Abstract
The invention belongs to the field of pesticide mixing, and discloses a composition of corn field herbicides. The composition is a suspoemulsion, a water suspending agent or an oil suspending agent composed of A, B and C herbicide compounds serving as active ingredients, and the active ingredient content of the composition is 5 to 60 percent; A is mesotrione, B is one or more of triazine herbicides, and C is one or more of amide herbicides, wherein the composition contains one herbicide compound A, at least one herbicide compound B selected from the following compounds and at least one herbicide compound C selected from the following compounds; and according to the formula, the composition is ground under high pressure, emulsified and dispersed into the suspoemulsion, the water suspending agent or the oil suspending agent according to different proportions, and is used for preventing and killing weeds in corn fields at the post-emergence stage.
Description
Technical field
The invention belongs to the mixed pesticide field, relate to active principle (A) and at least a specific herbicides compounds (B) and at least a specific herbicides compounds (C) and form suspension emulsion, aqueous suspension agent, oil suspending agent.
Background technology
Along with the adjustment of the structure of agricultural production, the expansion that further develops and export of livestock breeding significantly increases the demand of corn, and domestic 80% above corn is mainly used in feed at present, and starch, alcohol, monosodium glutamate are processed and pharmacy etc.Along with the reinforcement of environmental protection, reduced motor vehicle exhaust emission in recent years, and used, thereby the development ethanol industry becomes trend with ethanol instead of part gasoline.Its primary raw material adopts corn, will promote the expansion plantation of corn like this, has more potentiality to be exploited so it is compared in other crop.
Corn is one of three generalized grain crops in China, and sowing area is 2,586 ten thousand hm
2, per unit area yield has only 4880kg/hm
2, the american corn sowing area is 2,854 ten thousand hm a little more than China
2, per unit area yield is higher nearly 1 times than China, is 8391.8kg/hm
2, except other reason, the accurate application of weed killer herbicide is a key factor.It is 5,620,000 hm2 that China's corn field herbicide is used area, only account for the last 1/4, China's corn field herbicide kind only has atrazine, piperazine humulone, alachlor, Acetochlor, isopropyl methoxalamine, propisochlor, thifensulfuron methyl, nicosulfuron, trefanocide, 2, kind surplus 4-D, glyphosate, the paraquat etc. 10, wherein long residual effect weed killer herbicide atrazine consumption is excessive, succession crop is impacted, at China's crops cropping index height, under crop rotation, the interplanting complicated situation, the weed killer herbicide that this kind is single uses for a long time, exists huge hidden danger.In addition, often take place in China under the situation of arid, the effect of herbicides instability relevant with rainfall, arid during medication, drug effect is very poor or invalid, meets heavy rain sometimes, causes poisoning again.
Summary of the invention
The composition that the purpose of this invention is to provide a kind of corn field herbicide, found out the effectiveness that Herbicidal combinations showed of compound (A) and some specific compound composition or the stack that activity level has exceeded each composition activity, this exercising result can be described as synergistic effect.
The present invention has synergistic effect according to compound (A) and the Herbicidal combinations that some specific compound forms, and therefore provides one group of herbicidal composition, finds the new purposes of composition simultaneously.
For achieving the above object, the technical solution used in the present invention is:
A kind of composition of corn field herbicide,
It is to be suspension emulsion (SE), aqueous suspension agent (SC) or the oil suspending agent (OF) that active ingredient is formed with three kinds of herbicides compounds of A+B+C, and the effective component content of composition is 5-60%;
A is a mesotrione, and B is one or more in the triazine herbicide, and C is one or more in the acetamide-group herbicides;
Wherein contain a kind of herbicides compounds A, at least a herbicides compounds B and at least a herbicides compounds C that is selected from following compound that is selected from following compound.
Described triazine herbicide B is one or more in atrazine, Garagard or the cyanazine; Described acetamide-group herbicides C is one or more in propisochlor, isopropyl methoxalamine, Acetochlor, the alachlor;
Wherein compd A, B, C are (1～20) based on the parts by weight ratio of active component: (1～40): (1～40) is preferably 1: (2～8): (2～8).

Described oil is a kind of in mineral oil machine oil, diesel oil, lubricating oil or vegetable oil soybean oil, levant cotton oil, the peanut oil.
The composition that the present invention describes can be the finished product preparation form, and promptly various materials mix in the finished product.Also can be each composition (active matter) provides with preparation separately, directly mixes before use and uses.
Described composition is used for the corn field postemergence weed control.Be used for early stage dispenser behind the seedling, can carry out the cauline leaf spraying to the weeds of 2-5 leaf phase and handle.
The present invention has following advantage:
1. compound (A) mesotrione is a herbicides special behind the corn field seedling, and broad leaved weed in the corn field and part grassy weed are had significant preventive effect, and is good to the corn safety.Because mesotrione is active high to broad leaved weed, only good to part grassy weed activity, after it and compound (B) triazine herbicide are mixed, have good synergistic effect, because it is mesotrione is very fast in degradation in soil, relatively poor simultaneously to the grassy weed preventive effect that the later stage occurs, the applicant has added compound (C) acetamide-group herbicides, compound (A), (B), (C) interact like this, have complementary advantages, and have controlled the corn growing season weeds in field.
So compound (A), (B), (C) are made suspension emulsion, aqueous suspension agent, oil suspending agent after mixing, can enlarge and kill grass spectrum, raising herbicidal effect, prolong effective drug duration, reduction is to the poisoning of crop, delay the drug-fast generation of weeds and the succession of community, reduce dosage, reduce residual activity, reduce environmental pollution; Simultaneously a drug is a controlled corn growing season weeds in field, overcome seedling before medication be subjected to the bigger defective of weather effect, save time, laborsaving, economical, reduce farmer's burdens.
2. Herbicidal combinations provided by the present invention has broad weed-killing spectrum, long characteristics of lasting period, the effectively common single broadleaf weed in control of maize field.To grassy weed as: the preventive effect of barnyard grass grass, lady's-grass, green foxtail etc. is significantly higher than the preventive effect of compound alone (A); and reduced the amount of application of every kind of active substance; this characteristic has important ecological significance; it can delay the drug-fast generation of weeds and the succession of community, and the protection environment is also had heavy meaning.
