibits protein kinases. Thus, intracellular signals that control many cellular functions, including the interference of carbohydrate binding into fungal cell components.
Applicable crops: citrus, apple, pear, apricot, cherry, peach, plum, grape, strawberry, garlic, onion, corn, wheat, barley, rice, melon, cucumber, cantaloupe, watermelon, soybean, pea, eggplant, tomato, pepper , potatoes, radishes, celeriac, celery, wild lettuce, garden flowers, lawns, etc. It is also used for preservation of citrus, banana, apple, pear, peach and other fruits during storage.
Targets for control: Isobacteria have a wide spectrum of fungi, and can control fungi that are resistant to benzimidazole systemic fungicides. The main control objects are Botrytis, Cladosporium, Penicillium, Sclerotinia, Alternaria, Helminthosporium, Rhizoctonia, Stem, Species, Cercospora Diseases caused by various crops, fruit trees and fruits during storage, such as grape gray mold, sclerotinia on stone fruit trees, apple spotted leaf disease, pear black spot, tomato early blight, strawberry, vegetable gray mold All have good control effects.
Application technology 1. Prevention and treatment of apple spotted deciduous apples When the spring shoots of the spring shoots begin to spray, the spraying is started. After 10 to 15 days, the spray is sprayed a second time, and the autumn shoots are sprayed once more. Each time, 50% iprodione suspension or wettable powder 1000-1500 times solution or 50% iprodione 66.7-100 ml per 100 liters of water (effective concentration 333-500 mg / liter).
2, prevention and control of grape gray mold can be applied to the grape torus fall off, grape bunches stop growing, maturity start and 3 weeks before harvest, if the flowering period or the beginning of flowering begins to occur, you can add a drug, each time per acre Use 50% suspension or wettable powder 60-100 ml (g) (active ingredient 30-50 g).
3. Prevention and treatment of strawberry gray mold In the early stage of strawberry onset, the medicine is sprayed once every 8 days, and the application is stopped 2 to 3 weeks before the harvest. Spray 50 ml of a suspension or a wettable powder of 100 ml (g) (50 g of active ingredient) per acre.
4. Control flower rot, apricot, gray mold, and flower rot in the fruit tree (apricot, cherry, peach, plum, etc.), and spray the flower rot once in the flowering and flowering stages of the fruit tree. Gray star disease is sprayed once every 3 to 4 weeks and 1 to 2 weeks before fruit harvest. Gray mold is administered 1 to 2 times depending on the condition of the disease before harvest. Water sprayed with 50% suspension or wettable powder of 66-100 ml (grams) (active ingredient 33-50 g) per acre.
