Abstract

The invention provides a low-volume spray containing emamectin benzoate and dinotefuran, relating to pesticides. The spray comprises the following raw materials by mass percent: 1-10% of emamectin benzoate, 1-20% of dinotefuran, 5-15% of tea saponin and the balance of water. When the spray is prepared, water and tea saponin are added to a mixing kettle to be mixed uniformly, then emamectin benzoate and dinotefuran are added and are fully dispersed in water and tea saponin mixed liquor, then a sand mill is used for milling, a sample is taken to be detected, and the product is filled and packaged after the sample is qualified. The spray has the advantages that with water and natural tea saponin as carriers, the spray is safe to human and livestock, does not easily cause damages to crops and is safe and environment-friendly; the formula is simple; with water as the carrier, the spray is low in cost and has high cost performance; the water consumption for diluting agents is low, so that the spray is especially suitable to be used in arid areas and water-deficient high mountain areas; the spray can be used for low-volume and ultralow-volume spraying and has higher work efficiency than normal-volume sprays, thus saving the labor cost; the liquid drip loss is low and the pesticide utilization rate is high, thus reducing environmental pollution.

Description

technical field [0001] The invention relates to pesticides, in particular to a low-capacity spray containing emamectin benzoate and dinotefuran. Background technique [0002] The spraying method is the most common application method for the drug control of crop diseases and insect pests and sanitary pests, that is, a certain amount of pesticide and an appropriate amount of water or oil are used to prepare a liquid medicine, and the liquid medicine is sprayed into mist droplets with a spraying device. According to the amount of liquid sprayed per mu, the spraying method is often divided into constant spraying, low-volume spraying and ultra-low-volume spraying. [0003] 1. Constant spraying, pesticides are diluted with water, the dilution ratio is greater than 1000 times, and the spraying volume per mu is 45-60L, which is the conventional spraying method in the field of plant protection in my country at this stage. This spraying method has a large amount of spraying, low work...
