crop application | the main component of green grass is trichloropiroacetic acid, which is mainly registered as a mixture with glyphosate in China, the dosage forms registered are all wettable powders, and the use scope is non-cultivated land to control broad-leaved weeds, small shrubs, etc. The composition is also registered in many European and American countries in rice, sugarcane and corn and other gramineous crops, and the domestic application in these crops is basically blank. |
toxicity | rat acute oral LD50 was 729mg/kg (male)630 (female) mg/kg, rabbit acute percutaneous LD50350mg/kg. It has mild irritation to rabbit eyes and no irritation to skin. The subacute oral no-effect dose in rats was 5.5mg/kg per day, and the chronic oral no-effect dose was 30mg/kg per day. In the experimental conditions, no teratogenic, carcinogenic, mutagenic effects of animals. |
uses | acts on nucleic acid metabolism, so that plants produce excess nucleic acid, so that some tissues are transformed into meristem, resulting in leaves, stem and root deformity, storage material depletion, vascular bundle tissue embolization or rupture, plant death. It is used for weed control and irrigation before afforestation, maintenance of fire line, and rehabilitation of pine tree and stand. Can be controlled in addition to lessii, Corydalis Wood, Mongolia, black birch, balsam, Poplar, Mountain Rose, Ulmus pumila, Artemisia, bupleurum, Platycodon grandiflorum, sanguisorba, clematis, nathana, sweet clover, Tang pine grass, pterygotes, acer, Willow, Sorbaria, mosquito grass, horse celery, Polygonatum odoratum, chrysanthemum, clove, hypericum, plum flower, Mountain Top, plum, pear, chrysanthemum. The tending dosage of young forest was 1kg/hm2, and the effective component of pre-afforestation and fire line was 1.95kg/hm2. Attention should be paid to the strict control of pine and spruce dose, more than 1kg/hm2 easy to produce damage. The product can be absorbed by the leaves and roots of plants and transferred to plants. It can be used to control weeds in rice fields and wheat, and can also be used in botanical gardens (such as oil palm and rubber). This product can be absorbed by the leaves and roots of plants and transferred to plants. 90g(a. I.)/ha is used in combination with 2,4-drops or Malon to control weeds in rice and wheat fields (not used in barley fields); It can also be used in plantations (such as oil palm and rubber), with 125 ~ G (a. I.)/ha can be controlled to cover plants, with 0.72~10kg(a. I.)/ha, which can control adenophorum and other major weeds; In the pasture, l ~ 2kg(a. I.)/ha can control annual and perennial herbaceous weeds; 2 ~ 4kg/ha can control Rubus and other woody weeds; In forest, 4 ~ 8kg/ha for fertility treatment; 1.5~2.0/ha for the treatment of conifers; 2 ~ 8kg/ha, for the industrial area of the herbicide, the herbicide dosage of 0.24 ~ 10kg/ha. |
