Technical Field

The invention relates to the field of pesticides, in particular to a dispersing wetting agent composition for improving the tank-mixing compatibility of a pyraclostrobin-oxine-copper suspending agent.

Background

Pyraclostrobin belongs to mitochondrial respiration inhibitor, and acts on cytochrome synthesis process to block normal electron transfer. Has the functions of protection, treatment, leaf penetration and conduction and the like. The results of field efficacy experiments show that the pyraclostrobin missible oil has better control effects on powdery mildew, downy mildew, banana scab, leaf spot, sclerotinia, and the like of cucumbers.

The oxine-copper is a quinoline protective low-toxicity bactericide, belongs to organic copper chelate, has the characteristics of broad spectrum, high efficiency, low residue, safe use and the like, and has good prevention and treatment effects on fungal and bacterial diseases. After the quinoline copper preparation is sprayed, a tight protective medicine film is formed on the surface of a plant, the affinity with the plant is strong, and the rain wash resistance is strong; the medicinal film slowly releases copper ions with bactericidal activity, effectively inhibits the germination and invasion of germs, and thus achieves the purpose of preventing and treating diseases. The oxine-copper preparation is mainly used for preventing and treating diseases caused by bacteria and various fungi, such as downy phytophthora of litchi, black rot of cabbage, downy mildew and anthracnose of grape, downy mildew and anthracnose of various melons, black spot and scab of pear, ring spot, bacterial angular leaf spot of lettuce and the like.

The suspending agent is a viscous suspension preparation with high dispersion degree formed by non-water-soluble solid active ingredients and related auxiliary agents in water, is one of important pesticide preparations with excellent performance in water-based preparations, has the advantages of wettable powder and missible oil, is a new formulation called epoch-making once, develops rapidly at home and abroad, partially replaces wettable powder and missible oil, and is a new formulation with great development prospect.

The pyrazole-oxine copper suspension is a broad-spectrum bactericide, and in practical application, the oxine copper suspension and other medicaments are mixed together and used in a tank, so that the reasonable mixing has the advantages of expanding the prevention and treatment spectrum, increasing the pesticide effect and the like. Despite the advantages of rational pesticide tank-mixing, tank-mixing of oxine-copper presents a number of problems well known to the skilled artisan that arise when oxine-copper formulations are used in combination with other metal ion-containing agents. Due to the self property of the oxine-copper, the oxine-copper preparation has flocculate precipitation when being mixed with a medicament with metal ions such as zinc, manganese, iron and the like, so that the oxine-copper preparation has poor tank mixing compatibility, and the field tank mixing of the oxine-copper is difficult to realize.

It should be noted that, in the present invention, the features of the embodiment, the verification example, and the both may be combined with each other without conflict.

Example 1

A dispersing wetting agent composition comprises naphthalene formaldehyde condensate sulfonate and alkyl naphthalene sulfonate, wherein the mass ratio of the naphthalene formaldehyde condensate sulfonate to the alkyl naphthalene sulfonate is 1: 1.

In order to verify that the naphthalene formaldehyde condensate sulfonate and alkyl naphthalene sulfonate composition can improve the barrel-mixing compatibility of the pyrazole-quinoline copper suspending agent, the method comprises the following steps: weighing the following components according to the proportion of the components in the formula:

adding soft water, alkyl naphthalene sulfonate, antiseptic, defoaming agent, and antifreezing agent in specified amount, and shearing for 3 min. After shearing, adding raw pesticide (pyraclostrobin, oxine-copper) and naphthalene formaldehyde condensate sulfonate, shearing after completely wetting, adding thixotropic agent and thickening agent while shearing, continuously shearing for 15min when no caking and floating materials exist, and sanding after shearing is finished. And (4) after sanding for a certain time, sampling and detecting the particle size, and stopping sanding after the particle size is qualified (less than 5 micrometers). And (4) sampling and analyzing after sanding, and obtaining the required pyrazole-quinoline copper suspending agent product after inspection is qualified. The above-mentioned products that were qualified by the inspection were subjected to a tank-mix compatibility comparative test with a preparation having the same commercially available active ingredient, active ingredient content and formulation (verification examples 1 to 8).

