Problems solved by technology

[0003] Pichridam is a new type of neonicotinoid insecticide with high efficiency, low toxicity and broad spectrum. Especially the rice planthopper has a good effect, but due to the increase of drug resistance, it is becoming increasingly difficult to control it with conventional pesticides. Therefore, there is an urgent need to develop new methods and drugs for controlling rice planthopper

Embodiment 1

[0018] Example 1 Toxicity of Pichamid and Antibiotic Insecticide Single Agent and Both Mixtures to Rice Planthopper

[0019] Test object: rice planthopper

[0020] Test method: The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006". The rice planthoppers used in the experiment were pupae of rice planthoppers (BPH) collected from the field. Rice seedlings were used for three generations in the greenhouse, and uniform fourth-instar larvae were selected and placed into rice seedlings (treated with cotton balls for moisturizing). In a petri dish (diameter 12cm), each dish is connected with 30 anesthetized larvae, and each treatment is connected with 4 petri dishes, and the single agent and the mixed agent are sprayed into the petri dish, and each dish is sprayed with 3ml of liquid medicine. After the insects wake up, put the treated petri dish into an incubator at 27°C with a photoperiod of 16h / 8h for cultivation, check the numbe...

Embodiment 2

[0032] An insecticidal composition containing pichridam and an antibiotic insecticide, the insecticidal composition is composed of pichridam and emamectin, and the weight ratio of pichamid and emamectin is 15:1;

[0033] Said composition is made nano microemulsion, specifically comprises the following steps:

[0034] 1) Mix pichampudin, emamectin and zeolite powder and put them in a ball mill, use metal balls with different diameters from 0.5 to 15 mm to make random proportions and use them as grinding balls, and form them to 95% after 24-48 hours of ball milling The above mixture with a particle size of less than 100nm; wherein, the mass ratio of balls to materials is 80:1, the rotational speed of the ball mill is 450 rpm; the mass ratio of pichridam to zeolite powder is 5:1;

[0035] 2) Homogenize the mixture obtained in step 1) to form an insecticidal composition, wherein the homogenization pressure is 1200 bar, and the number of homogenization times is 6;

[0036] 3) Take...

Embodiment 3

[0038] An insecticidal composition containing pichridam and an antibiotic insecticide, the insecticidal composition is composed of pichridam and emamectin, and the weight ratio of pichamid and emamectin is 50:1;

[0039] Said composition is made nano microemulsion, specifically comprises the following steps:

[0040] 1) Mix pichampudin, emamectin and zeolite powder and put them in a ball mill, use metal balls with different diameters from 0.5 to 15 mm to make random proportions and use them as grinding balls, and form them to 95% after 24-48 hours of ball milling The above mixture with a particle size of less than 100nm; wherein, the mass ratio of balls to material is 100:1, the rotational speed of the ball mill is 500 rpm; the mass ratio of pichridam to zeolite powder is 10:1;

[0041] 2) Homogenize the mixture obtained in step 1) to form an insecticidal composition, wherein the homogenization pressure is 15000 bar, and the number of homogenization times is 6;

Abstract

The invention discloses an insecticidal composition containing chloropyridine, which is specially used for preventing and controlling rice planthoppers. The insecticidal composition contains active components and a synergist, wherein the ratio of the active components to the synergist is (95 to 99) to (1 to 5); the active components contain chloropyridine and rotenone in a mass ratio of (75 to 90)to (10 to 15); and the synergist is salicylhydroxamic acid. The insecticidal composition solves the problems of singular action mode, large dosage and easy generation of resistance of a single bactericide, and especially has a good prevent and control effect on the rice planthoppers.

Description

technical field [0001] The present invention relates to the field of plant protection, and in particular to an insecticidal composition specially used for preventing and treating rice planthoppers containing pechram. Background technique [0002] Rice planthopper is one of the main pests of single-season late rice in northern Zhejiang, mainly including brown planthopper, white-backed planthopper and striatellus, among which brown planthopper and brown planthopper pose a serious threat to rice production, causing large-scale The area of ​​rice is dry and lodging, the rice yield is directly lost by 10%-20%, and some fields even fail to harvest. [0003] Pichridam is a new type of neonicotinoid insecticide with high efficiency, low toxicity and broad spectrum. In particular, rice planthopper has a good effect, but due to the increase of drug resistance, it is becoming increasingly difficult to control it with conventional pesticides. Therefore, it is urgent to develop new meth...
