Problems solved by technology

[0004] The large-scale use of single agents and conventional compound preparations for many years has led to an increase in the resistance of such pesticides. Due to the increase in the cost of promoting and using new pesticide products, the production costs of growers have also increased. How to develop the potential value of old products , making it continue to play a greater role is a project worth studying,

Embodiment 1

[0018] Example 1: Determination of indoor toxicity of pyraclostrobin and quinoline copper in different proportions against grape downy mildew

[0019] Test method: The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1156.2-2006". First, set 5 different concentration gradients for the single agent and each mixed agent (on the basis of the preliminary test results, according to different drug combinations and ratios, the concentration gradient settings are also different, and the bacteriostatic rate is between 5% and 90%) It is set according to the geometric series within the range). Set water control group, repeated three times. Using the mycelium growth rate method, the cultured pathogenic bacteria were cut out from the edge of the colony with a 5mm diameter punch under aseptic conditions, and the bacteria cake was connected to the center of the medium plate with different drug concentrations with an inoculation needle. With the silk ...

Embodiment 2

[0027] Embodiment 2: 20% pyriquine suspension concentrate, water dispersible granule etc. to the field efficacy test of grape downy mildew

[0028] pyraclostrobin 5%, quinolinone 15%, sodium lauryl sulfate (surfactant) 2%, white carbon black (filler) 4%, sodium lignosulfonate (dispersant) 5%, Bentonite (filler) makes up to 100%. Dry pulverize, granulate, dry and sieve the above formula in proportion to prepare 20% pyraclostrobin·quinolinone water dispersible granules.

[0029] pyraclostrobin 5%, quinolinone 15%, sodium methylnaphthalene sulfonate formaldehyde condensate (dispersant) 5%, 0203B (surfactant) 6%, white carbon black (filler) 5%, silicon Magnesium aluminum (suspending agent) 0.4%, ethylene glycol (antifreeze) 3%, tributyl phosphate (defoamer) 1.5%, deionized water to make up to 100%. The above formula is pre-crushed according to the proportion, then added to a sand mill for grinding, and then prepared after high-shear mixing to prepare a 20% pyraclostrobin quinoli...

Embodiment 3

[0037] Example 3: Field efficacy test of 20% pyraclostrobin quinolinone water dispersible granules on grape downy mildew

[0038] Test location: The test is located in the grape growing area of ​​Ningxia. The soil quality is sandy loam, the fertility is middle to high, and the management level is good.

[0039] Control object: Grape downy mildew

[0040] Treatment setting and drug application establish 4 treatments altogether, wherein, 3 medicaments are handled, and 1 clear water control is handled, and test medicament is as follows: the water dispersible granule that embodiment 2 prepares, 30% quinoline copper water dispersible granule, 20 % pyraclostrobin water dispersible granules. Each treatment was repeated 4 times, a total of 16 plots, each with an area of ​​15m 2 , 10 grape vines were planted in each plot, and the plots were randomly arranged in blocks. Except for chemical treatment factors, other management measures were the same.

[0041] The condition of grape downy...

Abstract

The invention relates to a sterilizing composition containing pyraclostrobin and quinolinone, wherein the mass part ratio of the pyraclostrobin to the quinolinone is (1-20):(30-1). The sterilizing composition is suitable for preventing and treating plasmopara viticola. The pyraclostrobin and the quinolinone are mixed to achieve an obvious synergistic effect, the use amount of pesticide is reduced,and the sterilizing composition has large economic benefit and social benefit when being popularized and applied.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a bactericidal composition containing pyraclostrobin and quinolinone and its application. Background technique [0002] Pyraclostrobin is a new broad-spectrum fungicide. Mechanism: It is an inhibitor of mitochondrial respiration. That is, it prevents electron transfer in cytochrome synthesis. It has the functions of protection, treatment and leaf penetration. The results of field efficacy tests of pyraclostrobin EC show that it has good control effects on cucumber powdery mildew, downy mildew, banana scab, leaf spot, and sclerotinia. [0003] Quinoline copper (oxine-copper) is a quinoline-type low-toxic protective fungicide, which belongs to an organocopper chelate, with broad spectrum, high efficiency, low residue, safe to use, and good effect on fungal and bacterial diseases. Preventive and therapeutic effects. After spraying, a tight protective film is formed on the plant surface...