Wherein, the naphthalene formaldehyde condensate sulfonate and alkyl naphthalene sulfonate dispersing and wetting agent composition accounts for 4 percent by weight in the pyrazole-quinoline copper suspending agent; the pyraclostrobin original drug accounts for 10 percent by weight of the pyrazole-quinoline copper suspending agent; the weight percentage of the oxine-copper raw drug in the pyrazole-oxine-copper suspending agent is 30%.

Verification example 1

The 40% pyraclostrobin-oxine-copper suspending agent obtained by the method is subjected to a tank mixing test with a commercially available medium element fertilizer, and the contrast is the commercially available 40% pyraclostrobin-oxine-copper suspending agent. The medium element fertilizer is selected from the medium element fertilizer with the calcium content of 130g/L, the magnesium oxide content of 30g/L, the sulfur content of less than or equal to 30g/L, the chlorine content of less than or equal to 30g/L and the sodium content of less than or equal to 30 g/L. The blank was hard water with 10mL of medium element fertilizer added.

Taking a 3-piece graduated glass graduated cylinder, pouring 230mL of standard hard water into the graduated cylinder, respectively dropwise adding 10mL of medium element fertilizer +10mL of hard water, 10mL of medium element fertilizer +10mL of 40% pyraclostrobin-quinoline copper suspending agent added with a naphthalene formaldehyde condensate sulfonate and alkyl naphthalene sulfonate composition, 10mL of medium element fertilizer +10mL of commercially available 40% pyraclostrobin-quinoline copper suspending agent, starting timing after shaking up and down for 30 times within 1min, standing and observing the phenomenon, recording the time when abnormity starts to appear and measuring the suspension rate according to 4.2 in GB/T14825-2006 after 1 h. On the other hand, the actual spraying effect of the tank mix was examined by carrying out a spraying test with a knapsack sprayer. The results are shown in table 1:

TABLE 1

Obviously, from the verification example 1, the floccule is generated after the commercial 40% pyraclostrobin-oxine-copper SC is mixed with the medium element fertilizer, and the tank mixing compatibility is poor; on the other hand, the suspension rate of 40% pyrazole-quinoline copper SC added with the naphthalene formaldehyde condensate sulfonate and alkyl naphthalene sulfonate composition is still higher after the composition is tank-mixed with a medium element fertilizer, and the suspension rate detection result of the commercially available pyrazole-quinoline copper SC after the tank-mixing is poorer; in the spray test, after the commercially available 40% pyrazole-quinoline copper SC is mixed with a medium element in a tank, generated precipitates can cause the blockage of a spray head and influence the spray quality. That is, when the naphthalene formaldehyde condensate sulfonate and alkyl naphthalene sulfonate composition is 4% by weight in a 40% pyrazole-quinoline copper suspension, the ratio of the particular naphthalene formaldehyde condensate sulfonate and alkyl naphthalene sulfonate is 1:1, the tank-mixing compatibility of the pyraclostrobin-oxine-copper SC with the medium element fertilizer is effectively improved by 40%, and a spray head cannot be blocked in a spray test.

Through a barrel-mixing compatibility test of the pyraclostrobin-oxine-copper suspending agent, the obvious effect of the composition containing the naphthalene formaldehyde condensate sulfonate and the alkyl naphthalene sulfonate on improving the barrel-mixing compatibility of the oxine-copper suspending agent can be obviously seen. Through a barrel-mixing spraying test of a knapsack sprayer, the 40% pyraclostrobin-quinoline copper suspending agent added with the naphthalene formaldehyde condensate sulfonate and alkyl naphthalene sulfonate composition has a good spraying effect and does not block a spray head when being mixed with various pesticide fertilizers and buckets for spraying. Compared with the barrel mixing test and the spraying test of the commercial 40% pyraclostrobin quinoline copper suspending agent, the composition of the naphthalene formaldehyde condensate sulfonate and the alkyl naphthalene sulfonate serving as the wetting dispersant for enhancing the barrel mixing compatibility is feasible to be applied to the 40% pyraclostrobin quinoline copper suspending agent.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention.
