Embodiment 1
[0031] Example 1: After mixing different varieties of pesticides, there are usually three types of effects: additive effect, synergistic effect and antagonistic effect. However, the specific role cannot be determined without a large number of experiments. In order to prevent and control pests that produce resistance in agriculture, the applicant of the present invention firstly passed the indoor biological activity assay test and found that the mixed use of pyraclofen and neonicotinoid insecticides has obvious synergistic effect on pests. This composition was subjected to a quantitative analysis of synergistic effect.
[0032] The test method refers to the "Agricultural Industry Standard of the People's Republic of China NY / T1154.7-2006" for indoor bioassays, and the third instar larvae of Spodoptera litura are selected as the target pests. According to the different ratios of pyraclofen and neonicotinoid insecticides in Tables 1, 2, and 3, different concentrations were prepa...
Embodiment 2
[0042] Example 2: Dissolve 1 kg of pyraclofen and 9 kg of thiacloprid in 15 kg of cyclohexanone, 10 kg of methyl esterified vegetable oil, 4.5 kg of alkylphenol formaldehyde resin polyoxyethylene ether, 4.5 kg of triphenylethyl Add 100 kg of water to the phenol polyoxyethylene polyoxypropylene ether phosphate and 1.5 kg of calcium dodecylbenzenesulfonate emulsifier, and stir evenly to obtain 10% pyraclofen-thiacloprid microemulsion.
Embodiment 3
[0043] Example 3: Dissolve 5 kg of pyraclofen and 15 kg of thiacloprid in 20 kg of octylpyrrolidone, then add 5 kg of styrylphenol polyoxyethylene polyoxypropylene ether phosphate, 2 kg of fatty alcohol polyoxyethylene ether, make up 100 kg with water, stir at high speed for 30 minutes, then add 0.3 kg of polyvinyl alcohol as a thickener, and stir evenly to obtain 20% thiacloprid thiacloprid emulsion in water.
