Embodiment 1

[0044] Embodiment 1 is a dosage form preparation example, and Embodiment 2 is a biological embodiment.

[0045] Example 1:

[0046] a. Wettable powder:

[0047] 30 parts by weight of effective active composition and 3 parts by weight of sodium dodecylbenzenesulfonate used as wetting agent, 20 parts by weight of granular silica, 5 parts by weight of lignin used as dispersant Sodium sulfonate and 42 parts by weight of kaolin are pulverized in a jet mill.

[0048] b. Water dispersible granules:

[0049] 60 parts by weight of effective active composition and 2 parts by weight of sodium dodecylbenzenesulfonate used as wetting agent, 5 parts by weight of superfine white carbon black, 5 parts by weight of polycarboxylate used as dispersant It is obtained by pulverizing salt, 5 parts of sodium sulfate used as a disintegrating agent and 75 parts of kaolin in a jet mill, adding an appropriate amount of water for kneading, and then granulating and drying.

[0050] c. Suspoemulsion

Embodiment 2

[0055] Location: Jiangsu, Xinyi

[0056] Corn sowing time: May 20, 2016 Application period: in front of the temple after sowing Survey: 30 days after application

[0057]

[0058] Conclusion: The actual control effect of naquath mixed with acetochlor, alachlor, butachlor, metolachlor, promethachlor, and atrazine is higher than the expected theoretical control effect of their mixed use, and can expand The herbicidal spectrum proves that the mixed use of diquath with acetochlor, alachlor, butachlor, metolachlor, propachlor, and atrazine has a synergistic effect.

Abstract

The invention discloses a chlorthal-containing weedicide composite, and relates to the weedicide composite with improved performance, and a preparation method and application thereof. The chlorthal-containing weedicide composite is a mixture which is formed by a compound (A) and a specific compound (B), and can effectively control and kill annual grassy weeds and broadleaved weeds in a corn field. The control effect is remarkably higher than that achieved by singly using the compound (A) and the compound (B); the using amounts of a plurality of active ingredients are reduced.

Description

technical field [0001] The present invention relates to herbicidal compositions with improved properties, in particular to compositions containing napropen and the amide herbicides acetochlor, alachlor, butachlor, metolachlor, propachlor or triazine Herbicidal composition and application of atrazine-like herbicide. Background technique [0002] The common name of compound (A) is Diquat, abbreviated as DCPA, and its chemical name is 2,3,5,6-dimethyl tetrachloroterephthalate. It is a benzoic acid herbicide with systemic conductivity. It can be used for pre-emergence treatment, and can also be used for stem and leaf spray. It is suitable for crops such as corn, kidney beans, cucumbers, onions, peppers, strawberries, lettuces, eggplants, turnips, etc. It is also suitable for lawns and ornamental plants. It can prevent and control annual grass weeds and certain broad-leaved weeds, such as foxtails and horses. Tang, brocade, purslane, chickweed, dodder, etc. [0003] Acetochlor...
