Methyl benzene-purpose

Bensulfuron methyl is a selective internal inhalation and conduction herbicide for paddy field. It is also known as "Agricultural harvest time", "rice without straw" and "convenient farming". It is low toxic to human and livestock, and low toxic to fish, birds and bees. Previously used in rice fields to control sedge and broad-leaved weeds, it has been used to control broad-leaved weeds in wheat fields.

The fungicide can diffuse rapidly in water and be absorbed by weed roots and leaves and transferred to various parts, which hinders the biosynthesis of branched-chain amino acids. It is used to control annual and perennial broad-leaved weeds and Cyperaceae weeds in paddy fields, but has poor effect on gramineous weeds. It has good safety for wheat, rice and other crops. When used in wheat fields, the soil must be moist, the soil is dry and the efficacy is low.

It can effectively control * broadleaf weed, such as calamus, Lophophorus, damask, swording, shepherd's purse, big vetch, Chenopodium album, rice straw vegetable, etc., usually in the 2-3 leaf stage of the weeds, and when the soil is wet, the water is sprayed with 30-40 10% grams of sodium bicarubicon per mu. Rapid diffusion in water, temperature and soil have little effect on herbicidal effect and little mobility in soil.

Butachlor-purpose

Butachlor is a selective pre-bud herbicide of amide type, also known as norchlor, Marshall and Metrochlor. The pure product is light yellow oily liquid with slight aroma. It is insoluble in water and soluble in many organic solvents. The chemical properties are stable under normal temperature and neutral and weak alkaline conditions.

Under strong acid conditions, it will accelerate its decomposition and be degraded in the soil. It has low toxicity to human and livestock, stimulates skin and eyes, and is highly toxic to fish. It is mainly absorbed by weeds buds, followed by root absorption. When plants absorb butachlor, they inhibit and destroy protease in vivo, affect the formation of protein, inhibit the normal growth and development of weed buds and roots, so that weeds die. Effective for weeds before sprouting and 2-leaf stage, suitable for controlling barnyard grass in paddy field, annual grass weeds such as Cyperus heterotypus, Cordyceps militaris, Rhizoma Euphorbiae, Herba Aconiti, etc.

It can also be used to control hard weeds in winter barley and wheat, as well as weeds such as maidenhair, duck tongue grass, knotweed, pointed petal flower, flutter, clubhead grass, etc. but it has no obvious control effect on perennial weeds such as water trigonum, slant-stalk grub and wild sagittaria. When used in clay loam soil and soil with high organic matter content, the pesticide can be absorbed by soil colloid and can not be easily leached, and its validity can reach 1-2 months.
