Embodiment 1

[0017] Biological Example 1: Indoor Toxicity Test of Zhongshengmycin Mixed with Tebuconazole in Different Proportions to Apple Spotted Deciduous Disease

[0018] Treatment agents: Zhongshengmycin · Tebuconazole wettable powder (developed and produced by Shaanxi Welch Crop Protection Co., Ltd.), 3% Zhongshengmycin wettable powder (Rui Defeng Biotechnology Co., Ltd., Dongguan City, Guangdong Province, commercially available), 25% tebuconazole wettable powder (Jiangsu Qizhou Green Chemical Co., Ltd., commercially available).

[0019] The growth rate method was used for determination. Firstly, each proportioning is made into 5 series of concentration gradients, and the synergistic test is carried out according to the synergistic test method, and the EC of the 5 proportioning mixtures and single doses are calculated. 50 value, calculate the co-toxicity coefficient, and judge whether it has a synergistic effect. The judgment standard is that the co-toxicity coefficient is signific...

Embodiment 2

[0031] Example 2 50% Zhongshengmycin·tebuconazole wettable powder

[0032] Zhongshengmycin 2%, tebuconazole 48%, sodium lauryl sulfate 4%, alkylnaphthalene sulfonate formaldehyde condensate 8%, white carbon black 10%, bentonite 28%, mixed to make 50% medium Shengbactin·tebuconazole wettable powder.

[0033] Effect Test of 50% Zhongshengmycin and Tebuconazole WP on Controlling Apple Leaf Spot

[0034] Control agents: 3% Zhongshengmycin wettable powder (commercially available), 25% tebuconazole wettable powder (commercially available).

[0035] The experiment was arranged at the Weinan Fruit Tree Research Institute in Shaanxi Province. The pre-medication survey was carried out to calculate the disease index of apple leaves. The first application of the drug was on May 5th, and the application was once every 10 days for 3 times. The experimental results are shown in Table 3:

Embodiment 3

[0039] Example 3 60% Zhongshengmycin·tebuconazole wettable powder

[0040] Zhongshengmycin 3%, tebuconazole 57%, sodium lauryl sulfate 5%, alkylnaphthalene sulfonate formaldehyde condensate 10%, white carbon black 8%, light calcium carbonate 17%, made by mixing 60% Zhongshengmycin·tebuconazole wettable powder.

[0041] Effect of 60% Zhongshengmycin and Tebuconazole WP on Controlling Rice Smut Disease

[0042] Control agents: 3% Zhongshengmycin wettable powder (commercially available), 25% tebuconazole wettable powder (commercially available).

[0043] The experiment was arranged in Xiaodian Village, Datong Town, Tianchang City. The terrain of the test area was flat. The disease index was investigated before the drug was administered. The drug was administered for the first time on August 3, and the drug was applied every 7 days. The drug was applied 3 times in total, and a blank control area was set.

Abstract

The invention relates to a germicide composition. The composition is wettable powder of which an effective component consists of zhongshengmycin and tebuconazole, wherein the weight percentage of the zhongshengmycin to the tebuconazole in the effective active component is between 5:1 and 1:60. The germicide composition has the advantages of obvious synergy and small dosage, is used for controlling the fungal diseases of fruit trees and grain, and is particularly suitable for controlling apple alternaria leaf spot, rice false smut or banana leaf spot.

Description

Technical field: [0001] The invention belongs to the technical field of pesticides, and relates to a fungicide compounded with Zhongshengmycin and tebuconazole, which is used for the prevention and treatment of diseases on grains and fruit trees. technical background: [0002] Zhongshengmycin belongs to a kind of N-glycoside antibiotics. It has a broad antibacterial spectrum and has good effects on various bacteria and fungi. It has good effect on Gram-negative and positive bacteria, especially has obvious antibacterial activity on crop pathogenic bacteria such as vegetable soft rot, Xanthomonas cucumber, Xanthomonas oryzae, and Wheat scab. And there is no cross-resistance with conventional preparations. [0003] Tebuconazole, a triazole fungicide, is a systemic fungicide with protective and therapeutic effects. It is an ergosterol biosynthesis inhibitor, which can be quickly absorbed by the growing part of the plant and mainly transferred to the top. Tebuconazole not only...
