Abstract
A kind of herbicide which can be used in corn field and soybean field simultaneously contains dimethachlor and metribuzin in wt. ratio 1/6 to 1/2. It is effective in killing gramineous weed and most kind of broad leaved weed. The advantages of this herbicide includes safe to crops, long effect duration of 8-12 weeks, no effect to the followed crops and low in cost.
Description
The present invention relates to contain the mixture of compound Acetochlor and compound piperazine humulone, particularly relate to the mixture that can be used as corn field, the weeding of soybean field simultaneously.
The known weed killer herbicide that does not also have at present to be used for suitable the time corn field, soybean field.The weed killer herbicide that is used for corn field mainly contains 1. Acetochlors, be used to prevent and kill off corn field grassy weed and part small-sized seed breeding annual broadleaf weed, narrow because of its herbicidal spectrum, thereby have only to match and use the weeds harm that could control corn field effectively with other weed killer herbicide or artificial weeding.2. atrazine, herbicidal effect is good, but the longevity of residure is long, and succession crop is caused poisoning, causes the underproduction, has a strong impact on the crop rotation of science, and then can limit the further raising of agriculture production benefit.3. atrazine plus acetochlar is that the mix preparation of Acetochlor and atrazine contains 50% atrazine because of it, thereby is restricted on using.4. drag-line, it is narrow that it kills the grass spectrum, and carcinogenesis is arranged, thereby be subjected to strict restriction on using.
The weed killer herbicide that is used for the soybean field mainly contains: 1. Acetochlor, drag-line can be used for the preceding soil treatment of big bean seedlings, and the grass spectrum is narrow extremely, must could control beans field crop smothering effectively with other herbicide mixture.Cover grass energy, Sethoxydin, surely kill, quizalofopethyl is imported product, it is single to kill the grass spectrum, must with other herbicide mixture, could control beans field crop smothering effectively.3. grand, the Imazethapyr of beans sulphur, clomazone herbicidal effect are good, but the medicament longevity of residure is long, can cause serious poisoning to various crop.
Soybean and corn intercrop are China's main tillage methods in vast zone.The objective of the invention is to seek a kind of weed killer herbicide that can be used for corn field, soybean field simultaneously, broad weed-killing spectrum to crop safety, does not influence second stubble crop, and cost is low, and is easy to use, and a drug can solve the weed killer herbicide of crop crop smothering in time of infertility problem.
For achieving the above object, the solution of the present invention's employing is: 1. the piperazine humulone is the chemical herbicide that is used for the soybean field.The present invention once screened the fine herbicide that is respectively applied for corn field, soybean field, evidence, having only the piperazine humulone can be used safely in corn and soybean simultaneously does and broadcasts back seedling pre-treatment, other medicament all shows in various degree has poisoning to produce to corn or soybean, thereby assert that the piperazine humulone not only can be used for the weeding of soybean field, and can be used safely in corn field and prevent and kill off broad leaved weed, thereby can prove that piperazine humulone and Acetochlor are used with can realize above-mentioned purpose.2. screen the good proportioning that Acetochlor and piperazine humulone are mixed.The present invention Acetochlor, piperazine humulone in different ratios and dosage at its safety to corn, soybean, the herbicidal effect of broadleaved herb, gramineous grass has been carried out field trial.Find out from test: it is poor that Acetochlor when representing with parts by weight/piperazine humulone shows as crop safety in the ratio more than 1/2, only under high dose, just grassy weed there is preventive effect preferably simultaneously, though it is and good in 1/6 following safety, but show not goodly, only under high dose, just show effect preferably the herbicidal effect of broad leaved weed.Acetochlor when thereby the optimal proportion that has found two kinds of mixed pesticides is represented with parts by weight/piperazine humulone=1/6～1/2.
Cream preparation embodiment:
Acetochlor, mix in the ratio of Acetochlor/piperazine humulone=1/6～1/2 when the piperazine humulone is represented with parts by weight, add homemade farming breast 2101, its weight is 1/5th of Acetochlor, piperazine humulone weight sum, add the molten Jie's Acetochlor of every energy, piperazine humulone again and be suitable for joining the organic solvent that breast uses as agricultural chemicals, its weight is 4/5ths of Acetochlor, piperazine humulone weight sum.They are all dropped in the preparation still, under normal temperature, mix, till the missible oil clarification.
Claims (3)
1, a kind of mixture herbicide contains compound component A and compound component B.It is characterized in that: component A is an Acetochlor, and B component is the piperazine humulone.Can be used for the weeding in corn field, soybean field.
2, according to the described weed killer herbicide of claim 1, it is characterized in that: when the content of component A, B component was represented with parts by weight, component A/ B component was 1/2～1/6.
3, according to the described weed killer herbicide of claim 2, it is characterized in that: when the content of component A, B component was represented with parts by weight, its preferable range was that component A/ B component is 1/2.7～1/5.3.
