Toxicity
the acute oral LD50 of rats is 1675~2165 mg/kg(1800 mg/kg), and the acute percutaneous LD50 of rabbits is 2225~4050 mg/kg. Rats were fed for 2 years with no effect dose of 200mg/kg. It has mild irritation to rabbit eyes and moderate irritation to skin. Accumulation is moderate in animals. The Ames test was negative. Mutagenic Ames test (TA1535, TA98, TA100) has mild mutagenic effect reported abroad. High dose group (1/5 LD50) can increase micronucleus rate of mouse bone marrow cells. Under the experimental conditions, there was no teratogenic effect and no carcinogenic effect on rats and rabbits. The LC50 of rainbow trout is 1.2mg/L (96h), and the acute oral LD50 of quail is 2251mg/kg.
use
1. selective soil treatment agent has special effect on controlling wild oats. After the weed bud sheath or the first cotyledon absorbs the agent, it affects the protein synthesis and mitosis of the cell, inhibits the cell elongation, and causes the weed to die before it is unearthed. It can be used in barley and wheat fields to prevent weeds such as wild oats, and can also be used in crops such as rape, pea, flax, sugar beet, green pear and soybean. The dosage is 8~16g active ingredient/100 m2, which is mixed with soil.
2. this product is a selective soil treatment agent for controlling wild wheat, and is suitable for controlling wild oats in wheat, barley, highland barley, rape, pea, broad bean, flax, beet, soybean and other crop fields.
3, suitable for wheat, highland barley, rape, peas, flax, sugar beet, soybeans and other crops to control wild oats
production method
1. add diisopropylamine to sodium hydroxide solution, stir and cool, and introduce carbon disulfide at 0-5 ℃ until the calculated amount is completed. Add 1,1 ',2,3-tetrachloropropene into the reaction solution and react at 0-65 ℃ for 6h. Cooling rest delamination. The upper layer is mother liquor and the lower layer is crude product. The crude product is distilled under reduced pressure, and the reacted low-boiling substances such as tetrachloropropene are steamed out, and the remaining amber thick oil-like liquid is wild wheat. Raw material consumption quota: diisopropylamine (96%)300 kg/t, tetrachloropropene (80%)600 kg/t, chlorine 600 kg/t.
2. dissolve 3g of sodium hydroxide in 20mL of water, mix it with 5.5g (98%) diisopropylamine at room temperature, cool the reaction solution to 0~5 ℃, introduce oxygen sulfide carbon gas under stirring, absorb about 3g, precipitate a large amount of crystals, continue the heat preservation reaction, and put 18g (70%)1,1,2,3-tetrachloropropene into the reaction solution under stirring, continue the reaction at 0~65 ℃ for 6h, cool to room temperature, let stand and delaminate, distill the lower crude product under reduced pressure, and after the low boiling substance is distilled, the remaining amber viscous liquid is the product.
