Embodiment 2

[0053] Test target: brown planthopper Adults and nymphs of brown planthopper were collected for the rice experiment field of Jiangsu Academy of Agricultural Sciences, and they were reared with rice seedlings indoors.

[0054] Cultivation conditions: The temperature of the insect culture room is 28±2°C, the relative humidity is above 70%, and the light is 14 hours a day. The rice seeds were sown in a 20cm×30cm plastic box after germination, and when the rice seedlings grew to more than 10cm, the brown planthopper nymphs were raised until adults. Put the potted rice plants without eggs of rice planthoppers into a 30cm×30cm×50cm insect cage, pick up the egg-bearing female adults and lay eggs for 2 to 3 days, take out the rice seedlings, and replace them with rice plants without eggs. Inside the wormer box. After the brown planthopper eggs on the rice plants taken out from the insect rearing box hatched, 3-day-old brown planthopper nymphs were taken each time for testing.

Embodiment 3

[0061] Test target: diamondback moth (Plutella xylostella L.). A number of advanced larvae and pupae of diamondback moth were collected in cabbage vegetable fields in the suburbs of Nanjing, and they were bred indoors with cabbage.

[0062] Cultivation conditions: the temperature of the insect culture room is 26±2°C, the relative humidity is about 70%, and the light is 14h. Put potted cabbage without eggs in a 30cm×30cm×50cm insect cage, put diamondback moth pupae into the insect cage, let them emerge, mate and lay eggs on the cabbage, take out the insect culture two days later The cabbage in the cage is put into another insect cage for hatching and raising, and the potted cabbage without worm eggs is put into the insect cage with pupae and adults for continued oviposition. The 2nd instar early Plutella xylostella larvae were taken each time for the test.

[0063] Test treatment: conduct preliminary test first. According to the results of the preliminary test, 6 different c...

preparation example 2——20

[0080] 3.2. Preparation 2——20% Chlorthialine-Metaflumizone Suspending Concentrate

[0081] The content of each component (by weight) is: chlorothialine 5%, metaflumizone 15%, dispersant sodium lauryl alcohol polyoxyethylene ether sulfate 10%, thickener hydroxymethyl cellulose 3%, stable Agent butyl glycidyl ether 2.5%, antifoaming agent silicone oil 1%, penetrating agent silicone 2%, antifreeze agent glycerin 3%, deionized water to make up 100%.

[0082] First add chlorothialine and metaflumizone into deionized water, then add dispersant, thickener, stabilizer, defoamer, penetrant, antifreeze, mix in the mixing tank, and then carry out a colloid mill, two A sanding process, so that the particle size is all below 5μm.

[0083] 3.3. Preparation 3——25% Chlorthiazolin-Metaflumizone Suspending Concentrate

[0084] The content of each component (by weight) is: chlorothialine 5%, metaflumizone 20%, dispersant alkylphenol polyoxyethylene ether sulfonate 10%, thickener polyvinyl alco...

Abstract

The invention relates to a broad-spectrum insecticidal composition for crops, a pesticide preparation, a preparation method and an application. The composition is composed of imidaclothiz and metaflumizone mixed according to the weight ratio of 20:1-1:50. The pesticide preparation consists of 10-50% of the composition and the balance auxiliary components. According to the invention, a synergistic effect among the components is obvious; insecticidal spectrum can be broadened; dosage of active components can be reduced; frequency of drug administration is minimized; costs and labor are saved; and environmental pollution is also reduced.

Description

technical field [0001] The invention relates to a broad-spectrum insecticidal composition for crops, a pesticide preparation based on the composition, a preparation method of the pesticide preparation, and an application of the pesticide preparation, belonging to the technical field of compound pesticides. Background technique [0002] According to the applicant's knowledge, after the banning of highly toxic and high-residue pesticides, the repeated use of conventional pesticides over a long period of time has led to increasingly serious pest resistance, and the types of resistant pests are also increasing, and it is easy to cause excessive pesticide residues in agricultural products and The pollution of the environment and the increase in the cost of pesticides for farmers. Therefore, the research and development of new types of compound pesticides that are safe, efficient, and have different mechanisms of action and synergistic effects will not only help to expand the inse...
