Abstract

The invention provides a corn field herbicide synergistic additive and a preparation method and an application thereof. The corn field herbicide synergistic additive comprises the following raw materials: 30-70% of a penetrating agent wet-750, 5-10% of a wetting agent LAE-9, 1-5% of a complexing agent EDTA-ammonium salt, 5-20% of a dispersing and anti-drift agent M550, and 0.1-0.5% of a smell covering agent osmanthus fragrance, with the balance being deionized water. The wet-750, LAE-9, EDTA-ammonium salt and M550 are weighed according to the weight percentage and added into the deionized water for mixing to even and transparent, and the osmanthus fragrance is finally added for mixing to even and transparent, which is the product. The synergistic additive of the invention can greatly improve the wetting, spreading, adhering and penetrating properties of corn field post-seedling herbicide liquid, improve weed control effect in a corn field, reduce the amount of the herbicide, and is environmentally friendly.

Description

technical field [0001] The invention relates to the field of pesticide adjuvants, in particular to a cornfield herbicide synergist and its preparation method and application. Background technique [0002] Corn is an important food crop, feed crop and economic crop, and occupies an important position in my country's agricultural production and national economy. In order to meet the growing needs of animal husbandry, corn industry, rations and exports. my country's corn production is extremely rapid. Over the past 30 years, the planting area of ​​several major crops in my country has accounted for the total area of ​​food crops. It can be seen that the proportion of rice has increased by 13.4%, wheat has increased by 10.3%, and soybeans have decreased by 43.1%. Corn increased by 43.8%. Corn accounted for 25% of the total grain output. [0003] However, weed damage in cornfield is an important factor affecting corn yield. Weeds have well-developed root systems and compete wi...
