Abstract
Description
TECHNICAL FIELD
[0001] The present application belongs to the field of agricultural pest killing technology, and particularly relates to a killing composition of starose. BACKGROUND
[0002] The starose has one generation per year, and the adult starose generally appears in March to April each year, and bites the bark with mouthparts to lay eggs in the cracks at about 0.5 meters from the ground, one egg per place, and each female starose can lay 70 to 80 eggs, and the eggs are hatched after about 7 days. After hatching, the larvae first feed around the inner side of the bark, and then feed on the wood, causing a number of tunnels, and mature in the hole. Wood chips and insect feces can be found at the base of the damaged plant from the tunnel, and the damaged leaves are yellow and withered, the tree is weak, and finally dies.
[0003] The existing insecticides for the starose mainly include dichlorvos, deltamethrin, etc., and are mainly single use. When used, the following problems exist: the dichlorvos has a short effective period, is highly toxic to humans and animals, and is highly toxic to pests such as bees and birds, and after use, secondary pests may break out; and the deltamethrin has a single mode of action, and long-term use can easily lead to the development of resistance of the starose. SUMMARY

[0027] The active ingredients used in this application are: 77.5% dichlorvos emulsifiable concentrate, 8% cypermethrin emulsifiable concentrate, and 10% thiocyanate suspension, all of which are commercially available products.
[0028] When using, first take the appropriate amount of water according to the required concentration of each active ingredient and the amount of solution to be used, and divide the water into two equal parts; add disodium EDTA to one part and stir until completely dissolved, then add sodium citrate and continue stirring until completely dissolved; then add hydroxyl polyoxyethylene-polyoxypropylene block copolymer and continue stirring until completely dissolved; then add Tween-80 and continue stirring until completely dissolved; then add sodium lignosulfonate and thiotetracycline at the same time and continue stirring until completely dissolved; then add cypermethrin and continue stirring until completely dissolved; then add dichlorvos stock solution and continue stirring until completely dissolved; finally, add the other part of water and stir until well combined.
