Abstract

The invention discloses a composition comprising Bacillus subtilis and procymidone, and an application thereof. The active ingredients of the composition are Bacillus subtilis and procymidone, and a mass ratio of the Bacillus subtilis to the procymidone is 4:1 to 1:4. The invention also discloses the application of the composition containing Bacillus sp. Pc3 and procymidone in the prevention and control of Sclerotinia sclerotiorum. Compared with single doses, the sterilizing composition of the invention has the advantages of obvious synergistic effects on the prevention and control of Sclerotinia sclerotiorum, significant improvement of the prevention and control effect, reduction of the potential resistance risk of Sclerotiorum sclerotiorum pathogens to procymidone, reduction of the dosage of chemical pesticides, effective reduction of the pesticide residues and environmental pollution of agricultural products, and safeness to humans, animals, beneficial organisms and the environment.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a bacillus subtilis ( Bacillus sp.) Composition of Pc3 and saccharin and its application in the control of Sclerotinia sclerotiorum. Background technique [0002] by Sclerotinia ( Sclerotinia sclerotiorum Sclerotinia sclerotiorum caused by ) is one of the important diseases in rapeseed production. The annual rate of diseased plants is 10% to 30%, and the serious ones can reach more than 80%. Diseased plants generally reduce yield by 10% to 70%. Rapeseed is one of the oil crops with the highest oil production efficiency. At present, the main control measures for Sclerotinia sclerotiorum are chemical control, agricultural control and biological control. But so far, no highly effective antibacterial sclerotinia varieties have been found. Therefore, chemical control methods are mainly used for the prevention and control of the disease, and benzimidazole fungicides are the most used. Wit...
