Inhalation LC50 (4 h) for rats >2.3 mg/l air.

 

NOEL (90 d) for rats 200 mg/kg diet; (1 y) for dogs 100 mg/kg diet. No significant effects observed in a 2 y carcinogenicity study in mice and a 3-generation reproduction study in rats.

 

Other Acute i.p. LD50 for rats 4200 mg/kg. Non-mutagenic.
Toxicity class WHO (a.i.) U
Target crops Mainly used for cotton defoliants, can also be used for apple trees, vines, hibiscus defoliation and beans, soybeans, peanuts and other crop sbarnyard grass, dog teeth, crabgrass, foxtail, quackgrass, cleavers and other weeds.
Function Description Functioned as plant growth regulator having cytokinin activity.

 

Mainly used for cotton defoliants, can also be used for apple trees, vines, hibiscus defoliation and beans, soybeans, peanuts and other crop sbarnyard grass, dog teeth, crabgrass, foxtail, quackgrass, cleavers and other weeds.

 

Mode of action Plant growth regulator, absorbed by the leaves, which stimulates formation of an abscission layer between the plant stem and the leaf petioles, causing the dropping of entire green leaves. Used for defoliation of cotton, in order to facilitate harvesting; applied at 0.21 kg/ha per season.

 

Significantly inhibited, the amount of 0.3 ~ 3kg/hm2. If the amount of cotton 0.5kg/hm2, 50% to 60% boll opens medication 500L/hm2 of the preparation diluted aqueous solution sprayed on the plants, 98% defoliation effect.
Can also be used to control barnyard grass, dog teeth, crabgrass, foxtail, quackgrass, cleavers and other weeds, dosage 3kg/hm2, control efficiency of nearly 100%.
Storage Keep in Dry and cool place. Store under acidic conditions
Packing Details 25kgs/drum,1kg/bag or according to customers demand.
Thidiazuron (TDZ) Description:
Thidiazuron (TDZ) has gained a considerable attention during past decades due to its efficient role in plant cell and tissue culture. Wide array of physiological responses were observed in response to TDZ application in different plant species. TDZ has shown both auxin and cytokinin like effects, although, chemically, it is totally different from commonly used auxins and cytokinins. A number of biological (physiological and biochemical) events in cells are induced or enhanced by TDZ, but the mode of action of TDZ is yet unknown. However, varieties of underlying mechanisms were revealed by reports showing how morphogenic events were induced by application of TDZ. Other reports showed that TDZ may modify endogenous plant growth regulators, either directly or indirectly and produce reactions in cell/tissue, necessary for its division/regeneration. Other possibilities include modification in cell membrane, energy levels, nutrient absorption, transport and assimilation, etc.
Thidiazuron (TDZ) mainly used as defoliant on cotton; also, sprayed on grapes, apple, peach, mango etc.
