Jinggangmycin is an antibiotic produced by actinomycetes. It has strong absorbability, is easy to be absorbed by thallus cells and rapidly conducts in it, interfering with and inhibiting the growth and development of thallus cells. The application range is mainly used for rice sheath blight, and can also be used for preventing and controlling rice false smut, corn leaf spot, vegetable, cotton, bean and other crop diseases.
Control of Rice Diseases
Rhizoctonia solani is usually sprayed or poured on the middle and lower parts of rice after sealing and before heading or at theearly stage of full development, with 5% soluble powder of 100-150g per mu and 75-100kg of water added, with an interval of 7-15days and 1-3 times of application. Rice false smut is sprayed with 5% aqua 100-150ml and water 50-75kg per mu at the booting stage of rice.
solution, a small amount of water is evenly sprayed on the wheat seeds, the mixture is evenly stirred, and the seeds are sowed after being piled for a few hours. It can also be sprayed with 100-150ml of 5% jinggangmycin aqua and 60-75kg of water per mu when the diseased plant rate in the field reaches about 30%.
