Abstract
The present invention relates to an aqueous suspending agent containing mesotrione and clopyralid, which is composed of the following components by weight: 1-70% of mesotrione; 1-70% of clopyralid; 1-30% of a surfactant; 0-40% of other functional additives; and 1-85% of water. The sum of weight percentage of the components is 100%. The prepared herbicidal has a significant synergistic effect, the efficacy of the herbicidal is improved, the active ingredient dosage is decreased in field, the production and use costs are reduced, and pesticide residue and environmental pollution are reduced. The herbicidal is composed of active ingredients of different mechanisms, increases the acting sites, and helps to overcome and delay the generation of weed drug resistance.
Description
Technical field
The invention belongs to the agricultural herbicide field, particularly a kind of aqueous suspension agent that contains mesotrione and clopyralid.
Background technology
Use chemical weed control and be during farmland weed is prevented and kill off the most effectively means, but the single chemical herbicide of long-term continuously high dose ground use, easily cause residual, environmental pollution and the problems such as weeds drug resistance and resistance development of weed killer herbicide.Development of new kind and rational mixture are the effective ways that addresses the above problem, and still, constantly soaring along with exploitation weed killer herbicide new varieties price has small investment, short built agent exploitation of lead time more and more is subject to domestic and international scientific research person's attention.
Mesotrione is trione compounds, is wide spectrum selective herbicide before a kind of bud that can suppress medical midbodies of para (ortho)-hydroxybenzoic acetone acid esters dual oxide enzyme (HPPD) and behind the seedling, can effectively prevent and treat main broadleaved herb and some grassy weeds.
Mesotrione is easily in plant xylem and phloem conduction, have action of contace poison and wholesomeness, the result shows through field control effectiveness test, 100 grams per liter mesotrione suspending agents have preferably control efficiency to corn field annual broadleaf weed and part grassy weed such as piemarker, three-coloured amaranth, lamb's-quarters, knotweed, barnyard grass, lady's-grass etc., and relatively poor to acalypha copperleaf and some grassy weed control efficiency.
Clopyralid is a kind of artificial synthetic auxin, and its chemical constitution and many natural auxins are similar, but have better persistence in the tissue of plant.It mainly the root by plant and leaf absorb then and in plant corpus, conduct, so its conductive performance is stronger.After the weeds dispenser, it is moved up and down and is transmitted to rapidly whole plant by the blade of plant or root absorption in plant corpus.Thereby the synthetic of DNA, RNA that the clopyralid of low concentration can stimulating plant and protein causes fissional out of control and unordered growth, causes at last restraining destroyed; The clopyralid of high concentration then can suppress division and the growth of cell.Can Controlling Weeds in Rape Fields, field annual broadleaf weed and the dark root perennial broadleaf weeds (composite family and pulse family weeds) such as corn, lawn.
