EXAMPLE 725% Chlorfluazuron aqueous suspension (sample 7)
Adding 25Kg of chlorfluazuron, 1.5Kg of alkylphenol polyoxyethylene, 3Kg of nonylphenol polyoxyethylene phosphate, 1Kg of dioctyl sodium sulfosuccinate, 1.5Kg of magnesium aluminum silicate, 0.15Kg of xanthan gum, 0.3Kg of Kethon, 5Kg of ethylene glycol, 3Kg of Douglas fir 3-O-xyloside, 7Kg of cocamidopropyl-ethylhydroxy-3-sulfopropyl betaine, and water to 100Kg in a mixing kettle, mixing and sanding until 90% volume fraction of solid particles have a particle size of less than 5.0 μm, to prepare 33.5% of oxine-copper suspension (sample 7)
Preparation of 25% aqueous suspension of chlorfluazuron (comparative agent 7-1)
The difference from example 7 is that Douglas fir 3-O-xyloside and cocamidopropyl-ethylhydroxy-3-sulfopropyl betaine are not added.
Contrast agents 7-2: 25% chlorfluazuron aqueous suspension: chlorfluazuron (registration number PD20160409, manufacturer: Ningbo Sanjiang Ying agricultural chemical Co., Ltd.) (commercially available sample 7)
Field efficacy test of sample 7, contrast agent 7-1 and contrast agent 7-2
The test method comprises the following steps: the field efficacy test is carried out according to GB/T17980.13-2000 field efficacy test criterion (I) that the pesticide prevents Lepidoptera larva of cruciferous vegetables.
TABLE 1 field drug effect test results
As is clear from the test results, example 7 was 10.4%, 9.1%, 93.8%, 93.4%, and 93.8% higher than comparative agent 7-1, comparative agent 7-2, Douglas fir 3-O-xyloside, Cocamidopropyl-ethylhydroxy-3-sulfopropyl betaine, Douglas fir 3-O-xyloside, and Cocamidopropyl-ethylhydroxy-3-sulfopropyl betaine, respectively. Has obvious synergistic effect of suspending preparation in raising pesticidal effect.
Test sample of aqueous suspension, contrast agent, and commercial contrast agent penetration contrast test
Determination of the permeability: according to a wetting method for measuring the permeability of a textile auxiliary of a GB5557-85 surfactant, a canvas settlement method is adopted to measure the time required by a circular canvas sheet to contact 200 times of a diluent of a suspending agent preparation until settlement starts.
The results of the permeability tests are shown in Table 1
Note: the shorter the wet settling time in table 1 indicates the better the liquid permeability.
It can be seen from Table 1 that the permeability of the aqueous suspension samples was generally better than that of the prepared and commercially available control agents.
Test for surface tension measurement of example sample, preparation of contrast agent, and commercial contrast agent.
Measurement of surface tension: referring to NY/T1860.31-2016 physicochemical Properties of pesticides determination rules, section 31: surface tension of aqueous solution the surface tension of 200-fold and 500-fold dilutions was measured using a fully automatic surface tensiometer, and each aqueous solution was tested five times, and the average of five times was taken as the measurement result.
The results of surface tension measurements of the sample, the prepared contrast agent and the commercial contrast agent are shown in Table 1
It can be seen from table 1 that the surface tension levels of the example samples are generally lower than those of the prepared and commercially available control formulations, resulting in better wetting.
In conclusion, the synergist improves the permeability of the preparation in the oil-based pesticide, reduces the surface tension of the preparation, improves the volatilization resistance of the oil-based preparation, and has obvious synergistic effect on the oil-based preparation.
