Glyphosate was originally used for controlling of grass weeds in rubber plantations and can allow the rubber tapping a year earlier and increase the production capacity of the old rubber tree. It is currently gradually extended to forestry, orchards, mulberry fields, tea plantations, rice and wheat, and rape rotation land. Different kinds of weeds have different sensitivity to glyphosate and therefore the dosage is also different. For example, for weeds such as barnyardgrass, green bristlegrass, Alopecurus aequalis, Eleusine indica, crabgrass, cleavers and other annual weeds, the dosage calculated according to the amount of the active ingredient should be 6~10.5 g/ 100 m2. For semen plantaginis, horseweed, and dayflower, the dosage of being an active ingredient should be 11.4~15g/100m2. For cogon, Panicum repens, and reeds, the dosage can be 18~30 g /100m2, generally the used amount of water should be 3~4.5 kg. Apply direct and even spray to the stems and leaves of the weed. It is a kind of non-selective, post-emergent herbicide with short residue life. It can be used for control of perennial deep roots weeds, annual and biennial weeds, sedges and broadleaf weeds. Glyphosate is an organic phosphorus herbicide and its herbicidal property was found by D. D. Baird (US) in 1971. Until to the 1980s, it has become an important species in the world herbicide. Herbicide Nonselective, postemergence, broad spectrum herbicide used to control annual and perennial grasses, sedges, broad-leaved and emerged aquatic weeds. This herbicide is also used to control insects on fruit trees.


2-Mercaptobenzothiazole is an intermediate of the herbicide benzothiazide, as well as a rubber accelerator and its intermediate. 2-Mercaptobenzothiazole is a general-purpose vulcanization accelerator widely used in various rubbers. It has a rapid promotion effect on natural rubber and synthetic rubber usually vulcanized with sulfur. However, the use of zinc oxide, fatty acid and other activation is required. Often used in combination with other accelerator systems, such as dithiothiuram and tellurium dithiocarbamate can be used as an accelerator for butyl rubber; used in combination with a tribasic lead maleate chemicalbook, can be used for light colors Water-resistant chlorosulfonated polyethylene compound. It is often used in combination with dithiocarbamate in latex, and can be vulcanized at room temperature when used with diethyldithiocarbamate diethylamine. The product is easy to disperse in rubber and does not pollute. However, due to its bitter taste, it is not suitable for food contact rubber products. Accelerator M is an intermediate of accelerators MZ, DM, NS, DIBS, CA, DZ, NOBS, MDB, etc. 2-mercaptobenzothiazole with 1-amino-4-nitroanthraquinone and potassium carbonate in dimethyl Reflux in formamide for 3h to prepare dye-dispersed brilliant red S-GL (CIDisperseRed121). This dye is used for dyeing polyester and its blended fabrics. When 2-mercaptobenzothiazole is used as an electroplating additive, it is also called acid copper plating brightener M, and it is used as a spreading brightener in bright copper plating with copper sulfate as the main salt. In addition, the product is also used to prepare pesticide fungicides, nitrogen fertilizer synergists, oil removal and lubrication additives, organic anti-ashing agents in photographic chemistry, metal corrosion inhibitors, etc. In addition, it is a reagent for chemical analysis. The product has low toxicity and has a stimulating effect on the skin and mucous membranes.


A phenyl urea herbicide. Pre-emergent herbicide. Diuron is a urea compound used as a preemergence herbicide in soils to control germinating broad-leaved grasses and weeds in crops such as apples, cotton, grapes, pears, pineapple and alfalfa; sugar cane ?owering depressant.

Bensulfuron methyl

Bensulfuron methyl is a selective systemic conductive herbicide in rice fields, also known as Nongdeshi, rice without grass, and farming. It has low toxicity to humans and animals and low toxicity to fish, birds and bees. Bensulfuron methyl was used to control sedge and broad-leaved weeds in rice fields, and has been used to control broad-leaved weeds in wheat fields. The medicament can be quickly diffused in the Water of Chemicalbook, absorbed by the weed roots and leaves and transferred to various parts, hindering the biosynthesis of branched-chain amino acids. It is used in rice fields to control annual and perennial broad-leaved weeds, sedge weeds, and has poor effects on gramineous weeds. It is safe for wheat, rice and other crops.

Tribenuron methyl

Methomyl is a broad spectrum carbamate insecticide with both contact and oral toxicity to control chewing and sucking Lepidotera, Homoptera, Coleoptera and Hemiptera pests in vegetable, orchard, vine and field crops.Herbicide: Used to control annual grasses and broadleaf weeds on barley, blueberries, oats, wheat, flax and rape seed (canola). Registered for use in EU countries . Registered for use in the U.S. U.S. Maximum Allowable Residue Levels for the residues of the herbicide tr
Herbicides are agents that can cause weeds to die completely or selectively, also known as herbicides, a class of substances used to eliminate or inhibit plant growth.
