experiment example 1

[0023] Experimental example 1: Determination of the inhibitory activity of pyrethroid insecticides on D. destructor of potato

[0024] The original drug of pyrethroid insecticides and the original drug of carbofuran were respectively added to Tween-80 with 10 times the total weight of the active ingredients, and then the solvent acetone was added to prepare an emulsifiable concentrate containing 1% by mass volume of the active ingredients. Then dilute with water to the required concentration.

[0025] A PVC pipe with an inner diameter of 15 mm and a height of 50 mm is used, and one end of the pipe is wrapped with 100-mesh nylon gauze. Fill the tube with washed and dried, high-temperature sterilized river sand through a 40-mesh sieve. The emulsifiable oil was prepared with water to make 3.5mL of liquid medicine containing three concentrations of 10, 1, and 0.1μg / mL, and added dropwise to the upper end of the tube. After 2 hours, when the liquid medicine diffused, 0.5mL of susp...

[0032] Experimental example 2: Determination of the effect of deltamethrin on the movement of D. destructor in potatoes

[0033] The impact of deltamethrin on the movement of D. destructor potato was determined by the sand column method, and the specific method was the same as that in Example 1. The experimental results are shown in Table 2, and the experimental results of the control drug are shown in Table 3.

[0040] Experimental example 3: Control effect of deltamethrin on rice root-knot nematode and root-knot nematode incognita

[0041]The original drug of deltamethrin and the original drug of carbofuran were respectively added to Tween-80 with 10 times the total weight of the active ingredients, and then the solvent acetone was added to prepare an emulsifiable concentrate containing 1% by mass volume of the active ingredients, which was then used in the experiment Dilute with water to desired concentration.

[0042] The detection method is: first put the diseased soil containing rice root-knot nematode or incognita into the plastic pot, add deltamethrin, avermectin and carbofuran according to the ratio in Table 6, and make the added The amount of liquid medicine is to make the water content of the diseased soil of rice root-knot nematode 50%, and the water content of the diseased soil of root-knot nematode incognita to be 30%. Put the newly germinated rice seeds or transplant 40-...

Abstract

The invention relates to pyrethroid pesticide and a composition for preventing the plant nematodiasis. The active component for killing the nematode is deltamethrin, composition of deltamethrin and abamectin or composition of deltamethrin and carbofuran. The deltamethrin has a good preventing effect for the plant nematode such as the ditylenchus destructor throne, heterodera elachista, meloidogyne incognita chitwood and rice root-knot nematode and can prevent the infection of the nematode on the host plant, after compounding the deltamethrin and the abamectin and compounding the deltamethrin and the carbofuran, the synergism is obvious, and the control efficacy can be improved.

Description

technical field [0001] The present invention relates to the application of a kind of pyrethroid and its composition as nematicides, more specifically, relates to the application of deltamethrin and the composition containing deltamethrin and abamectin in preventing and treating plant nematode diseases . Background technique [0002] Nematode disease is a worldwide problem. According to statistics, the annual loss of crop production worldwide due to nematode damage is about 100 billion US dollars. Most of the most serious damage to crops are resident internal parasitic nematodes, especially root-knot nematodes (Meloidogyne spp.), cyst nematodes (Heterodera spp.), short-bodied nematodes (Pratylenchus spp.) and smooth-edged nematodes. , of which root-knot nematodes topped the list. Due to the concealment of its hazards, people often underestimate the losses caused by nematodes. After crops, vegetables, and fruit trees are damaged, the production can generally be reduced by 1...
