Description

The missible oil and the production method thereof that contain Diflufenican and clomazone
Technical field
The invention belongs to the agricultural herbicide field, particularly contain missible oil and the production method thereof of Diflufenican and clomazone.
Background technology
Diflufenican belongs to the carotenoid biosynthesis inhibitor, is the selectivity cornfield herbicidal of wide spectrum, causes Destruction of Chlorophyll and cell rupture, and plant is dead.To impose on autumn sowing Wheat and barley field before 125~250g/ha bud or behind the bud, prevent and kill off grass family and broad leaved weed, especially clearvers, Veronica and violet weeds.This medicament has following characteristics: broad weed-killing spectrum; But keeping from ill weeds; The drug effect phase is long in the soil; Efficacy stability; Can be mixed with other weed killer herbicides, enlarge the herbicide spectrum.
Clomazone has another name called clomazone, is the selectivity herbicide before seedling stage, and mainly root, the young shoot by plant absorbs, and upwards transporting diffuses to leaf section through xylem, suppresses the chlorophyll of sensitive plant and synthesizing of carotin.Form white seedling, dead in a short time.Lasting period is long, and the biologically active of clomazone in soil is sustainable more than 6 months, can be under recommended dose, and selectivity arranges succession crop, avoids poisoning.Applicable to crops such as soybean, sugarcane, potato, peanut, tobacco, paddy rice, rapes.Mainly prevent and kill off annual gramineae and the broad leaved weeds such as barnyard grass, green foxtail, lady's-grass, setaria glauca, eleusine indica, black nightshade, elscholtiza, water sour jujube pin, kitchen garden, piemarker, flowerofanhour root or herb, lamb's-quarters, little lamb's-quarters, penny cress, willow leaf thorn knotweed, pale persicaria, dayflower, Mao pig Xian, wolf tail grass, beggar-ticks, Siberian cocklebur, artemisiifolia.Perennial field thistle, setose thistle, corn sow thistle, meadow pine etc. there is stronger inhibitory action.
The different cultivars composition carries out composite, is the modal method of control resistant weed.Heterogeneity is carried out composite, can improve preventive effect, enlarges the consumption of herbicide spectrum, minimizing active ingredient, saves drug cost, reduces environmental pollution, is the important means of integrated control weeds in field.
Through retrieval, at present do not find Diflufenican with clomazone is composite and the document of application.
