Problems solved by technology

[0003] A large number of herbicide varieties have been developed for the needs of chemical weeding in farmland for production selection; however, each herbicide has a specific type of weed to be controlled, and now it is very lacking that it can selectively control all weeds in the whole growth period of crops. At the same time, long-term use of a single herbicide species can lead to weed resistance or cause changes in weed species and rapid replacement of weed populations, which greatly increases the difficulty of chemical weeding in farmland. At the same time as new herbicides, the mixed use of two or more herbicide varieties also came into being

Embodiment 1

[0016] Herbicide wettable powder: accurately weigh glufosinate-ammonium 25kg, cyprosulfuron-methyl 16kg, quinclorac 6kg, cyclohexanedione 12kg, methyl polytrimethicone 0.001kg, ferric ammonium citrate 0.001kg, 0.01kg of magnesium sulfate, 6kg of fenmetrazone, 13kg of octylphenol polyoxyethylene ether sulfonate, and 14kg of polyethylene glycol were mixed in a mixer, and then jet milled to obtain a wettable powder of herbicide.

Embodiment 2

[0018] Herbicide water dispersible granules: Accurately weigh glufosinate-ammonium 26kg, cyprosulfuron-methyl 21kg, quinclorac 6kg, cyclohexanedione 12kg, methyl polytrimethicone 0.002kg, iron citrate 0.003kg of ammonium, 0.02kg of magnesium sulfate, 5kg of fenflumezone, 23kg of octylphenol polyoxyethylene ether sulfonate, and 4kg of polyethylene glycol were mixed in a mixer, and an appropriate amount of water was added as a kneading agent to fully knead, and then squeezed The granulator is dried and sieved to obtain the herbicide water dispersion.

Embodiment 3

[0020] Herbicide suspension: accurately weigh glufosinate-ammonium 28kg, cyprosulfuron-methyl 23kg, quinclorac 6kg, cyclohexanedione 12kg, methyl polytrimethicone 0.001kg, ferric ammonium citrate 0.002 kg, 0.01 kg of magnesium sulfate, 6 kg of fenflumezone, 8 kg of octylphenol polyoxyethylene ether sulfonate, 9 kg of polyethylene glycol, supplemented with 1000 kg of water, added to a sand mill to grind, and obtained after filtration.

Abstract

The invention provides compound weedicide. The compound weedicide is characterized by being prepared from the following raw materials: glufosinate-ammonium, cyclosulfamuron, quinclorac, cyclohexanedione, topramezone, octylphenol polyoxyethylene ether sulfonate, methyl trimethicone, ferric ammonium citrate, magnesium sulfate and polyethylene glycol. The compound weedicide provided by the invention can be prepared into wettable powder, water dispersible granules, a suspending agent and microcapsule suspension. Compared with a single dosage, the compound weedicide has more remarkable performances and a higher product quick-acting effect; the compound weedicide not only can be used for preventing and removing weeds of common non-cultivated lands, orchards and farmlands, but also can be used for treating stems, leaves and soil of tolerant crop lands.

Description

technical field [0001] The invention relates to the field of pesticide production, in particular to a compound herbicide and a preparation method thereof. Background technique [0002] With the rapid development of science and technology, chemical weeding, as a modern and practical technology, plays a huge role in weed control; although the development time of chemical weeding technology is not long, but the development speed is relatively fast; with the modernization of China's agriculture With the development and gradual transfer of agricultural labor force, cultivation methods tend to be large-scale and intensive, and the demand for pesticides has increased significantly; among them, the growth rate of herbicides in recent years is much higher than the development level of insecticides and fungicides, accounting for about to 1 / 3 of the proportion of pesticide production; at present, there are many kinds of herbicides, which can be divided into stem and leaf treatment agen...
