Problems solved by technology

Hexazinone has the advantages of strong killing, long-lasting effect, and good leaching. The disadvantage is that the drug effect process is slow, 1 month for weeds, 2 months for shrubs, and 3-10 months for trees, but it is still enough to effectively control weeds. grass growth and reproduction
[0004] Due to the damage of weeds in the corn field, the yield is reduced. It is necessary to apply a large amount of herbicides for weed control every year to recover the loss of crop yield. Due to the abuse of herbicides,

Embodiment 1

[0046] Example 1 80% terbuthazine·hexazinone water dispersible granules

[0047] 68% terbuthylazine, 12% hexazinone, 2.5% dispersant maleic acid-acrylic acid copolymer, 2% sodium naphthalene sulfonate, 0.5% wetting agent sodium alkyl succinate sulfonate, a-olefin Sodium sulfonate 0.5%, fatty amide N-methyl taurine sodium salt 0.5%, disintegrant ammonium sulfate 3%, sodium chloride 3%, inert filler talcum powder make up 100%, after the mixture is fully mixed, carry out super Micro-airflow pulverization to obtain 750 mesh fine powder, then knead the obtained fine powder with an appropriate amount of water in a kneader, granulate through an extrusion granulator, and dry at 50°C in a fluidized fluidized bed to obtain 80% Terbuzine Hexazinone Water Dispersible Granules.

Embodiment 2

[0048] Example 2 40% terbuthine·hexazinone water dispersible granules

[0049] 34% terbuthylazine, 6% hexazinone, 2.5% dispersant maleic acid-acrylic acid copolymer, 2% sodium naphthalene sulfonate, 0.5% wetting agent sodium alkyl succinate sulfonate, a-olefin Sodium sulfonate 0.5%, fatty amide N-methyl taurine sodium salt 0.5%, disintegrant ammonium sulfate 3%, sodium chloride 3%, inert filler talcum powder make up 100%, after the mixture is fully mixed, carry out super Micro-airflow pulverization to obtain 750 mesh fine powder, then knead the obtained fine powder with an appropriate amount of water in a kneader, granulate through an extrusion granulator, and dry at 50°C in a fluidized fluidized bed to obtain 40% Terbuzine Hexazinone Water Dispersible Granules.

Embodiment 3

[0050] Example 3 80% terbuthazine·hexazinone water dispersible granules

[0051] 68% terbutyzine, 12% hexazinone, 3% polycarboxylate sodium salt as a dispersant, 1% calcium lignosulfonate, 0.5% wetting agent a-sulfo fatty acid methyl ester, 0.5% a-olefin sulfonate sodium %, fatty amide N-methyl taurine sodium salt 1.0%, disintegrant urea 1.5%, sodium sulfate 1.5%, kaolin supplement 100%. After the mixture is fully mixed and uniform, carry out ultrafine airflow pulverization to obtain a 750-mesh fine powder, and then add an appropriate amount of water to the kneader to knead the resulting fine powder, and then granulate it through an extrusion granulator. Dry at ℃ to get 80% terbuthazine hexazinone water dispersible granules.

Abstract

The invention discloses a weeding composition containing terbuthylazine and hexazinone and application of the weeding composition. The composition takes terbuthylazine and hexazinone as active components, and the mass ratio of terbuthylazine to hexazinone is (1-90): (1-90). The weeding composition disclosed by the invention has an obvious synergism effect and is suitable for removing various weeds in a corn field. By the use of the terbuthylazine and hexazinone composition, the medicinal effect and the prevention and treatment effect are mainly achieved. According to the composition, the medicine using amount is obviously reduced, the prevention and treatment range is expanded, and the economical cost is lowered; meanwhile, the residue amounts of medicines in agricultural products and the environment can be also reduced, and the drug resistance of weeds is delayed; the service life of the weeding composition is prolonged; the weeding composition has important economical, environment-protecting and ecological significances.

Description

technical field [0001] The invention relates to a pesticide herbicide composition and its preparation method and application, in particular to a herbicidal composition containing terbuthylazine and hexazinone, its preparation method and application. The herbicide composition has good effects in controlling various weeds in cornfields. Background technique [0002] Terbutylazine, English name: Terbutylazine, is a systemic herbicide, mainly absorbed through the roots, inhibiting the photosynthesis of plants, suitable for controlling various weeds in fields such as corn, vineyards and citrus, such as perennial ryegrass, Ryegrass and chickweed, chamomile, poppy, ryegrass, crabgrass, foxtail, etc. that germinate in autumn. Terbutyzine has a good quick-acting effect on weeds, with a lasting effect period of 3-10 weeks, and has a good effect on most annual dicotyledonous weeds, but the control effect on monocotyledonous weeds is not ideal. [0003] Hexazinone, English name: Hexaz...
