Problems solved by technology
[0007] At present, the prevention and control of plant pathogens is becoming more and more difficult. On the one hand, with the change of planting structure, the planting area of economic crops such as melons, fruits and vegetables has gradually expanded, and the degree and number of diseases have increased, making the prevention and control more difficult. On the other hand, the resistance of pathogenic bacteria is increasing year by year under the pressure of continuous agent selection, the control effect of a single agent is greatly reduced, and the control of plant diseases is facing a major challenge

The invention discloses a sterilization composition containing benthiavalicarb-isopropyl and isoprothiolane and application thereof. The sterilization composition containing the benthiavalicarb-isopropyl and the isoprothiolane takes the benthiavalicarb-isopropyl and the isoprothiolane as main active components, and the weight ratio between the benthiavalicarb-isopropyl and the isoprothiolane is 1-70:1-50. The invention further discloses the application of the sterilization composition for preparing prevention and cure drugs of resistance plant fungi diseases. The application can be applied to prevention and cure of cereal, fruit tree and vegetable diseases and has high synergistic effects, and the drug resistance of germs is overcome and postponed; and the sterilization speed is quick, the lasting period is long, the application cost is lowered, and the prevention and cure effect is obviously superior to single agent utilization. The sterilization composition containing the benthiavalicarb-isopropyl and the isoprothiolane can be applied to prevention and cure of the fungi diseases in crops, in particular to prevention and cure of the fungi diseases such as phytophthora disease, late blight, downy mildew and rice blast, and the effect of the sterilization composition is better than single agent utilization.
Description
technical field [0001] The invention relates to a bactericidal composition and its application, in particular to a bactericidal composition containing benthiazil and rice blastexin and its application. Background technique [0002] Benthiavalicarb-isopropyl, molecular formula: C 18 h 24 FN 3 o 3 S, chemical name: [[(6-fluorobenzothiazol-2-yl)-ethylcarbamoyl]-2-methylpropyl]carbamate isopropyl ester. [0003] Benthiopyram has good bactericidal activity against Phytophthora, and it has a good inhibitory effect on the formation of sporangia and the germination of sporangia at low concentrations, but it has a good inhibitory effect on the release of zoospores and the movement of zoospores. No effect. In field trials, benthiazil was used at a lower dose (25-75g a.i. / hm 2 ) can effectively control late blight of potato and tomato, downy mildew of grape and other crops. [0004] Isoprothiolane, molecular formula: C 12 h 18 o 4 S 2 , chemical name: 1,3-dithiopentane-2-dii...
