Embodiment 1

[0030] Embodiment 1 0.5% bifenazate ultra-low volume liquid

[0031] According to the following weight ratio:

[0032]

[0033] Preparation method: at normal temperature and pressure, weigh the raw materials according to the weight percentage, first put the solvent into the reaction kettle, put in the active ingredients at a stirring speed of 60 rpm, and put in the co-solvent and the surface after the active ingredients are completely dissolved. The active agent was stirred for 60 minutes to obtain a homogeneous and transparent oily product.

Embodiment 23

[0034] Embodiment 23% bifenazate ultra-low volume liquid

[0035] According to the following weight ratio:

[0036]

[0037] Preparation method: at normal temperature and pressure, weigh the raw materials according to the weight percentage, first put the solvent into the reaction kettle, put in the active ingredient at a stirring speed of 80 rpm, and put in the co-solvent and the surface after the active ingredient is completely dissolved. The active agent was stirred for 50 minutes to obtain a uniform and transparent oily product.

Embodiment 35

[0038] Embodiment 35% bifenazate ultra-low volume liquid

[0039] According to the following weight ratio:

[0040]

[0041] Preparation method: at normal temperature and pressure, weigh the raw materials according to the weight percentage, first put the solvent into the reaction kettle, put in the active ingredients at a stirring speed of 100 rpm, and put in the co-solvent and the surface after the active ingredients are completely dissolved. active agent, stirred for 40 minutes to obtain a homogeneous and transparent oily product.

Abstract

The invention discloses an ultralow-volume liquid containing bifenazate. According to the 100% ultralow-volume liquid, an active component I bifenazate or an active component I bifenazate and an active component II is regarded as an active component, and the balance includes a surfactant, a cosolvent and a solvent; the active component II is any one of propargite, abamectin, acetamiprid, imidacloprid, nitenpyram, thiamethoxam and beta-cypermethrin; and according to the percentage by weight, the 100% ultralow-volume liquid containing the bifenazate is composed of 0.5-10% of the active component I, 0-15% of the active component II, 1-15% of the surfactant and the balance of the cosolvent and the solvent. The ultralow-volume liquid containing the bifenazate, disclosed by the invention, has the advantages of high effect, capability of saving pesticide during a spraying period, good drug effects, long persistence, low preventive treatment cost, synergistic effects and the like.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to an ultra-low volume liquid containing bifenazate. 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 hundredth of the conventional spray volume; [0004] 2. The droplets are fine, and the particle size range of ultra-low volume liquid is 20-100 μm, while the diameter of conventional droplets is 200-600 μm. The cove...
