Abstract

A novel herbicide for rice planting is made from, by weight, 8-14 parts of 4,5-dichloro-N-octyl-3(2H)-isothiazolone, 22-32 parts of butralin, 15-25 parts of 5-fluorosalicylic acid, 13-22 parts of sodium sulfate, 9-15 parts of propisochlor, 16-25 parts of lactofen, 10-19 parts of fomesafen, 9-16 parts of quizalofop-p-ethyl, and 210-300 parts of water. A preparation method comprises the main steps of adding the corresponding parts by weight of the materials in sequence, adjusting temperature, and mixing well. The novel herbicide and the preparation method thereof have the advantages that containing isothiazoline disinfecting ingredients, the herbicide is specific to rice weeding and functional to disinfect rice and has multiple functions, high practicality and wide range of application; thematerials for the herbicide are low in price and easy to obtain, the preparation method is simple, the cost is low, and the weeding effect is good.

Description

technical field [0001] The invention relates to the field of rice planting, in particular to a novel herbicide for rice planting and a preparation method thereof. Background technique [0002] Rice is an annual grass plant, about 1.2 meters high, with long and flat leaves, and panicles composed of many spikelets. The fruit is rice, which is called rice or rice after shelling. Rice can be divided into indica rice and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice. Paddy rice is called rice or rice after shelling the rice grains. In addition to being edible, rice can also be used as industrial raw materials for wine making and sugar refining. Rice husks and rice straws also have many uses. Rice belongs to the Poaceae Oryza genus and is an extremely ancient crop. According to archaeological findings, rice has been planted in my country for at least 7,000 years. There are two species of cultivated rice in the world, that is, Asian ...
