Method for preventing and treating Rhbdophaga salics Schrank for wickerwork

Abstract

The invention belongs to the technical field of willow planting for wickerwork, and particularly relates to a method for preventing and treating Rhbdophaga salics Schrank for wickerwork. The method includes cottage management and prevention and treatment management. An insecticidal liquid comprises, the following raw materials in parts by weight, 24-28 parts of burkhoderia pseudomallei fermentation material, 6-10 parts of compound peptide nucleic acid, 3-5 parts of berberine, 1-3 parts of p-nitrobenzyl alcohol, 0.2-0.6 parts of emulsion stabilizer, and 100 parts of complex solvent. Compared with the prior art, the method has the following advantages that after the burkhoderia pseudomallei is fermented and then reacts with the compound peptide nucleic acid, berberine and p-nitrobenzyl alcohol, so that the obtained insecticidal liquid has a good prevention and treatment effect on Rhbdophaga salics Schrank of salix integra, and the percentage of damaged trees can be greatly reduced by reasonable management. The damaged tree crowns can be recovered, and the method is safe and harmless to the growth of salix integra. The method is remarkable in economic benefit and suitable for popularization and application.

Description

technical field [0001] The invention belongs to the technical field of willow bark for wicker planting, and in particular relates to a method for preventing and controlling gall and insect pests of willow bark for willow weaving. Background technique [0002] Willow is a perennial shrub with deciduous clusters. It is the raw material for craft willow weaving. The products weaved by willow can be exported in large quantities every year to earn foreign exchange. The gall midge of willow belongs to the family Diptera and is the main pest that harms willow along the Huaihe River. The perennial planting area of ​​willow willow in the area around the lake is more than tens of thousands of hectares, and the annual occurrence area of ​​willow gall midge accounts for 30-40% of the planting area, and the annual recurrence rate reaches more than 80%, which seriously restricts the development of willow weaving industry. At present, domestic and foreign There are few research materials o...

Problems solved by technology

[0002] Willow is a perennial shrub with deciduous clusters. It is the raw material for craft willow weaving. The products weaved by willow can be exported in large quantities every year to earn foreign exchange. The gall midge of willow belongs to the family Diptera and is the main pest that harms willow along the Huaihe River. The perennial planting area of ​​willow willow in the area around the lake is more than tens of thousands of hectares, and the annual occurrence area of ​​willow gall midge accounts for 30-40% of the planting area, and the annual recurrence rate reaches more than 80%, which seriously restricts the development of willow weaving industry. At present, domestic and foreign There are few research materials on the gall midge, and it is obtained through field control experiments that 20% acetamiprid SL is the best insecticide for the control of the gall midge, followed by 10% imidacloprid WP, ​​40% chlorpyrifos EC and 25% thiophene In actual production, although the above pesticides have a better control effect on gall midges, it is difficult for persecuted willows to recover. Therefore, further research should be carried out on how to quickly control gall midges and management methods
