Ultra low volume liquid formulation containing spirodiclofen

Abstract

The invention discloses an ultra low volume liquid formulation containing spirodiclofen. The ultra low volume liquid formulation is prepared by the following steps of: using spirodiclofen or a complex formulation compounded by spirodiclofen and an active component B as an active component and adding a surfactant, a solvent and a cosolvent. The active component B is any one selected from the group consisting of propargite, avermectin, acetamiprid, imidacloprid, nitenpyram, thiamethoxam and beta-cypermethrin. The liquid formulation contains the following components of: by weight, 0.5-10% of spirodiclofen, 0-15% of the active component B, 1-15% of an auxiliary agent and the balance being the solvent supplied to 100%. The invention has advantages of fast effectiveness, good drug effect, long effective duration, no water, less application amount and low application cost.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to a method containing spirodiclofen or spirodiclofen and propargite, abamectin, acetamiprid, imidacloprid, nitenpyram, thiamethoxam, and beta-cypermethrin, one of which is Ultra-low volume liquid formulation of a binary composition of active ingredients. Background technique [0002] Ultra-low volume liquid is a pesticide formulation suitable for ultra-low-volume spraying. Ultra-low-volume spraying is an advanced new technology for pesticide application with the emergence of ultra-low-volume spraying equipment, because its droplets are uniform in fineness The oily mist droplets are easy to adhere to the crops, and the loss of mist droplets is small, so the utilization efficiency of pesticides is high. Compared with conventional spray-applied pesticide formulations, it has the following characteristics: [0003] 1. The spray volume is low, 60-330mL / mu, which is one h...

Problems solved by technology

But there is no ultra-low volume solution of spirodiclofen coming out

Secondly, propargite, abamectin, acetamiprid, imidacloprid, nitenpyram, thiamethoxam, and beta-cypermethrin of the active component B are commonly available in the market as emulsifiable concentrates, suspension concentrates, microemulsions, wettable powders, water Dispersible granules, the long-term single and large-scale use of this type of active ingredient makes the pests develop strong resistance, which is not conducive to the further improvement of the drug effect, and increases the difficulty of pest control. It is necessary to increase the dosage and spraying times. Increased labor intensity and increased prevention and control costs

In addition, the large-scale use of pharmaceuticals will inevitably lead to an increase in the amount of residues in the environment, causing certain pollution to the environment.
