Embodiment 1

[0017] Example 1: Joint toxicity determination of fluoride and chlorfenapyr to diamondback moth

[0018] The test agent used 98.5% of the original drug of fluoride and 95% of the original drug of chlorfenapyr.

[0019] Put the Plutella xylostella larvae collected in the field into the prepared cabbage seedlings. After the larvae pupate, collect the pupae into a petri dish lined with moisturizing filter paper, put them into an egg-laying cage to let them emerge, and then put the whole plate of cabbage Put the seedlings into the egg-laying cage to let the Plutella xylostella larvae lay eggs. When the number of eggs dropped by each cabbage seedling reaches about 500, take out the cabbage seedling tray and put it in an artificial climate box [temperature: 24-26°C; relative humidity 70%- 80%; light: 14(L):10(D)], the eggs were hatched, and the larvae were reared until the third instar.

[0020] Determination is carried out by the poisoned leaf method: the leaf butterfly is punched...

Embodiment 2

[0029] Example 2: 20% fluorinyl urea·chlorfenapyr wettable powder

[0030]

[0031] The above-mentioned materials are coarsely pulverized in proportion, then put into a mixer and mixed uniformly, and then jet pulverized to obtain a 20% wettable powder of fluorinyl urea·chlorfenapyr.

Embodiment 3

[0032] Example 3: 24% fluoride chlorfenapyr water dispersible granules

[0033]

[0034]

[0035] The above formula is dry crushed, granulated, dried and sieved according to the proportion to prepare the 24% fluoride-chlorfenapyr water-dispersible granule.

Abstract

The invention discloses an insecticidal composition containing novaluron and chlorfenapyr, which contains effective ingredients of the novaluron and the chlorfenapyr with the weight part ratio of 1:5-5:1. The weight sum of the novaluron and the chlorfenapyr is 7%-95% of the composition weight. According to actual needs, the insecticidal composition containing the novaluron and the chlorfenapyr of the invention can be prepared into one of an aqueous emulsion, a micro emulsion, a suspending agent, wettable powder, and a water dispersible granule and be used for the control of agricultural Lepidoptera pests.

Description

technical field [0001] The invention relates to an insecticidal composition containing fluoride and chlorfenapyr, which is used as active ingredients to prevent and control agricultural pests, such as diamondback moth, Spodoptera litura, Leaf tortrix and Beet Spodoptera , armyworm and other Lepidoptera pests. Background technique [0002] The problem of resistance to agricultural pests is a global problem and has always been a key topic of concern to agricultural science and technology workers. With the continuation of chemical pest control year after year, 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 resistant pests are increasing. At the same time, the high-intensity use of pesticides leads to excessive pesticide residues in agricultural products, environmental pollution and increased costs of pesticides for farmers, which is not conducive to the sustainable develo...
