[0003] In the past, the author or inventor used the compound agent of isoproturon as weeding in rice transplanting field and direct seeding field, such as the registered benzazuron. Yes, the registration and use of a single dose of isoproturon in rice fields has never been reported. Studies have shown that substituted urea herbicides can significantly inhibit the accumulation of substances in rice seedlings and the vitality of the root system

Embodiment Construction

[0021] Under the conditions of potting in the greenhouse, a comparative experiment was carried out, and the planting conditions of 7 groups of herbicides with different formula ratios were compared with those without herbicides. The wetting agent is fatty alcohol, the emulsifier is alkylnaphthalene sulfonate formaldehyde condensate sodium salt, the dispersant is methylnaphthalene sulfonate sodium formaldehyde condensate, and the protective agent is dimethylaminobenzenediazosulfonate sodium salt. The weight ratio is as follows , and the rest are filler kaolin.

[0022] The planting experiment was rice seedlings, and the weeds were mainly monocotyledonous barnyardgrass. The spraying time is the 2-3 leaf stage of japonica rice and barnyard grass, and the inspection starts after 25 days. The inspection results are shown in Table 1:

Abstract

The invention relates to a herbicide as well as a preparation method thereof, and particularly relates to herbicide isoproturon applied to a rice field as well as a preparation method of the herbicide isoproturon. The rice field herbicide isoproturon comprises isoproturon, auxiliaries and packing; the auxiliaries contain wetting agents, emulsifying agents, dispersion agents and protection agents. Because components with different effects, such as the wetting agents, the dispersion agents and the emulsifying agents, are added into the herbicide provided by the invention, and take effects with the protection agents, so that the protection agents can take effects effectively.

Description

technical field [0001] The invention relates to a herbicide and a manufacturing method thereof, in particular to a single-dose isoproturon herbicide used in paddy fields and a manufacturing method thereof. Background technique [0002] Isoproturon is a substitute urea herbicide, currently it is mainly used for the control of grass weeds and most broad-leaved weeds in wheat, corn, peanut, cotton and other dry lands. [0003] In the past, the author or inventor used the compound agent of isoproturon as weeding in rice transplanting field and direct seeding field, such as the registered benzazuron. Yes, the registration and use of a single dose of isoproturon in rice fields has never been reported. Studies have shown that substituted urea herbicides can significantly inhibit the accumulation of substances in rice seedlings and the vitality of the root system. In wheat and rice intercropping fields, after applying substituted urea herbicides in wheat fields, rice seedlings in s...
