dipropyl-carbamothioicacis-propylester - Uses and synthesis methods
mechanism of action
Grass-killing and fierce soil treatment, during the germination and excavation of weed seeds, the chemicals are absorbed through the buds and roots, and conducted in the plant body, inhibiting and destroying the synthesis of ribonucleic acid and protein in sensitive plant cells, resulting in weeds The growth of some tissues in the leaves is inhibited. Most of the damaged weeds are destroyed and died at the growth point of the bud stage before the excavation. Although a few lightly damaged weeds can be unearthed, however, the young leaves are curled and deformed, and the stems are enlarged and cannot grow normally.
Preparation
A method for preparing a microcapsule of Quicaomeng, comprising the following steps:(1) Carrier preparation: polymerize according to the molar ratio of succinic acid: butanediol: lactic acid = 1:1:0.2-0.3 to obtain a carrier PBS-co-PLA;(2) Oil phase preparation: according to the mass ratio PBS-co-PLA: Quicaomeng: dichloromethane = 3.5-4.5:1:10 Weigh each component, dissolve the PBS-co-PLA, after it is completely dissolved, add the original medicine to dissolve the oil phase;(3) Water phase preparation: take deionized water according to the mass ratio of oil phase: water phase = 1:5-7, add emulsifier and dispersant, Dissolve the water phase;(4) Microcapsule preparation: Add the oil phase to the water phase to obtain an oil-water mixed emulsion, add a defoamer, solidify to form a microcapsule suspension, wash off. The method is simple in process and environmentally friendly. The obtained Mikaomeng microcapsule has a good shape, an encapsulation rate of 78%, a drug loading rate of 50%, an effective release period of 30 days, and a drug release rate of 94%. It is an ideal pesticide sustained-release agent.
Toxicity
acute oral LD50 in rats is 1500mg/kg, and acute percutaneous LD50 in rabbits is> 5000mg/kg. Acute percutaneous LD504640mg/kg in mice. The three-generation chronic feeding test of mice had no effect dose of 100mg/kg per day. No teratogenic, carcinogenic and mutagenic effects on animals within the test dose. There was no abnormality in the three-generation reproduction test and the delayed neurotoxicity test. The LC50 of rainbow trout is 13mg/L (24h), 11mg/L(48h), and the LC50 of sunfish is 10mg/L (24h). Quail oral LC501200mg/kg. At normal doses, it is safe for bees and natural enemies.
use
Selective soil treatment agent. During the process of weed germination and excavation, the agent is absorbed through the young buds and roots, and is conducted in the plant body to inhibit and destroy the RNA and protein synthesis of sensitive plant cells. Suitable for soybean, peanut, potato, sugar cane and tobacco fields to control wild oats, barnyard grass, crabgrass, Setaria, Cyperus, Herba, Herba and other gramineous weeds, as well as some broadleaf weeds such as hairy, purslane, quinoa, field convolvulus and Abutilon. Soybean and peanut fields are sprayed with 88.5% emulsifiable concentrate 22.5~30mL/100 m2, and then mixed with soil. The depth of mixed soil is 10 ~ 15cm, and the depth is not more than 5cm after sowing. Sugarcane field with 88.5% emulsifiable concentrate 30~37.5mL/100 m2, water spray sugarcane shallow planting field, can be applied before planting. Field with sugarcane planting depth> 15cm can be applied after planting. Due to the strong volatility of the agent, the soil should be mixed immediately after application.
production method
Preparation method I
The reaction of N,N-dipropylcarbamoyl chloride with sodium propyl mercaptan is made to kill the grass.
Preparation method II
N,N-dipropylaminothiocarboxylic acid is prepared by the interaction of dipropylamine and COS, and then combined with dipropyl sulfate to synthesize grass-killing.
