Abstract
The present invention is re-compounded herbicide of nicosulfuron and fluroxypyr, belongs to the field of farm chemical technology, and solves the technology problem of providing one kind of re-compounded herbicide capable of preventing and killing annual gramineous weed and broad leaved weed in corn field and being safe to corn and the successive crop. The re-compounded herbicide consists of nicosulfuron 2-6 wt%, fluroxypyr 5-15 wt%, dispersant 3-7 wt%, wetting agent 3-5 wt% and fine particle calcium carbonate for the rest. The present invention as one kind of ideal herbicide for corn field has wide herbicidal spectrum and obvious synergistic herbicidal effect.
Description
Technical field: the present invention relates to a kind of field weeding agent that is used for crops, is a kind of complex weedicide-nicosulfuron fluroxypyr that is used for behind the maize seedling.
Technical background: corn is China's important crops, also is important forage crop.In recent years, along with the development of industries such as livestock breeding, food processing, wine-making industry and biodiesel, the market demand of corn constantly increases.Last year, China's maize sown area reached 2,712 ten thousand hectares, was only second to paddy rice, wheat planting area, occupied the 3rd.Though the maize planting area lacks than wheat, output but surpasses wheat yield.The weeds of corn field are taken place general, and are of a great variety.The summer corn crop smothering takes place seriously in the Yellow River and Huai He River sea, and crop smothering generation area accounts for 82%～96% of this district's cultivated area, and wherein medium above hazard area reaches 64～66%.Corn is subjected to crop smothering the most serious seedling stage, the corn growth middle and later periods weeds little to the influence of output.When seedling stage, corn was subjected to weeds harm, plant was short and small, bar spire Huang, causes the middle and later periods corn growth bad, the serious underproduction.Therefore, the chemical control of corn field weed all broadcast the back seedling before and seedling after early stage two critical periods carry out.At present, the main medicament of weed killer herbicide that uses behind the domestic corn field seedling has: nicosulfuron, rimsulfuron, dicamba, thifensulfuron methyl, Brominal etc., mixture preparation have nicosulfuron and atrazine, dicamba and atrazine, nicosulfuron and piperazine humulone etc.
Along with the development of agricultural cience and farming techniques, one of the applying as the saving of labor, save time of chemical herbicide, volume increase and cost-effective effective measure.At present, the weed killer herbicide kind that is used to prevent and kill off corn field weed is more, and wherein representative kind then is that the beautiful farming of the former industry of Japanese stone is happy.But because of its selling at exorbitant prices, therefore, it is applied and is subjected to certain restriction.
Fluroxypyr is good foliar herbicide, and most of broad leaved weeds are had good preventive effect.But it is invalid to grassy weed, therefore, uses the harm of all weeds of the uncontrollable field of fluroxypyr separately.
Summary of the invention: technical problem to be solved by this invention is: provide a kind of and can prevent and kill off the corn field grassy weed, can prevent and kill off broad leaved weed again, to corn safety, and succession crop is not had the nicosulfuron fluroxypyr complex weedicide of influence.Its technical scheme is: a kind of nicosulfuron fluroxypyr complex weedicide is characterized in that: it is made by the raw material and the auxiliary agent of following quality percentage composition: nicosulfuron 2～6, fluroxypyr 5～15, dispersant 3～7, wetting agent 3～5 and fine particle calcium carbonate complement to 100.
Above-mentioned dispersant is any among D-425, NNO, MF and the SOPA.
Above-mentioned wetting agent is any among K12 and the LS.
Above-mentioned fine particle calcium carbonate is any in white carbon black, diatomite and the precipitated calcium carbonate.
Above-mentioned filler is any in white carbon black, diatomite and the precipitated calcium carbonate.
Its preparation method is: with above-mentioned raw material and the fully mixing of auxiliary agent warp, comminution by gas stream, mixing and screening, can make nicosulfuron fluroxypyr complex weedicide product.
Its technique effect is: weed killer herbicide of the present invention shows by the field control effectiveness test in 2 years, in 3～7 leaf phases of corn, weeds 1～5 leaf does not wait the phase, adopt weed killer herbicide dosage 100,120 of the present invention, 150ml/mu, converting water sprays for 40 kilograms/mu, 10, range estimation corn safety of 30 days and maturing stage and weeds preventive effect, surveyed all preventive effects, result such as following table in 10,30 days:
| Handle g/667m 2 | Grassy weed | Broad leaved weed | Nutgrass flatsedge | |||
| 10d behind the medicine | 30d behind the medicine | 10d behind the medicine | 30d behind the medicine | 10d behind the medicine | 30d behind the medicine | |
| 100 | 80 | 93 | 90 | 100 | 92 | 100 |

| Nicosulfuron | 85 | 95 | 20 | 40 | 95 | 100 |
| Fluroxypyr | 0 | 0 | 100 | 100 | 0 | 0 |
By range estimation, corn is not seen symptom of chemical damage from the dispenser to the maturing stage, to corn safety.The preventive effect of weeds reached more than 80% in 10 days, reached more than 90% in 30 days, increase along with dosage, preventive effect obviously strengthens, can reach good herbicidal effect at corn field 100 gram/mus, compare with wherein a kind of active ingredient of independent use, enlarged and killed the grass spectrum, a dispenser can be controlled the weeds in the crop whole growth phase, and not only herbicidal effect is remarkable, and environmentally friendly, second stubble crop there is not influence, pollution to environment is little, to people, animal, birds and beneficial organism safety, helps keeping ecological balance.Simultaneously, owing to do not have antagonism between the weed killer herbicide two component active ingredients of the present invention, so synergistic effect is remarkable.In addition, weed killer herbicide of the present invention adopts physical method processing, and production technology is simple, and three-waste free discharge in the production process has no adverse effects to ecotope.It is the desirable complex weedicide of present control efficiency.
