Fall high temperature, rainfall is frequent, field humidity is big, especially beneficial to all kinds of the growth of weeds,

 which not only and crops for water fight fat, also can cause a variety of malignant weeds,using chemical herbicide to

 weeding with high efficiency,good effect, low cost, the effective length and other advantages, but some malignant weed

 resistance particularly strong, ordinary herbicide is hard to kill it.Today I'm going to introduce you to a very good herbicide, 

which kills almostall broadleaf weeds, kills weeds thoroughly, has a long lasting effect, is cheap, and is easy for farmers

to accept. This herbicide variety is 2, 4-D.

what is 2,4-D ?

2,4-D is the abbreviation of 2, 4-dichlorophenoxyacetic acid. It is an auxin plant growth regulator discovered in the 1940s,

 which can promote the rapid  division of plant cells. It is often used to preserve flowers and fruits and promote fruit 

enlargement at a very low concentration of 10 mg/L.Under the high concentration of 500 mg/l, can accelerate the cell 

rapid division, can destroy the dicotyledonous plant transduction tissue, so that the growth and development are disturbed,

 the stem and leaves are twisted, the base of the stem bulges and coarser or cracking.It causes plants to die and is used 

as a herbicide.2, 4-D is a phenoxyacetic acid adsorbent herbicide, especially for dicotyledonous plants.

Range of application

2 methyl 4 chloride is a hormone herbicide, widely used in wheat field, corn field, paddy field, urban lawn, hemp crops and

other grasses.Mixed-use with other herbicide varieties, can also be used for road, railway, airport, oil depot, waste mountains,

forests and other non-cultivated land weeding, as well as apple, pear, orange, peach and other deep root fruit tree weeding,

can also be used for tea garden, rubber garden and other land weeding.

Control object

It is mainly used for the control of annual or perennial broad-leaved weeds and some sedges, such as wheat field soweringniangniang,

shepherd's purse, wheat bottle grass, wang not leaving line, tianhua, quinoa and other broad-leaved weeds;Used for corn and sorghum

fields to control back branching amaranth, xanthium, aconite, corydalis, etc.It is used in rice field for control of Herba trifoliate, Herba

alisma, Alisma alisma, Alismataceae, etc.

method of application

(1) Non-cultivated land use:Is used with glyphosate and can be used for highway, railway, airport, oil depot, forest fire prevention, such as

non-cultivated land behind the house weeding weeds in the exuberant growth period, the available 2 armor · glyphosate 47% water 200-300 - ml/mu,

evenly spray water 30 ~ 50 kg, will be the annual and perennial broadleaf weeds and grass of the field weeds by the roots.

(2) fields of use: with double fluoride sulfonic grass amine ketone and benzene cycling, grass and other herbicides mixture, can be in 2 ~ 4

weed leaf stage, with 40% 2, a double, fluorine can be dispersed by suspending agent 38-56 ml/mu, 30 kg evenly spray the water, which can

effectively kill the field niang artemisia, shepherd's purse, wheat grass, cowherb seed, Tian Xuan flower, quinoa broadleaf weeds.

(3) Corn field use:Can be mixed with nicotinsulfuron, atrazine and other herbicides, in maize 3-5 leaf stage, weed 2-4 leaf stage, can be used

64%2 methyl nicotinsulfuron atrazine dispersing granule 70-100 g/mu, mixed with water 30 kg uniform spray,Can effectively kill barnyard grass,

madang, cow sinew grass, amaranth, quinoa, purslane, iron amaranth, duck plantarus grass, endive, sweet aconite, specious sedvia and other

annual weeds and perennial weeds sedges weeds.
