Problems solved by technology

However, the development cost of new active ingredients is high, the development cycle is long, and it can never keep up with the speed of weed resistance
Other methods, such as crop layout adjustment, rotation of different pesticides, etc., are difficult to achieve obvious effects in actual operation.

Embodiment 1

[0030] A herbicidal composition containing dimethenamid and thifensulfuron-methyl, which is an emulsifiable concentrate, consists of the following components in weight percentage: dimethenamid, 58%; thifensulfuron-methyl, 7%; the emulsifier is selected For Nongru 500# and Nongru 601#, the dosage is 4% and 6% respectively; xylene, the balance.

[0031] Preparation method: add active ingredients dimethenamid and thifensulfuron-methyl herbicide into the carrier according to the formula ratio, and add surfactant and other functional auxiliaries therein, and stir and mix evenly in a stirring mixing tank. The stirring and mixing kettle can be enamel reaction kettle, stainless steel stirring kettle, etc.

Embodiment 2

[0033] A herbicidal composition containing dimethenamid and thifensulfuron-methyl, which is a suspoemulsion, consists of the following components in percentage by weight: dimethenamid, 40%; thifensulfuron-methyl, 20%; emulsifier Agricultural milk OP-10, 2%; dispersant polycarboxylate, 7%; thickener selection of xanthan gum, the dosage is 0.1% respectively; antifreeze agent ethylene glycol, 5%; defoamer silicone compounds, 0.5%; water, balance.

[0034] Preparation method: according to the proportion of the formula, first put the active ingredient thifensulfuron-methyl herbicide in the reaction kettle, add water and mix evenly, and make a thick suspension through the grinding process; then dimethenamid, surfactant and other functional The additives are added to the reactor, mixed evenly and passed through high-speed shearing to prepare the final suspoemulsion. The main equipment is batching kettle, colloid mill or homogeneous mixer, sand mill.

Abstract

The invention belongs to the field of herbicides, discloses a weeding composition containing dimethenamid and thifensulfuron methyl and aims to solve problems of proneness to causing resistance of injurious insects and low safety of existing single-component herbicides. Effective components of the weeding composition include dimethenamid and thifensulfuron methyl in a weight ratio of (35:1)-(1:25). By synergistic effects of the two effective components in the weeding component, herbicide consumption can be effectively reduced, herbicide cost is reduced, and environmental pollution is abated; drug resistance of weeds can be retarded, and long action time is realized; the weeding composition is safe to crops, human, animals and environment.

Description

technical field [0001] The invention relates to the field of herbicides, in particular to a herbicidal composition containing dimethenamid and thifensulfuron-methyl. Background technique [0002] Dimethenamid, a chloroacetamide compound, is mainly used in crops such as corn, soybean, peanut or sugar beet to control a variety of annual grass weeds such as barnyardgrass, crabgrass, beef tendon, etc. and broad-leaved weeds such as Amaranth, ghost needle grass, shepherd's purse, bermudagrass, sweet chamomile, etc., are safe to crops. [0003] Thifensulfuron methyl English common name Thifensulfuron methyl, molecular formula C12H13N5O6S2. Thifensulfuron-methyl is a high-efficiency selective post-emergence stem and leaf treatment agent, which is a systemic conduction post-emergence herbicide. Synthesized, prevents cell division and stops growth of sensitive crops. It can be used to control annual broad-leaved weeds in cereal crops. It is mainly absorbed and transmitted through...
