Embodiment 1

[0058] Embodiment 1: 5% tolfenpyrad · spinosad microemulsion (1: 1)

[0059] 98% Fenpyrad 2.55g

[0060] 90% Spinosad Technical 2.78g

[0061] Xylene (solvent) 10 grams

[0062] Tristyrylphenol polyoxyethylene polyoxypropylene ether (emulsifier) ​​5g

[0063] Calcium dodecylbenzenesulfonate (emulsifier) ​​5g

[0064] Water to make up to 100g.

[0065] The original drug, solvent and emulsifier are added together to dissolve into a uniform oil phase; under high-speed stirring, the oil phase is mixed with water to prepare a 5% tonamiprole-spinosyn microemulsion.

[0066] This embodiment is applied to the prevention and treatment of eggplant thrips. Dilute and spray 5% pyrenpyrid spinosad microemulsion according to the active ingredient dosage of 30 g / ha, and the control effect on eggplant thrips 2 days after the medicine is 92.2%; gram / ha diluted spraying, the control effect 2 days after the application was 70.4%; 2.5% spinosad suspension was diluted and sprayed according t...

Embodiment 2

[0067] Embodiment 2: 22% tolfenpyrad · spinosad suspension concentrate (10: 1)

[0068] 98% Fenpyran 20.41g

Abstract

The invention discloses a synergistic pesticide composition which is characterized in that the effective components thereof are tolfenpyrad and spinosad. The pesticide composition has excellent prevention and treatment effects on agricultural lepidoptera, thysanoptera, diptera, coleopteran and homoptera pests.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a synergistic pesticide composition containing tolfenpyrad. Background technique [0002] At present, in order to delay the occurrence and development of resistance, improve drug efficacy, reduce costs, expand the control spectrum, and reduce the frequency of application, people often use the two agents in a mixed manner. After different pesticides are mixed, they usually show three types of effects, namely additive effect, synergistic effect and antagonistic effect, but the specific effect can only be known through a large number of experiments. Under normal circumstances, farmers' tank mixing is only based on subjective judgments, without scientific basis. Unreasonable mixing of pharmaceuticals will not produce complementary advantages, but may also cause serious side effects. [0003] Tolfenpyrad: English common name tolfenpyrad, chemical name 4-chloro-3-ethyl-1-methyl-N-[4-(p-tolyl...
