example 1

[0021] Experimental agents: 95% dinotefuran (Nanjing Fubang Chemical Co., Ltd.), 95% buprofezin (Nanjing Panfeng Chemical Co., Ltd.) (the same below).

[0022] The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.14-2008", using the leaf soaking method: pick fresh tomato leaves and soak them in the diluted medicinal solution for 10 seconds, take them out, put them in the room to dry, and then Place in a petri dish with a diameter of 9 cm, and put 1 tomato leaf in each petri dish. Gently pick the 2nd instar nymphs of Bemisia tabaci into a petri dish, each dish has 30 nymphs, seal the petri dish with plastic wrap, and pierce several small holes on the plastic wrap to facilitate ventilation. Then they were reared in an incubator with a temperature of 21°C and a photoperiod of 16h:8h (L:D), with clear water as the control, and each concentration was repeated 3 times. After 48 hours, the death situation was checked under a binocular mic...

[0031] Biological Assay Example 2: Indoor Toxicity Test of Rice Planthopper (BPH)

[0032] The test method refers to "People's Republic of China Agricultural Industry Standard NY / T1154.11-2008" and "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006". The rice stem dipping method is used: pull out the strong rice plants from the tillering stage to the early booting stage, wash them, cut them into 15 cm long rooted rice stems, and put them in a group of 3 plants, and dry them in a cool place until there is no water mark on the surface. Soak the rice stems in the diluted medicament for 30 seconds, take them out and dry them, wrap the roots with soaked absorbent cotton and put them in the culture cups, absorb the 3rd instar mid-stage nymphs and put them in the culture cups, 20 heads per cup, put They were raised in an incubator with a temperature of 27°C and a photoperiod of 16h:8h (L:D). Water control, each concentration was repeated 3 times. The number ...

Abstract

The invention discloses a synergia pesticide composition which takes buprofezin and dinotefuran as effective ingredients and the mass ratio of the buprofezin and dinotefuran is 50:1-1:50. The pesticide composition is suitable for rice, cotton, fruit tree, vegetables for preventing various homoptera insect pests such as plant hoppers, leaf hoppers and aleyrodid; the synergia pesticide composition has the advantages that: the control effect including quick action and sustaining action is high, low dose administration and less environmental pollution.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to an insecticidal composition compounded with buprofezin and dinotefuran, which is used for controlling pests harmful to plants. Background technique [0002] Buprofezin (Buprofezin), the chemical name is 2-tert-butylimino-3-isopropyl-5-phenyl-1,3,5-thiadiazin-4-one, and its mechanism of action is to inhibit insect chitin Plasma synthesis and interference with metabolism, resulting in nymph molt deformity or wing deformity and slow death, has a good control effect on nymphs of Homoptera pests such as planthoppers and leafhoppers. Buprofezin has a strong contact effect and stomach toxicity. The disadvantage is that it has no obvious control effect on the adults of Homopteran pests. In addition, it has been found that rice planthoppers and other pests have produced low-medium level resistance to buprofezin (BPH Monitoring of resistance to buprofezin, China Rice Science, 2008, 22(2)), t...
