Abstract
The invention relates to a complex herbicide for treating stems and leaves of rice, and belongs to the technical field of agricultural pesticides. The invention provides a complex herbicide for stems and leaves of a rice field, which not only can prevent and remove grassy weeds such as Leptochloa chinensis in the rice field and the like, but also can prevent and remove broadleaf weeds, and is safe to rice and has no influence on succeeding crops. The technical key point is that the complex herbicide comprises the following raw materials and auxiliary agents in part by weight: 5 to 8 parts of cyhalofop butyl, 1.6 to 2 parts of carfentrazone-ethyl, 5 to 15 parts of 8207 emulsifying agent, 0.5 part of xanthan gum, 0.5 part of sodium benzoate and 100 parts of water. The complex herbicide has obvious weeding effect, and is superior to two single agents; simultaneously, the complex herbicide is wide in weeding spectrum, can prevent and remove annual grassy weeds and broadleaf weeds, can prevent and remove the weeds in the whole growth period of the rice by once application, has no influence on the following crops, and is the ideal herbicide currently.
Description
Technical field:
The present invention relates to a kind of field weeding agent that is used for crops, especially for the complex weedicide of stems and leaves of rice processing.
Technical background:
Paddy rice is not only the main cereal crops of China, also is one of world's staple food crop.Near in the world half population comprises the population in almost whole East Asia and Southeast Asia, all is food with rice.Production spreads all over each continent except that the South Pole.Eighties of last century late period, about 4,000 hundred million kilograms of world's rice annual production average out to, about 1.45 hundred million hectares of cultivated area.China's rice growing face accounts for 1/4 of national cereal crops, and annual about more than 3,500 ten thousand hectares, output then accounts for over half.No matter cultivated area and output all rank first in China cereal crops.The rice field of all rice workspaces of China always has a large amount of weeds to take place.Medium crop smothering area accounts for more than 46% of total cultivated area, and wherein serious injured area is more than 11.5%, and loss in every year grain is more than 200 hundred million kilograms thus.Therefore, the usage ratio of domestic water herbicides for use in paddy almost reaches 100%, and its dosage is very big.
Along with the development of agricultural cience and farming techniques, one of the applying as the saving of labor, save time of chemical herbicide, cost-effective strong well stimulation.At present, the rice herbicide kind is more, and wherein representative having prevented and kill off the third careless amine, butachlor, dichloro quinolinic acid, the benthiocarb of grassy weed and prevented and kill off broad leaved weed and the bensulfuron-methyl of sedge weed, pyrazosulfuron etc.These weed killer herbicides are sealing weed killer herbicide before the bud substantially, and are undesirable to the weeds effect of having emerged.Paddy field seedling rear defence is few except that the medicament kind of annual weed at present.
Summary of the invention
Technical problem to be solved by this invention is: can prevent and kill off the paddy field annual gramineous weed after a seedling is provided, can prevent and kill off broad leaved weed again, and succession crop not had the complex weedicide that stems and leaves of rice is handled that is used for of influence.
Its technical scheme is: a kind of complex weedicide that is used for the stems and leaves of rice processing, it is characterized in that: it is made by the raw material and the auxiliary agent of following weight parts: cyhalofop-butyl 5～8. profluazone 1.6～2,8207 emulsifier 5-15, xanthans 0.5, Sodium Benzoate 0.5, water complements to 100.
Weed killer herbicide of the present invention has tangible advantage, and it mainly shows:
1, do not have antagonism between weed killer herbicide two components of the present invention, synergistic effect is remarkable.
2, Fa Ming weed killer herbicide compares with using wherein a kind of active ingredient separately, enlarged to kill the grass spectrum, and a weeding, promptly the no weeds of controlled whole growth season joint endanger, and herbicidal effect is remarkable.
3, weed killer herbicide of the present invention is that cauline leaf is handled weed killer herbicide, sees grass back dispenser, and medicine removes to grass, has overcome the blindly defective of dispenser of Herbicidal agent, can be the peasant and reduces unnecessary medication spending.
4, weed killer herbicide effective dose of the present invention is low, a weeding, i.e. and the no weeds harm of controlled whole growth season joint, therefore little to the pollution of environment.
5, weed killer herbicide of the present invention belongs to the low toxicity product, to people, animal, birds and beneficial organism safety, helps keeping ecological balance.
6, weed killer herbicide production technology of the present invention is simple, adopts physical method processing, and three-waste free discharge in the production process has no adverse effects to ecotope.
7, weed killer herbicide of the present invention is advanced in the world Water-borne modification formulation, and is environmentally friendly.
Weed killer herbicide of the present invention shows by the field control effectiveness test in 2 years, after Direct-seeding Rice 3-4 leaf phase or rice transplanting are lived, 1～5 leaf phase of weeds, utilizes weed killer herbicide dosage 80,100 of the present invention, 120ml/667m
2, convert water and spray for 40 kilograms/mu, 10,35 days and maturing stage range estimation rice safety and weeds preventive effect, surveyed all preventive effects, result such as following table in 10,35 days:
By range estimation, paddy rice does not see symptom of chemical damage from the dispenser to the maturing stage, to rice safety.The preventive effect of weeds reached more than 80% in 10 days, reached more than 90% in 35 days, and along with the increase of dosage, preventive effect obviously strengthens, at paddy field 80ml/667m
2Can reach good herbicidal effect, a dispenser can be controlled the weeds in the crop whole growing, and second stubble crop is not had influence, is the desirable complex weedicide of present control efficiency.
Concrete embodiment:
Embodiment 1.In the high speed shear mixing kettle, add the 6kg cyhalofop-butyl successively, the 2kg profluazone, 8kg emulsifier 8207,0.5kg thickener xanthans, 0.5kg preservative sodium benzoate, water complements to 100kg, through Over emulsfication, homogenize, detects, pack, can make the aqueous emulsion product of complex weedicide of the present invention.
Embodiment 2.In the high speed shear mixing kettle, add the 7kg cyhalofop-butyl successively, 1.8kg profluazone, 10kg emulsifier 8207,0.5kg thickener xanthans, 0.5kg preservative sodium benzoate, water complements to 100kg, through Over emulsfication, homogenize, detects, pack, can make the aqueous emulsion product of complex weedicide of the present invention.
Embodiment 3.In the high speed shear mixing kettle, add the 8kg cyhalofop-butyl successively, 1.6kg profluazone, 15kg emulsifier 8207,0.5kg thickener xanthans, 0.5kg preservative sodium benzoate, water complements to 100kg, through Over emulsfication, homogenize, detects, pack, can make the aqueous emulsion product of complex weedicide of the present invention.
