Herbicides, Agrochemicals & Pesticides, have largely replaced mechanical methods of weed control in countries where intensive and highly mechanized agriculture is practiced. Herbicides provide a more effective and economical means of weed control than cultivation, hoeing, and hand pulling. Together with fertilizers, other pesticides, and improved plant varieties, they have made an important contibution to the increased yields we now have and serve to combat rising costs and shortages of agricultural labor. Without the use of herbicides, it would have been impossible to mechanize fully the production of cotton, soybeans, sugar beets, all grains, potatoes, and corn. Herbicides are classed as selective when they are used to kill weeds without harming the crop and as nonselective when the purpose is to kill all vegetation. Both selective and nonselective materials can be applied to weed foliage or to soil containing weed seeds and seedlings, depending on the mode of action. The term true selectivity refers to the capacity of an herbicide, when applied at the proper dosage and time, to be active only against certain species of plants but not against others. But slectivity can also be achieved by placement, as when a nonselective herbicide is applied in such a way that it reaches the weeds.

Early chemical herbicides were inorganic compounds. Herbicides such as ashes, common salts, and bittern have been used in agriculture since ancient times.Other inorganic herbicides include ammonium sulfamate, carbon bisulfide, sodium chlorate, sulfuric acid solutions, and formulations containing borate.

Organic herbicides began to be produced in earnest with dinitrophenol compounds in 1932. in the 1940, 2,4-dichlorophenoxyacetic acid is a highly selective systemic herbicide when used in very small quantities. 2,4-D was quickly adopted to control broad-leaved weeds in corn, sorghum, small grains, and grass pastures, as well as in lawns and other ornamental turf. The phenoxyaliphatic acids and their derivatives, another major group of organic herbicides, succeeded because of their selectivity and ease of translocation. Other groups of organic herbicides include organic arsenicals, substituted amides and ureas, nitrogen heterocyclic acids, phenol derivatives, triazines, and sulfonylureas.

Flurochloridone
Our Flurochloridone 250 CS is identical to Racer 25% CS from Makhteshim.

Herbicides Thidiazuron
1) Character index: 95%, 98% 25%WP, 50%WP 2) Packing: 1kg, 25kg

Sugarcane Herbicide 
20% Dieryou wettable powder, is a highly efficient, low-toxic, broad spectrum and long-acting cane herbicide. The product can prevent the growth of dozens of weed species. 

Cinosulfuron Herbicide
Applications: 
1) Biochemistry: branched chain amino acid synthesis (acetolactate synthase or ALS) inhibitor. Acts by inhibiting biosynthesis of the essential amino acids valine and isoleucine, hence stopping cell division and plant growth 
2) Uses: applied post-emergence to control many weeds, including Alisma, Annaal Cyperus Eleocharis, Marsilea, Potmnogeton and Sagittarla spp., Monochoria vaginalis and Sphenoclea zeylanica in transplanted, directly seeded, wet-sown, water-sown, and dry-sown rice crops, at 20 - 80g/ha. Also used in tropical plantation crops. For full weed spectrum, may need to be combined with a grass herbicide in tank-mix or sequential treatment.
