Embodiment 1

[0025] A broad-spectrum herbicide, in terms of active ingredients, the weight of the pesticide is composed of: 20% methenzazone, 40% promethazine, 8% ethylene glycol butyl ether, 5% surfactant, and the balance is water.

Embodiment 2

[0027] A kind of broad-spectrum herbicide, in terms of active ingredients, the weight of the pesticide is composed of: 25% fenmetrione, 30% promethazine, 6% ethylene glycol butyl ether, 7% surfactant, and the balance is water.

Embodiment 3

[0029] A broad-spectrum herbicide, in terms of active ingredients, the weight of the pesticide is composed of: 30% fenmetrione, 20% promethazine, 5% ethylene glycol butyl ether, 8% surfactant, and the balance is water.

[0030] The preparation method is as follows: after mixing the above-mentioned raw materials, carry out ultrasonic stirring to make them fully emulsified.

Abstract

The invention discloses a broad-spectrum herbicide. The broad-spectrum herbicide is prepared from the effective ingredients in percentage by weight: 20-30% of metamitron, 20-40% of prometryn, 5-8% of butyl glycol ether, 5-8% of surfactant and the balance of water. The broad-spectrum herbicide is prepared through combining two effective active ingredients in a special proportioning ratio and being matched with related auxiliaries. The broad-spectrum herbicide has the advantages that no precipitation exists during long-time storage, the dosage is low, the efficiency is high, and the drug effect duration is long. The broad-spectrum herbicide has the best prevention effect on just-germination weed, is broad in weed control spectrum and can be used for preventing and weeding gramineae weed and broad-leaf weed.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a broad-spectrum herbicide. Background technique [0002] Pesticides are used to kill insects, fungi, and other organisms that harm crop growth. The earliest pesticides used were DDT, BCH, etc., which can eliminate pests in large numbers. However, they have good stability, can exist in the environment for a long time, and accumulate continuously in animals, plants and humans, so they are eliminated. Later, organophosphorus pesticides, such as dichlorvos, were used instead of the original pesticides. However, their toxicity is too high and they are very harmful to humans and animals. In recent years, a group of high-efficiency and low-toxicity pesticides have appeared, and now people have found specific pesticides, namely hormone pesticides. [0003] my country's pesticide market is developing rapidly, and the industry as a whole is showing a good development trend. It has become the...
