Embodiment 2

[0049] Test target: brown planthopper (Nilaparvata lugens ) collected brown planthopper adults and nymphs from the rice experiment field of Jiangsu Academy of Agricultural Sciences, and reared them with rice seedlings indoors.

[0050] 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 test...

Embodiment 3

[0057] 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.

[0058] 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.

[0059] Test treatment: conduct preliminary test first. According to the results of the preliminary test, 6 different c...

Abstract

The present invention relates to a pesticide insecticidal composition, a pesticide preparation and application thereof. The composition is composed of nematodes flufiprole and imidaclothiz in a mass ratio of 1:80-30:1. The pesticide preparation contains 10-50% of the pesticide insecticidal composition and the balance of auxiliary components. The components of the pesticide insecticidal composition are remarkable in synergy effect and can broaden the insecticidal spectrum, so that the dosage of the effective components can be reduced, the dosing number of times can be reduced, the cost is lowered, the labor is saved and meanwhile, the environmental pollution is further alleviated.

Description

technical field [0001] The invention relates to a pesticide insecticidal composition, its pesticide preparation and application, and belongs to the technical field of binary compound pesticides. Background technique [0002] As far as the applicant knows, with the withdrawal of highly toxic and high-residue pesticides from the market and the restriction and prohibition of the use of fipronil, which is highly harmful to aquatic organisms and the environment, it has become a priority to find safe, efficient, and low-toxic pesticides to meet the needs of agricultural production. Very pressing question. However, long-term single and repeated excessive use of pesticides 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 environmental pollution, and increase the cost of pesticides for farmers. Therefore, the research and development of new types of...
