Problems solved by technology

[0016] 1. The work efficiency of the conventional spraying method is low, and the work efficiency per capita is usually only 2-5 mu/day, which is difficult to meet the needs of large-scale planting
[0017] 2. Conventional spraying method needs a lot of water to control diseases and insect pests, usually the water consumption is 450~900L/hm 2 , and in many areas far away from water sources and arid and water-scarce areas, conventional spraying methods are difficult to implement or cannot achieve the desired control effect
[0018] 3. The medicines used in the conventional spraying method have a short duration of action. Since the dosage forms of the medicines used in the conventional spraying method are usually emulsifiable concentrates, water preparations, wettable powders, suspension concentrates, and water-emulsions, there are certain defects in use:
[0019] (1) Due to the addition of a large amount of water for dilution, the concentration of the medicinal solution is very low, and the surface tension is often high. The adhesion, wettability, and permeability on the surface of the crop or target with a w

Abstract

The invention discloses ultralow volume liquid containing spirotetramat, which is prepared by using spirotetramat or a compound of the spirotetramat and an activated ingredient II as an activated ingredient and adding adjuvant and solvent. An activated ingredient B is optional one of etofenprox, efficient cypermethrin, deltamethrin, tolfenpyrad, chlorantraniliprole, flubendiamide, ivermectin, indoxacarb, RH-5849 (1, 2-dibenzoyl-1-tert-butylhydrazine) and tebufenozide. The ultralow volume liquid containing spirotetramat has the advantages of convenience in processing, long-term effect, a target being not easy to resist the pesticide, low environmental pollution, pesticide and water economization, increase of pesticide utilization rate, and can be used for controlling various pests on rice, wheat, vegetables, tobacco plants, tea plants, fruit trees and sugarcanes by means of ultralow volume spray, low volume spray or ultralow volume static spray.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to an ultra-low volume liquid containing spirotetramat. Background technique [0002] At present, for the control of pests that are prone to resistance in agriculture, the main method is to develop new ingredients that have no cross-resistance with existing varieties or the compounding of existing pesticide varieties. The former is due to the high development cost and long cycle required. And the current development speed is far behind the speed of pest resistance. Therefore, it is the best choice to mix existing pesticide varieties with different action mechanisms. If the ratio is reasonable, it can produce a significant synergistic effect, making the field control effect significantly better than the effect of each single agent. Insecticides containing a single active ingredient often have certain defects in the control of agricultural pests. Continuous use for mu...
