Problems solved by technology

There is no report on the compounding of pentothiastrobin and other fungicides
In addition, the existing pesticide compounding patents mainly only consider the synergistic effect brought about by the compounding. However, although the synergistic effect is the more obvious the better, it is not the only factor to be considered when using pesticides. In particular, it needs to be considered Yes, the toxicity and environmental pollution of the compounded composition
For example, although some active ingredients are not a big problem when they are used separately, after they are used in combination, the intermediate products produced during their degradation process may undergo adverse chemical reactions and cause environmental pollution problems

Abstract

The invention relates to a sterilization composition containing benzothiostrobin and triticonazole. The sterilization composition comprises active ingredients and pesticide preparation auxiliary components, especially the active ingredients comprise the benzothiostrobin and the triticonazole according to a weight ratio of 1: (0.04-25). As the benzothiostrobin and the triticonazole are compounded according to a specific proportion, a remarkable synergistic interaction effect is obtained, and many experiments prove that the compounded sterilization composition does not increase the toxicity to mammals. The sterilization composition obtains a remarkable synergistic interaction effect due to the compounding of the benzothiostrobin and the triticonazole by a certain proportion, the control effect is better than that of a single monomer, the dosage is small but the bacteriocidal spectrum is increased, and the composition has a special effect for ring spot, powdery mildew, rust disease, rot, net blotch, downy mildew and rice blast of fruit trees, vegetables and cereal crops. Furthermore, many experiments prove that the compounded sterilization composition does not increase the toxicity to mammals, is safe for crops and environment, and is beneficial to environment sustainable development.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a fungicidal composition containing benzathystrobin and fenconazole. Background technique [0002] Methoxyacrylate series fungicides are a kind of high-efficiency, broad-spectrum and environment-friendly fungicides developed by Syngenta in the 1980s. Penthiostrobin has received great attention and attention due to its wide range of bactericidal and herbicidal activities. [0003] Benzotystrobin has broad-spectrum fungicidal activity, not only has good control effect on cucumber downy mildew and powdery mildew, but also has good control effect on scab, anthracnose, gray mold, corn small spot, rice smut, banana wilt , Banana brown margin gray spot have excellent inhibitory activity. However, the long-term use of solvent alone makes the disease resistant to pesticides. The compounding of active ingredients with different action mechanisms is a general practice to delay the d...
