Problems solved by technology

[0004] At present, garden herbicides are limited by safety and herbicidal spectrum is also limited. Using a single herbicide alone cannot completely and effectively control the occurrence of garden weeds. Moreover, some herbicides are too water-soluble or have too long duration in the field. Long-term use, excessive dosage or uneven application are likely to cause residual toxicity

Abstract

The invention relates to a compound herbicide used for a garden. The compound herbicide is prepared from, by weight, 100-200 parts of oxyfluorfen, 100-200 parts of glyphosate, 80-180 parts of garden herbicide A, 50-100 parts of bentazone, 15-85 parts of triethanolamine, 14-64 parts of potassium dodecyl sulphate, 39-109 parts of paraquat, 6-46 parts of adjuvant, 5-40 parts of karaya gum, 5-40 parts of white carbon black, 15-65 parts of calcium acetate, 27-77 parts of complex enzyme, 20-80 parts of anhydrous potassium carbonate, 8-38 parts of catalyst, 55-125 parts of diflufenican and 60-140 parts of deionized water. The invention further discloses a preparation method of the compound herbicide. By compounding of the various herbicides, the weed control spectrum of the compound herbicide is expanded, the weed control effect is improved, the compound herbicide has the advantages of taking effect quickly, being long in lasting period, delaying the herbicide resistance, being thorough in weeding, low in residue content, low in toxicity, safe and environmentally friendly and the like, and the preparation is simple and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of pesticides, relates to herbicides, in particular to a compound herbicide used in gardens and a preparation method thereof. Background technique [0002] Herbicides are agents that can completely or selectively kill weeds. Since chemical herbicides began to be used in the 1940s, chemical herbicides have become an important means of weeding farmland to reduce labor intensity and improve work efficiency. At present, chemical herbicides occupy most of the market, but with the continuous application of chemical herbicides , has clearly exposed its disadvantages. First, the herbicide droplet drift, the volatilization of the liquid, the selectivity is not ideal, and the harm of the degradation product causes the phytotoxicity of the crops; secondly, the repeated use of the herbicide causes the population of drug-resistant weeds to increase. , The emergence of herbicide-resistant weeds and the increasingly serio...
