Embodiment 1

[0036] Bioassay Example 1: Indoor Combined Toxicity Determination of Nitrilofenac and Flumefenac against Citrus Red Spiders

[0037] Test insects: citrus red spider nymphs collected in the field and bred indoors were selected.

[0038] Test reagents: 96% fenpyroxifen technical and 97% flufenox technical.

[0039] The test method adopts the leaf butterfly spray method, and the specific operation method is as follows:

[0040] Select healthy citrus leaves, use a hole punch to make leaf butterflies, place a wet sponge block in a petri dish, put filter paper on it, put leaf butterflies on the filter paper, put 2 leaf butterflies on each plate, and select healthy, aged leaves. Consistent citrus red spider nymphs were inoculated on leaf butterflies, 20 per leaf butterfly.

[0041]Place the petri dish connected with the leaf butterfly under the potter spray tower, spray under 50PSI pressure, the spray volume is 1ml, take out the petri dish after settling for 1min, and then put the ...

Abstract

The invention relates to a synergetic acaricidal composition containing cyenopyrafen and flutenzine. The weight ratio of the cyenopyrafen to the flutenzine is (20:1)-(1:20), and the sum of the weight of the cyenopyrafen and the weight of the flutenzine accounts for 5%-80% of the synergetic acaricidal composition in percentage by weight. According to the invention, the effective components of the cyenopyrafen and the flutenzine are compounded, so that the synergetic acaricidal composition has an obvious synergetic effect, and has an excellent control effect on various acarine pests on crops, flowers and plants, such as fruit trees, vegetables, cotton and tea trees. According to the invention, the control effect is improved, and the usage amount of agricultural chemicals is reduced, so that the cost is reduced, the environmental pollution is reduced, the resistance management to the pest mites is facilitated, and the synergetic acaricidal composition has higher economic benefits and social benefits for popularization and application.

Description

technical field [0001] The present invention relates to a pesticide and acaricidal composition, which is used for preventing and controlling agricultural pest mites, using fenpyroxifen and fenflumezine as active ingredients. Background technique [0002] Cyenopyrafen: a new type of pyrazole acaricide, the mechanism of action is that the agent is activated to produce activity by metabolizing into a hydroxyl form, which inhibits mitochondrial cytotoxicity by disrupting complex II in the respiratory electron transport chain. It is mainly used to control various harmful mites on fruits, vegetables and tea such as eggplant, pepper, cucumber, pear, strawberry, citrus, etc. It has good quick-acting and long-lasting effect. effectiveness. [0003] Flufenzine: It has strong contact killing effect, strong knockdown power, and is effective against adult mites, nymphs, young mites and eggs; against citrus panclaw mites, rust mites, tea yellow mites, and cinnabar spider mites And two-s...
