Embodiment 1

[0016] Biological Assay Example 1: Indoor Toxicity Test and Formula Screening of Copper Quinoline and Epoxiconazole Compound on Pseudomonas citrus Anthracnose.

[0017] The inventor, through a large number of screening tests, used the Sun Yunpei method to analyze the synergistic effect of copper quinoline and epoxiconazole in different proportions, and found that within a certain range of proportions, copper quinoline and epoxiconazole mixed with citrus Anthrax bacteria have a synergistic effect.

[0018] Test materials: citrus anthracnose diseased leaves collected from the field, separated and purified in the laboratory for future use.

[0019] Test method: refer to NY / T 1156.6-2006. That is, first weigh a certain quality of 98% quinoline copper original drug, add chloroform to fully dissolve; use 96.8% epoxiconazole original drug, add acetone to fully dissolve, then dilute with 0.1% Tween 80 aqueous solution, respectively prepared into single According to the purpose of mi...

Embodiment 1

[0026] Formulation Example 1: 50% copper quinoline · epoxiconazole water dispersible granules.

[0027] Quinoline copper 30%, epoxiconazole 20%, alkyl naphthalene sulfonate (wetting agent) 5%, sodium lauryl sulfate (dispersant) 6%, polycarboxylate (dispersant) 4%, Sodium chloride (disintegrant) 2%, polyethylene glycol (binder) 3%, soluble starch (stabilizer) 3%, kaolin (filler) make up to 100%. Dry pulverize the above formula according to the proportion, granulate, dry and sieve to prepare 50% quinoline copper · epoxiconazole water dispersible granules. This preparation example is used for preventing and treating citrus anthracnose. In September 2010, an experiment was carried out in a farmer's citrus orchard in Longhua Town, Boluo County, Huizhou City, Guangdong Province, and each treatment was repeated 4 times.

[0028] Table 2 is the field test scheme of 50% quinoline copper · epoxiconazole water dispersible granules for the control of citrus anthracnose.

Abstract

The invention relates to a pesticide composition containing oxine-copper and epoxiconazole, wherein the pesticide composition includes the oxine-copper as a first active ingredient and the epoxiconazole as a second active ingredient of; the weight part ratio of the oxine-copper to the epoxiconazole is 20:1 to 1:30, and preferably 10:1 to 1:5. In the pesticide composition provided by the invention, the two active ingredients are compounded to provide an obvious synergistic action, and therefore, the control effect is improved. The pesticide composition is suitable for controlling anthracnose and bacterial spot of crops.

Description

technical field [0001] The invention relates to a pesticide composition. The first active ingredient is copper quinolate, and the second active ingredient is epoxiconazole. Background technique [0002] During the growth and development of crops, they are susceptible to various diseases. For a long time, chemical control has been the main effective means of disease control. However, due to single and unscientific drug use in recent years, a variety of pathogenic bacteria have developed resistance to the currently used pesticides, such as anthracnose, bacterial angular leaf spot and other drug resistance are very common, and have become a major problem in chemical control . Due to the resistance of bacteria, frequent application of pesticides has increased the burden on farmers and environmental pollution. In some areas where diseases have occurred seriously, conventional pesticides alone are difficult to prevent and control, and the effect is very poor, seriously affecting ...
