Problems solved by technology

[0011] However, in view of the characteristics of malignant weeds in paddy fields such as barnyard grass, Cyperus cyperi, and Fructus chinensis, if the above-mentioned herbicides are used alone, there are still problems of narrow herbicidal spectrum and incomplete weeding. Not only the cost is high, but also cannot Achieve a one-time application to completely remove grasses such as barnyardgrass, broad-leaved weeds such as sagittarius, and Cyperaceae such as Cyperus cyperus

Abstract

The invention provides a paddy field herbicide composition with bentazon and bispyribac-sodium as active ingredients. The herbicide composition comprises 10wt%-92wt% of bentazon and bispyribac-sodium, 0-5wt% of agriculturally acceptable adhesive, 0-5wt% of stabilizer, 0-3wt% of cosolvent, 2-5wt% of synergistic agent, 5-10wt% of surface active agent and the balance of agriculturally acceptable carrier or mixture of water and alkaline, wherein the weight ratio of the bentazon and the bispyribac-sodium is 15:1 to 50:1. The composition can be prepared into particles, wettable powders or water solutions, is used for controlling and removing grassy, broad and sedgy weeds in the transplanted paddy fields or seedling transplanting fields, has the advantages of safe use, flexibility and convenience, and also can be flung, sprayed and atomized.

Description

technical field [0001] The invention relates to a pesticide combination preparation, in particular to a herbicide composition of bentazon and bispyribac for controlling weeds in paddy fields. technical background [0002] With the development of agricultural science and technology, the emergence and widespread use of chemical herbicides not only reduces the labor intensity of farmers, but also can control weeds more effectively and increase production. However, the extensive use of herbicides inevitably brings environmental problems. The toxic substances contained in it not only pollute the ecological environment, but also affect human health and endanger food safety. Therefore, in recent years, the research and application of herbicides are developing in the direction of high efficiency, low toxicity, and low residue green environmental protection. At present, the requirements for herbicide combinations are not only easy to use and thorough weed control, but also hope to ...
