Embodiment 1

[0046] Embodiment 1: 51% bifenthrin·profenofos emulsion in water

[0047] 1g bifenthrin, 50g profenofos, 16g N-methylpyrrolidone, 5g vegetable oil, 2g calcium alkylbenzenesulfonate, 5g phenethylphenol formaldehyde resin polyoxyethyl ether, 4g ethylene glycol, 0.4g silicone compound, 0.1g xanthan gum, 0.4g magnesium aluminum silicate, and water to make up to 100g to prepare 51% bifenthrin·profenofos emulsion in water.

Embodiment 2

[0048] Embodiment 2: 20% bifenthrin profenofos microemulsion

[0049] 15g bifenthrin, 5g profenofos, 12g vegetable oil, 3g N-methylpyrrolidone, 7g phenylphenol polyoxyethyl ether phosphate, 6g nonylphenol polyoxyethylene ether, 3g Span 80, 5g ethylene glycol , 0.4g silicone compound, water to make up to 100g, the emulsifier and water are mixed to make the water phase, and then the original drug dissolved in the solvent is added to the water phase under stirring to make 20% bifenthrin acrylic acid bromide microemulsion.

Embodiment 1-2

[0050] Carry out 1-2 field experiments on controlling rice planthoppers;

[0051] Control agent: 40% profenofos emulsifiable concentrate; 25 g / L bifenthrin emulsifiable concentrate.

[0052] Table 2 Field efficacy test of treatment chemicals on rice planthopper control

[0053]

[0054] It can be seen from Table 2 that the combination of bifenthrin and profenofos has a good control effect on rice planthoppers, the control effect is better than that of a single agent, and it has better quick-acting and long-lasting effects. Within the range, it is safe for rice, and the preparation of the invention has good control effect on rice leaf roller, rice stem borer and rice stem borer.

Abstract

The invention relates to a pesticidal composition containing bifenthrin and profenofos, which is mainly characterized by containing 1 to 20 percent of bifenthrin, 2 to 50 percent of profenofos, an aid and other excipients, and being prepared into micro-emulsion and aqueous emulsion. The pesticidal composition is used for controlling aphid, whiteflies, plant hopper, cotton bollworm and plutella xylostella on commercial crops and vegetables.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an insecticidal composition of profenofos and bifenthrin, which is used for preventing and controlling pests on fruit trees, economic crops and vegetables. Background technique [0002] In recent years, the direction of pesticide development is to embody high efficiency, low toxicity, low residue and no pollution. The specific performance is the pursuit of "three highs", that is, (1) high safety, which not only requires low toxicity, low residue, and pollution-free; (2) high biological activity; (3) high selectivity. Therefore, continue to improve the performance of the current pesticide products to meet the requirements of high efficiency, low toxicity and no pollution. Therefore, choosing a compound mixture of pesticides has become the current first choice and an effective way. By adjusting the ratio of different pesticides, the best synergistic effect can be ob...
