Complex pesticide composition containing oxine-copper and thiabendazole

Abstract

The invention discloses a complex pesticide composition containing oxine-copper and thiabendazole. The complex pesticide composition contains active components oxine-copper and thiabendazole, wherein the weight ratio of oxine-copper to thiabendazole is (0.125-8):1. The complex pesticide composition maintains the advantages of little phytotoxicity of oxine-copper and prevention and control effect of thiabendazole on multiple crop diseases; the two pesticide preparations with different action mechanisms synergistically produce optimal pesticide effects, thus the complex pesticide composition has good prevention and control effect, wide disease prevention and control range and low toxicity, and does not tend to generate pesticide resistance. In addition, the mixed preparation is convenient to use, and blending is not needed when a farmer uses the mixed preparation, thereby reducing the labor cost and avoiding excessive use due to improper mixing of the pesticide preparation.

Description

technical field

[0001] The invention relates to a pesticide composition, in particular to a compound pesticide composition for preventing and treating grape black pox and anthracnose. Background technique

[0002] Thiabendazole (Thiabendazole), molecular formula shown in the following formula (I), is an antifungal agent, belongs to a protective therapeutic agent, has a penetrating effect, and can show effect under a concentration of 200ppm during a field test, and is effective for various plants. The control effect can be used in a wide range, and it is a broad-spectrum medicament. This agent has been officially recommended in the prevention and treatment of citrus black spot, peanut crown rot, banana shaft rot, tobacco white spot, banana anthracnose, rice seedlings excessive growth disease, asparagus stem blight, pear ring spot, asparagus brown spot , Yam leaf spot, yam stem blight, mushroom brown spot, mushroom brown pox, etc.

Examples

Embodiment 1

[0025] In order to verify the inhibitory effect of quinoline copper and thiabendazole compound pesticides on anthracnose bacteria, the laboratory measurement of the inhibition rate of anthracnose bacteria by quinoline copper and thiabendazole compound pesticides with different proportions was carried out, according to Table 1 The weight percentage in -4 is made into corresponding concentration, carries out laboratory anthracnose bacterium inhibition test, to measure the anthrax bacterium inhibition rate. The determination method is as follows:

[0026] Put 100ml of water in a 250ml Erlenmeyer flask, the water contains 3.9g of PDA (potato dextrose agar), sterilized by high temperature and high pressure (121°C, 1 standard atmospheric pressure, 15 minutes), put it in a 60°C oven after decompression, After cooling down to 55°C, in the aseptic operating table, add the agents to be tested in Table 1-4 and mix evenly with the PDA medium. The dilution factor used is shown in Table 1-4...
