Embodiment 2

[0030] Example 2 Indoor toxicity determination test of the combination of isolongoneoxime lactam and bronopol to the pathogenic bacteria of tobacco wildfire disease.

[0031] Test method: Refer to "Indoor Bioassay Test Guidelines for Pesticides and Fungicides NY / T1156.16-2008" and use the turbidity method.

[0032] Statistical analysis was performed with DPS statistical analysis software, and the EC of each drug was calculated. 50 , and calculate the co-toxicity coefficient (CTC value) of the mixture according to Sun Yunpei's method, the co-toxicity coefficient (CTC) ≥ 120 shows the synergistic effect; the co-toxicity coefficient (CTC) ≤ 80 shows the antagonism; CTC)<120 showed an additive effect.

Embodiment 4

[0049] The contents of the following substances are all percentages by weight: isolongifolene oxime lactam 10%, bronopol 10%, naphthalenesulfonic acid formaldehyde condensate sodium salt 7%, sapinberry powder 3%, xanthan gum 1%, formaldehyde 0.2%, C 8-10 Fatty alcohol 0.1%, ethylene glycol 2%, deionized water to make up to 100%. The above-mentioned materials are mixed in proportion, uniformly dispersed by high-speed shearing, and sand-milled in a sand mill to prepare a 20% isolongifolactam-bronopol suspending agent.

[0050] The 20% isolongonexime lactam·bronopol suspension concentrate prepared above was used to prevent and treat tobacco wildfire disease. As can be seen from Table 4, 30 days E-E 0 The value is 26.20%, which shows that the combination of iso-longenone oxime lactam and bronopol has a synergistic effect on tobacco wildfire disease. At the same time, no phytotoxicity to tobacco was found after the application of 20% isofenone oxime lactam·bronopol suspension co...

Abstract

The invention discloses a sterilization compound containing isolongifolenone oxime lactam. The effective active components are composed of isolongifolenone oxime lactam and bronopol, and the weight ratio of isolongifolenone oxime lactam to bronopol is (20:1)-(1:10). The sterilization compound provided by the invention has the excellent prevention effect on diseases such as tomato bacterial wilt, tobacco bacterial leaf spot and soft rot of Chinese cabbage, has the long period of preserving effect, and is safe to crops. Isolongifolenone oxime lactam and bronopol have the outstanding synergisticeffect after being compounded, the pesticide usage dose can be decreased, the usage cost is lowered, pollution to the environment is relieved, generation of drug resistance of pathogenic bacteria is delayed, and the service life of pesticide is prolonged.

Description

technical field [0001] The invention relates to a pesticide fungicidal composition and its application field, in particular to a binary compound compounded with isolongonexime lactam and bronopol as effective active ingredients, which is mainly used in the prevention and control of diseases on crops. Background technique [0002] The chemical name of isolongifolactam is 2-(p-fluorophenyl)-5-isolongifolactam acyl-1,3,4-oxadiazole. The preparation process steps of the compound: using isolongifolenone as raw material, synthesizing isolongifolenone oxime by addition elimination reaction, and then performing Beckmann rearrangement reaction on isolongifolenone oxime to obtain the isolongifolenone oxime Lexenone oxime lactam. After a large number of tests, it has been shown that isolongoneoxime lactam has good control effect and inhibitory effect on bacterial diseases, and can inhibit such as Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, common Proteus and Pseud...
