Usage

Agricultural fungicide. It has excellent prevention and treatment effects on rice blast. Applying pesticides in the rice heading stage and grain filling stage has no effect on seed setting. When controlling rice blast and chestnut blast, use a concentration of 40r. For example, use 6000r/g wettable powder, add 75kg water per 50g powder, and spray about 1 mu; spray when the leaf blast reaches level 2, and it should be the first when the disease is serious. Spray again about 7 days after the second application. For the prevention and control of ear neck blast, spray it at about one-third of the rice field; when the ear neck blast is severe, in addition to spraying at the break stage, spray once at the full ear stage. The 0.4% powder can be sprayed directly, and the dosage is 1.5kg per mu. It is best to apply it in the morning and evening when there is dew, so that the powder can stick to the rice plants. In the experiments that have been found, kasugamycin has specific effects on preventing and curing tomato leaf mold with 20 ml of water, preventing bacterial angular leaf spot of watermelon, peach gum disease, scab, and perforation disease.

Instructions

It is mainly used for spraying and irrigating roots. The medication is started at the beginning of the onset, and the second medication is taken 7-10 days later. You can share it twice.

(1) To prevent and control cucumber anthracnose and bacterial angular spot disease, spray with 2% aqueous solution 400-750 times.

(2) To prevent tomato leaf mold, gray mold and cabbage black rot, spray with 2% aqueous solution 550-1000 times.

(3) To prevent and control cucumber wilt, irrigate the roots with 50-100 times of 2% water solution, spray the neck of the root or spray the diseased part.

(4) To prevent and control rice blast, spray with 500-600 times of 2% aqueous solution, and use the second medicine 7-10 days later.

(5) Kasugamycin is an ideal medicament for the prevention and treatment of various bacterial and fungal diseases. It has the functions of prevention, treatment and growth regulation. It is not only a special antibiotic for preventing and curing rice blast, but also against rice stripe disease, citrus gum disease, sａnd skin disease, kiwi fruit canker, pepper bacterial scab, celery early blight, kidney bean faint blight, water chestnut blight, etc. Have a good control effect.
