Problems solved by technology

It is mainly used for rice sheath blight, and can also be used for the control of rice smut and vegetable and cotton crop diseases. The disadvantage is that the effective period is short, generally 7 to 15 days. With the long-term use of Jinggangmycin, the control effect declined

Embodiment 1

[0020] Example 1: The composition of marine bacillus and Jinggangmycin for preventing and controlling rice sheath blight, the weight ratio of which is marine bacillus:jinggangmycin=1:0.005-0.01. According to the present invention, Jinggangmycin is dosed according to 10000 CFU / ug of marine bacillus and a concentration of 28%. The rest of the embodiments are also the same.

Abstract

The invention discloses a compound pesticide used for controlling paddy rice sheath blight. The invention belongs to the technical field of compound pesticides. The compound pesticide comprises bacillus marinus and jingganmycin, wherein a weight ratio of bacillus marinus to jingganmycin is 1:0.0005-500. According to the invention, because the two biological pesticides are different in action mechanisms, through the compounding of the two, a synergetic effect is developed, pesticide dosage is reduced, controlling effect is improved, controlling time is prolonged, and the occurrences of drug resistance are reduced.

Description

technical field [0001] The invention belongs to the technical field of compound pesticides, in particular to a compound pesticide for preventing and treating rice sheath blight. Background technique [0002] Rice sheath blight is a common and frequently-occurring disease of rice in my country. Common control agents include Jinggangmycin, etc. Jinggangmycin, also known as effective mycin, is a low-toxic fungicide. Jinggangmycin has strong systemic properties, is easily absorbed by mycelia and conducts rapidly in its body, inhibiting the growth and development of mycelium. It is mainly used for rice sheath blight, and can also be used for the control of rice smut and vegetable and cotton crop diseases. The disadvantage is that the effective period is short, generally 7 to 15 days. With the long-term use of Jinggangmycin, the control effect has declined. [0003] Marine Bacillus B-9987 belongs to a class of biocontrol bacteria belonging to the genus Bacillus. The wild strain...
