Problems solved by technology

In addition, if the fungicide is used alone for a long time, it is easy to induce the resistance of pathogenic bacteria, which will lead to a decrease in the efficacy of the drug and an increase in the dosage.
[0006] So far, no relevant studies or reports have been found on the compounding of benzothiastrobin and thiocarbamate fungicides

Embodiment 1

[0057] Example 1 Efficacy test of 30% phenthiastrobin · Propineb wettable powder in the control of capsicum anthracnose

[0058] Prozeb 25%, Penthiastrobin 5%, Sodium Lauryl Sulfate 2%, Lignosulfonate 3%, Polycarboxylate 3%, Filler Kaolin make up 100%. The mixture was mixed according to the above ratio, and pulverized by an airflow mill to obtain 30% phenthiastrobin·propineb wettable powder. The preparation is diluted 500 times and sprayed, and sprayed at the early stage of the disease, and the active ingredient dosage per mu is 10g. The medicine was applied every 7 days, and the medicine was applied 3 times in total. The disease index was investigated 7 days and 14 days after the last medicine, and the control effect was calculated. The control effects of pepper anthracnose on 7 days and 14 days after spraying were 90.35% and 86.20%, respectively.

[0060] Example 2 Drug Efficacy Test of 45% Penthiastrobin · Zinc Wettable Powder in Controlling Apple Spot

[0061] Zinc 30%, penthiostrobin 15%, sodium dodecylbenzene sulfonate 3%, calcium lignosulfonate 5%, kaolin supplement 100%. The mixture was fully mixed according to the above ratio, and pulverized by an airflow mill to obtain 45% fenthiastrobin · zinc zinc wettable powder. The preparation was diluted 750 times and sprayed, sprayed at the early stage of the disease, the active ingredient dosage per mu was 10g, and the medicine was applied once every 7 days, and the medicine was applied 3 times in total. The disease index was investigated and the control effect was calculated 7 days and 14 days after the last medicine. . The control effects of apple spot disease on 7 days and 14 days after application were 90.16% and 92.50%, respectively.

Abstract

The invention relates to pesticide bactericidal composition. Active components comprise benzothiostrobin and one of propineb, zineb and mancozeb in a weight ratio of 1:(0.05-60). According to the composition, the benzothiostrobin and the propineb, the zineb or the mancozeb are compounded within a certain proportion range; 1, the very significant synergistic effect is realized, the composition can also control frequently-occurring diseases of crops, pesticide applying numbers are reduced, and the cost is saved; 2, the two active components in the bactericidal composition are two kinds of bactericides with different action mechanisms, so that the controlling spectrum is enlarged, and the production of the drug resistance is slowed down; 3, the synthesis process route of the propineb, the zineb and the mancozeb in the composition is mature, the capacity is high, and the price is low, so that through compounding with the benzothiostrobin, the production cost is reduced and resources are saved on the premise that the efficacy is guaranteed.

Description

technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a fungicidal composition containing benzathystrobin. Background technique [0002] Methoxyacrylate series fungicides are a kind of high-efficiency, broad-spectrum and environment-friendly fungicides developed by Syngenta in the 1980s. This type of fungicide has been greatly favored and paid attention to by people because of its wide range of sterilization. [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, long-term use alone can easily make the disease resistant to pesticides. The compounding of active ingredients with different action mechanisms is a general practice to delay the development of diseas...
