Clothianidin is used to control annual or perennial broad-leaved weeds and to control broad-leaved weeds such as spinach and endive in rape fields.


Clothianidin is a synthetic plant growth hormone. Its chemical structure is similar to many natural plant growth hormones, but it has better durability in the tissues of plants. It is mainly absorbed through the roots and leaves of the plant and then conducted in the plant body, so its conductivity is strong. After the weed is applied, it is absorbed by the leaves or roots of the plant, moves up and down in the plant body and is quickly transmitted to the entire plant. Low concentration of clopidic acid can stimulate the synthesis of plant DNA, RNA and protein, which leads to uncontrolled and disordered growth of cell division, and finally leads to destruction of tube bundles; high concentration of Clothianidin can inhibit cell division and growth.

It is used to control annual or perennial broad-leaved weeds in corn and sugar beet fields. After being applied to weeds, it is absorbed by the leaves or roots of the plant, and then conducted in the plant body, causing uncontrolled cell division and disordered growth, and finally resulting in vascular bundles. Destruction can also inhibit cell division and growth and is used to control 1-year or perennial broad-leaved weeds. At present, Clothianidin liquid and granules are mainly used to control broad-leaved weeds such as spinach and endive in rape field, and the effect is obvious.

1. Control of spring rapeseed and endives in spring rapeseed fields: perennial weeds such as spinach and endives are seriously harmful, with strong root reproductive ability, deep roots, and strong drug resistance. It is difficult to control, especially for agricultural production. Spring rapeseed production caused serious harm. 30% Clothianidin AS has the same control effect on Echinopsis and endive, with excellent control effect. In fields where the density of Echinops and endives is not high, the dosage of 30% Clothianidin can be reduced to 450ml/hm2. Fields with concentrated density and high density of Echinops and endives can be selectively sprayed without Need to use medicine in the whole field to save costs.

2. The effect of controlling broad-leaved weeds in summer corn fields: Based on the results of the two-year test, 75% Clothianidin soluble powder has a good imitating effect on summer corn asteraceae weeds spinach, spicy grass, needle needle grass, small sempervirium, artemisia argyi , Imitated better than the control agent 72% 2,4-D butyl ester emulsified oil treatment; it is generally good to imitated to Xiaxiazhu, Tongquan grass, mother grass, Mo Shangcai, etc.; to weeds of Chenopodiaceae and Amaranthaceae (Amaranthaceae) , Amaranth, etc.) have to follow suit. The recommended dose in the field is 225~315g/hm2, spraying at the 3-5 leaf stage of corn and the 3-5 leaf stage of weeds.
