Embodiment 1

[0014] Biological Assay Example 1: Indoor Toxicity Determination of Copper Quinoline and Prochloraz to Pseudomonas spp.

[0015] The inventor, through a large number of screening tests, used the Sun Yunpei method to analyze the synergistic effect of copper quinoline and prochloraz compositions in different proportions, and found that within a certain proportion range, the combination of copper quinoline and prochloraz would cause apple spots The deciduous bacteria have a synergistic effect.

[0016] Test materials: Apple leaf spot diseased leaves collected from the field, separated and purified in the laboratory for future use.

[0017] 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 97% prochloraz original drug, add acetone to fully dissolve, then dilute with 0.1% Tween 80 aqueous solution, respectively prepared into a single According to the purpose of mixing, set a...

Embodiment 1

[0026] Formulation Example 1: 40% copper quinoline · prochloraz water dispersible granules.

[0027] Quinoline copper 20%, prochloraz 20%, sodium lauryl sulfate 6%, dispersant polycarboxylate 4%, disintegrant sodium chloride 2%, binder polyethylene glycol 3%, stable Agent soluble starch 3%,

[0028] Kaolin makes up to 100%. Dry pulverize the above formula according to the proportion, granulate, dry, and sieve to prepare 40% copper quinoline·prochloraz water-dispersible granules.

[0029] This embodiment is used for preventing and treating citrus anthracnose, 40% quinoline copper prochloraz water dispersible granule dosage 225g a.i. / hm 2 Spray with water, the control effect is 93.4% 10 days after the application; the dosage of 33.5% quinoline copper suspension is 300g a.i. / hm 2 Spray with water, the control effect is 84.2% 10 days after application; the dosage of 40% prochloraz water emulsion is 300g a.i. / hm 2 Sprayed with water, the control effect was 83.1% 10 days after...

Embodiment 3

[0035] Preparation Example 3: 30% copper quinoline · prochloraz wettable powder.

[0036] Copper quinoline 15%, prochloraz 15%, pull open powder 3%, naphthalene sulfonate formaldehyde condensate 6%, talcum powder 15%, kaolin make up to 100%.

[0037] The above formula is coarsely pulverized in proportion, put into a mixer and mixed evenly, and then jet pulverized to obtain 30% copper quinolate·prochloraz wettable powder.

[0038]This embodiment is used for preventing and treating apple spot defoliation, and the effective dosage of 30% quinoline copper prochloraz wettable powder is 120 mg / kg mixed with water and sprayed, and the control effect is 94.0% 14 days after the medicine. The effective dosage of 33.5% quinoline copper suspension is 150mg / kg mixed with water and sprayed, and the control effect is 85.5% after 14 days of application. The effective dosage of 40% prochloraz aqueous emulsion is 150 mg / kg mixed with water and sprayed, and the control effect is 84.8% 14 days...

Abstract

The invention discloses an oxinecopper and prochloraz containing pesticide composite which comprises oxinecopper, prochloraz and common additives, wherein the pbm (parts-by-mass) ratio of oxinecopper to prochloraz is (30:1)-(1:15), preferably (20:1)-(1:5). After the oxinecopper and the prochloraz are compounded, an obvious synergistic effect is achieved, and the dosages of the effective ingredients of the compounded medicament are significantly less than those of oxinecopper and prochloraz which are used singly. The pesticide composite disclosed by the invention is suitable to be used for preventing and controlling most of fungal diseases, especially apple alternaria leaf spot.

Description

technical field [0001] The invention relates to a pesticide composition, which uses copper quinoline and prochloraz as active ingredients and is suitable for preventing and controlling fungal diseases of crops in agriculture. Background technique [0002] During the growth and development of crops, they are susceptible to various diseases and cause serious damage. For a long time, chemical control has been the main effective means of disease control. However, in recent years, single drug use and unscientific drug use have caused a variety of pathogenic bacteria to develop resistance to the currently used pesticides, such as anthracnose, leaf spot, sheath blight, etc. Resistance to pesticides is very common and has 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 ...
