Abstract
The invention belongs to the field of agricultural herbicide, and in particular relates to a compound herbicide. The compound herbicide contains diflufenican and oxyfluorfen which serve as active ingredients and a weight ratio of the diflufenican and oxyfluorfen is (10:1)-(1:10). The compound herbicide has the advantages that: 1, the synergistic effect is obvious, and the pesticide effect is greatly improved; 2, the pesticide effect is improved, the field consumption of the active ingredients is reduced, the production and use costs are reduced, and pesticide residue and environmental pollution are reduced; and 3, the compound herbicide consists of the active ingredients with different action mechanisms, the action sites are increased, pesticide resistance of weeds are overcome and delayed, and the compound herbicide is an important means for comprehensively preventing and controlling field weeds.
Description
Technical field
The invention belongs to the agricultural herbicide field, particularly a kind of complex weedicide.
Background technology
Diflufenican belongs to the carotenoid biosynthesis inhibitor, is the selectivity cornfield herbicidal of wide spectrum, causes chlorophyll to destroy 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.Behind the pharmacy application, at the medicine soil layer of the anti-leaching of soil table formation one deck, and at crop whole growth phase maintenance bamboo alive, when weed germination passed through this medicine soil layer, contact is the absorption medicament also, and the weeds root system also can absorb as if touching the medicine soil layer.Can the medicament effect be brought into play and depend on that can medicament cover the face of land equably.At the soil table or after the very near weed seed of soil table germinates, absorb medicament through young shoot and two approach of root system.When medicament upwards transmits, make young shoot decolouring or albefaction, last whole plant is wilted dead.The biosynthesis of medicament severe inhibition carotenoid and make plant produce the decolouring phenomenon, and destroy photosynthesis indirectly.Operating speed is directly relevant with light intensity.The photosynthesis of old plant tissue meeting Yin Xinye is suppressed and final influenced death.Can before the weeds bud or behind the bud, use.On the contrary, to some genus of Umbelliferae (carrot) and composite family, nearly unavailable.In a word, can prevent and kill off most annual broadleaf weeds, also effective to the grass family nutgrass flatsedge.As using with, can enlarge and kill the grass spectrum with other suitable gramineous herbicides.
Oxyfluorfen is before the selectivity bud or post-emergence herbicide.Before being used for cotton, round onions, peanut, soybean, beet, fruit tree and vegetables field bud, use behind the bud and prevent and kill off barnyard grass grass, sesbania, downy brome, green foxtail, datura, quackgrass, artemisiifolia, thorn chrysanthemum sth. made by twisting, piemarker, charlock unifacial leaf and broad leaved weed.Its very anti-leaching.Can be made into missible oil uses.Can prevent and kill off the unifacial leaf and the broad leaved weed of transplanting rice, soybean, corn, cotton, peanut, sugarcane, vineyard, orchard, vegetables field and forest nursery.The dryland rice dispenser can be used with butachlor; In dispensers such as soybean, peanut, cotton fields, can use with alachlor, trefanocide etc.; Locate dispenser in the orchard etc., can use with paraquat, glyphosate.
Often there is defective in various degree in the weed killer herbicide kind that contains the single-activity component in agriculture weeds in field control, be easy to generate pesticide resistance like weeds after the continuous administration, and the grass spectrum is narrow extremely, and application times is understood the weighting ring environment pollution more.Go up the weeds that produce resistance for control agricultural, a kind of way is to release the new component that new and existing kind do not have cross resistance.But the development cost of new active ingredient is high, and the construction cycle is long, and does not all catch up with the speed that weeds produce resistance forever.Other way is rotated etc. such as crop allocation adjustment, different agricultural chemicals, in the process of practical operation, is difficult to really play obvious effects.
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 that kills the grass spectrum, reduces active ingredient, practices thrift drug cost, reduces environmental pollution, is the important means of integrated control weeds in field.
The warp retrieval is not found Diflufenican at present and Oxyfluorfen is composite and the document of application.
Summary of the invention
The present invention aims to provide that a kind of resistance risk is little, cost is low, good drug efficacy, the lasting period is long, environmental pollution is little complex weedicide, and its active ingredient is Diflufenican and Oxyfluorfen.
