The invention discloses a kind of herbicidal composition containing mesotrione, propisochlor and atrazine and preparation method thereof, pharmaceutical applications, it is related to herbicide technology field.The present invention contains active component mesotrione, containing active component propisochlor and containing active component atrazine, and weight accounting of the three in herbicidal composition is (1%~50%)：(34%~48%)：(0.3%~0.68%), preferably (4%~30%)：(35%~45%)：(0.3%~0.6%).The present invention to the accounting of mesotrione, propisochlor and atrazine three in herbicide by carrying out rational proportion, strengthen the property of medicine effect of herbicide, to corn safety, broad weed-killing spectrum, three's mixture is used for the annual gramineous weed and broadleaved herb for preventing and kill off corn field before seedling or after seedling, and the closing weeding phase in soil extends, and a season of dispenser one is harmless, there is preferable prevention effect, improve the security performance that herbicide uses.
Description
Technical field
The invention belongs to herbicide technology field, more particularly to a kind of containing mesotrione, propisochlor and atrazine
Herbicidal composition and preparation method thereof, pharmaceutical applications.
Background technology
Corn can cause short and small, bar spire Huang of plant etc., sternly in whole breeding time by different weeds, disease
The good harvest of corn is threatened again, and corn field weed occurs generally, and species is various, and corn field weed main weeds have lady's-grass, barnyard grass, dog
Tail grass, eleusine indica, Amaranthus retroflexus, purslane, acalypha copperleaf, rhizome of nutgrass flatsedge etc..Maize at Seedling Stage is most heavy by the harm of weeds, so weeds
Chemical prevention, which should be done a good job of it, broadcasts rear two critical periods of before seedling and after seedling early stage, weeds is administered using herbicide, on the one hand
Management of weeds is wanted, on the other hand must avoid causing damage to same field crop even succession crop again, this is just to the section of herbicide
Learn to use and propose very high requirement.
Mesotrione is before a kind of bud that can suppress medical midbodies of para (ortho)-hydroxybenzoic acetone acid esters dual oxide enzyme and after seedling wide spectrum selectivity
Herbicide, it can effectively prevent and treat main broadleaved herb and some grassy weeds.Mesotrione suspending agent is annual to corn field wealthy
Leaf weeds and part grassy weed such as piemarker, three-coloured amaranth, lamb's-quarters, knotweed, barnyard grass, lady's-grass etc. have preferable prevention effect, and to iron amaranth
Dish and some grassy weed prevention effects are poor.
Propisochlor is inner sucting conduction type selectivity preemergence herbicide, is mainly absorbed by weed bud.It is steady in soil
It is qualitative small, it is stable to light, it can be that edaphon is decomposed, succession crop is not influenceed.Suitable for dry crop prevent and kill off barnyard grass,
The broad leaved weed such as the annual gramineous weeds such as eleusine indica, lady's-grass, green bristlegrass and lamb's-quarters, Amaranthus retroflexus, piemarker, black nightshade.Isopropyl grass
The herbicidal effect of amine, can just be given full play under preferable soil moisture, suitable in covering with ground sheeting field, have the field of irrigation conditions with
And summer crop and southern dry land application.Propisochlor can only kill the weeds of rudiment, therefore should rest in before weeds are unearthed and apply
Medicine.
Atrazine is the selective before seedling of interior suction, after seedling closing herbicide.Based on root absorbs, cauline leaf absorbs seldom.Herbicide is made
With with the same Simanex of selectivity, easily eluted by rainwater to soil deeper, it is also effective to some deep root grass, but be also easy to produce poisoning,
Lasting period is also longer.Its herbicide controlling spectrum is wider, can prevent and kill off a variety of annual gramineaes and broad leaved weed.Suitable for corn, sorghum,
The dry crops such as sugarcane, fruit tree, nursery, forest land prevent and kill off lady's-grass, barnyard grass, green bristlegrass, nutgrass flatsedge, amur foxtail, knotweed, lamb's-quarters, Cruciferae,
Pulse family weeds, especially there is preferable selectivity to corn, also have certain inhibitory action to some perennial weeds.
Maize at Seedling Stage is also exactly many weeds germinations, the vigorous period of growth.Weeds and corn contention moisture, nutrient, light
According to and space, influence the normal growth of Maize at Seedling Stage.The weeding by way of manually drawing hoe, while the penetrating of soil can be improved
Property, there is drought-relief, waterlogging-preventing, but time-consuming efficiency is low.Chemical agent weeding saving of work and time, herbicidal effect is good, but
It is if improper use also can cause to cause harm to corn and its succession crop.Therefore, invention is a kind of containing mesotrione, propisochlor
With the herbicidal composition of atrazine and preparation method thereof, pharmaceutical applications, poisoning is reduced, removes weeds, realizes the height of crops
Production.
The content of the invention
It is an object of the invention to provide a kind of herbicidal composition containing mesotrione, propisochlor and atrazine and its
Preparation method, pharmaceutical applications, it is made that a kind of component is reasonable, and herbicidal spectrum is wide so as to produce, preventive effect is good, and dosage is few, is not likely to produce
The annual gramineous weed for preventing and kill off corn field before seedling or after seedling of poisoning and one kind of broadleaved herb are containing mesotrione, propisochlor
With the dispersible oil-suspending agent of herbicidal composition of atrazine.

In order to prevent and treat the annual gramineous weed of corn field before seedling or after seedling and broadleaved herb, inventor has carried out concentration
Experiment of the 35% dispersible oil-suspending agent of mesotrione propisochlor atrazine to corn field weed.Field main weeds have
Piemarker, lady's-grass, barnyard grass, iron amaranth and small lamb's-quarters, weed size is in the 2-4 leaf phases.Test medicine and dosage are that 35% mesotrione is different
The dispersible oil-suspending agent 150g/ mus of pretilachlor atrazine, 200g/ mus, 3.5% mesotrione wettable powder 120g/ mus,
The dispersible oil suspending agent 200ml/ mus of 72% propisochlor, the dispersible oil suspending agent 150ml/ mus of 38% atrazine.Using conventional spraying
Method.
The dispersible oil-suspending agent of mesotrione propisochlor atrazine of table 1 35% was to 7 days after corn field weed medicine
Strain preventive effect
The dispersible oil-suspending agent of mesotrione propisochlor atrazine of table 2 35% was to 20 days after corn field weed medicine
Strain preventive effect
The dispersible oil-suspending agent of mesotrione propisochlor atrazine of table 3 35% was to 20 days after corn field weed medicine
Fresh weight preventive effect
Result of the test shows：After the dispersible oil-suspending agent 200g/ mu medicines of 35% mesotrione propisochlor atrazine
20 days average the strain preventive effects and fresh weight preventive effect to piemarker, lady's-grass, barnyard grass, iron amaranth and small lamb's-quarters are all remarkably higher than the nitre of comparison medicament 35%
The dispersible oil-suspending agent 150g/ mus of sulphur humulone propisochlor atrazine, 3.5% mesotrione wettable powder 120g/
Mu, the dispersible oil suspending agent 200ml/ mus of 72% propisochlor, the dispersible oil suspending agent 150ml/ mus of 38% atrazine, illustrate nitre sulphur grass
