Problems solved by technology

[0005] However, with the continuation of chemical control, the increase in the use of pesticides, and the unscientific use of pesticides, the resistance of pests is becoming more and more serious, and the types of pests that develop resistance are increasing, especially Lepidoptera pests that are seriously harmful to agricultural production. The degree of resistance development is relatively high, and the resistance of agricultural pests has become a global problem
At the same time, the high-intensity use of pesticides leads to excessive pesticide residues in agricultural products, environmental pollution, and increased pesticide costs for farmers, which is not conducive to the sustainable development of agriculture.

Embodiment 1

[0054] The research of the composite performance of embodiment 1 clothianidin and diazinon

[0055] Indoor toxicity bioassay was carried out by dipping method, clothianidin and diazinon were compounded according to a certain ratio, and the experimental detection of pest control was carried out. The specific method was: take the drug to be tested, mix planthoppers and dichemical After the borers were immersed in the medicinal solution for 10 seconds, the excess medicinal solution was sucked up with filter paper, and the tested insects were transferred to rearing under normal conditions. Each treatment was repeated 4 times, with 20 worms soaked each time, and the treatment without chemical was set. as comparison.

[0056] See Table 1 for the LD50 test results of the tested drugs against rice planthoppers and stem borers. According to the co-toxicity coefficient, evaluate the interaction of the two single agents in the insecticidal composition provided by the invention, the eval...

Embodiment 2

[0060] Example 2 Containing 0.5% clothianidin·diazinon-sustained-release medicinal fertilizer granules

[0066] Filler: Filler is clay, make up to 100%.

[0067] Preparation method: first weigh each component according to the formula, and set aside. Mix the cross-linked starch and water at 50°C and heat for 60 minutes, add clothianidin and diazinon...

Embodiment 3

[0068] Example 3 Containing 0.4% Clothianidin Diazinon-sustained-release medicinal fertilizer granules

[0069] The formula is as follows, by mass percentage:

[0070] Insecticide composition: Clothianidin 0.3%; Diazinon 0.1%;

[0071] Active ingredients of fertilizer: N content 35%, P content 5%, K content 10%, Ca content 1.5%, Mg content 0.3%, S content 0.5%, Zn content 1.5%, B content 0.3%. Among them, N element is provided by urea; P is provided by superphosphate; K is provided by potassium sulfate; Mg and S elements are provided by magnesium sulfate heptahydrate, Ca is provided by slaked lime, and B is provided by boric acid.

[0072] Sustained release material: Gum Arabic 4%;

[0073] Auxiliary: 4% cross-linked starch;

[0074] Filler: The filler is a mixture of clay and diatomaceous earth (the mass ratio of clay to diatomite is 1:1), which is supplemented to 100%.

[0075] Preparation method: first weigh each component according to the formulation method, and set as...

Abstract

The invention relates to the technical field of pesticides, and particularly relates to an insecticide composition as well as application and a preparation thereof. The insecticide composition is prepared from clothianidin and diazinon. The insecticide composition has a remarkable synergetic effect. A sustained-release insecticide-fertilizer provided by the invention has a good sustained-release effect, has double effects of killing insects and fertilizing, is smaller in usage as compared with a single insecticide agent, and can be used for greatly improving the utilization and use effect of pesticide and fertilizer and reinforcing the insecticide effect and fertilizer effect.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an insecticidal composition and its application and preparation. Background technique [0002] Rice is native to tropical Asia, and after being widely planted in China, it gradually spread to all parts of the world. The fruit of paddy rice is rice paddy, and paddy paddy is called rice, fragrant rice, rice after shelling. Nearly half of the world's population feeds on rice. In addition to being edible, rice can also be used as industrial raw materials for wine making and sugar refining, and rice husk and rice straw can be used as feed. [0003] In the rice planting process, common pests mainly include Homoptera pests (typical pests include rice planthopper, whitefly, etc.) and Lepidoptera pests (typical pests include rice stem borer, rice leaf roller, etc.). Among them, rice planthoppers damage rice and other crops by piercing and sucking plant juice, causing their growth to...
