(1) technical field
The present invention relates to weed killer herbicide field, particularly a kind of herbicide composition for paddy fields containing Stam F-34, clomazone.
(2) background technology
Stam F-34, Acetochlor, the third careless amine, butachlor are all weed killer herbicides of amide-type high selectivity, and different is that Stam F-34 belongs to contact killing type weed killer herbicide, and Acetochlor, the third careless amine, butachlor belong to inner-adsorption conduction-type herbicide.Stam F-34 is mainly used in rice seedling bed or live field, is the specific drug of preventing and kill off barnyard grass, also can be used for preventing and kill off other multiple grass family and broadleaf weeds, as Monochoria vaginalis, Chinese celery, lady's-grass, green foxtail etc.; Stam F-34 is transporting hardly in plant corpus, just work in medicament contact site, its mechanism of action is many-sided, not only destroy the photosynthesis of plant, but also suppressing respiration and phosphorylation, RNA and protein are synthetic etc., thereby the physiological function of sensitive plant is affected, accelerate dehydration, blade dried-up gradually, finally dead.Resolve into rapidly innocuous substance because Stam F-34 is hydrolyzed enzyme in paddy rice body, paddy rice is to the degradation capability of Stam F-34 than barnyard grass large 20 times, so to rice safety.
Acetochlor mainly absorbs by the hypocotyl of monocotyledonous coleoptile or dicotyledon, absorbs backward upper conduction, and by impede protein matter is synthetic, Cell growth inhibition stops weeds young shoot, young root growth, and then dead; The energy force rate broad leaved weed that grassy weed absorbs Acetochlor is strong, is better than broad leaved weed so prevent and kill off the effect of grassy weed.About the lasting period 45 day of Acetochlor in soil, mainly by microbial degradation, the mobility in soil is little, mainly remains in 0 ~ 3 cm layer of soil.The butachlor mainly young shoot by weeds absorbs, and then conducts complete stool and works, before bud and all can use seedling stage.Plant absorbs after butachlor, suppresses in vivo and destroys protease, affects the formation of protein, suppresses weeds young shoot and young root normal growth and grows, thereby make weeds death; On clay loam and the higher soil of the content of organic matter, use, medicament can be absorbed by soil colloid, is difficult for being leached, and the special efficacy phase can reach 1 ~ 2 month.The third careless amine is that weed seed absorbs medicament in germination process, and root absorption is poor, can only make the front soil treatment of bud.Paddy rice germination period is also more responsive to the third careless amine, and for ensureing early stage drug safety, the third careless amine often adds safener to use together.The butachlor mainly young shoot by weeds absorbs, and then conducts complete stool and works, before bud and all can use seedling stage.Plant absorbs after butachlor, suppresses in vivo and destroys protease, affects the formation of protein, suppresses weeds young shoot and young root normal growth and grows, thereby make weeds death; On clay loam and the higher soil of the content of organic matter, use, medicament can be absorbed by soil colloid, is difficult for being leached, and the special efficacy phase can reach 1 ~ 2 month.
Clomazone is selectivity systemic herbicide, absorbs by root, the young shoot of plant, and upwards transporting, diffuses to leaf portion through xylem, suppresses the chlorophyll of sensitive plant and synthesizing of carotin.Form white seedling, dead in a short time.The biologically active of long ， clomazone of lasting period in soil is sustainable more than 6 months, can be under recommended dose, and selectivity arranges succession crop, avoids poisoning.
