Abstract
A kind of new method of optionally controlling weed growth in the farmland is used the weeding sulfonyl urea derivates exactly before seed sprouting, be included in the sowing division the most close seed the place and simultaneously seed is used herbicidal active compounds.
Description
The present invention relates to a kind of new herbicidal methods, before crops emerge, optionally control weed growth exactly.Way traditional on the agricultural is to use the whole cultivation area of herbicide treatment before seed sprouting and after emerging.In order to control or to prevent that damage by disease and insect from spreading the infringement crop, the long-term method that adopts, wrap up in fertilizer and ditch dug with a plow is used bactericide or insecticide as the surface of the seed, comparatively favourable to the reduction expense, but this method is used for weed killer herbicide, people have begun to recognize, it only is suitable for volatile weed killer herbicide, is used for soybean and cotton, as 5-ethyl dipropyl thiocarbamate, be called for short EPTC, (see USP NO4,272,920 and DaLe, Weed Research 23 is 63-68(1983) in the Lucerne).
This method principle is moved to other commodity weed killer herbicide be used for other crop, as cereal, be impossible, such as weed killer herbicide 5-(2,4-dichlorophenoxy)-and 2-nitrobenzoic acid methyl esters (Bifenox), 3-(3-chloro-4-tolyl)-1,1-dimethyl urea (Chlortoluron) or N-(1-second propyl group)-3,4-dimethyl-2,6-dinitroaniline (N-(1-second propyl group)-2,6-dinitro-3,4-dimethylaniline) etc.Test shows that they are harmful to crop, and weeds are not but had obvious influence.EPTC and other weed killer herbicide (Chlortolurn or N-(1-second propyl group)-2,6-dinitro-3,4-dimethylaniline) between difference between the effects may be because EPTC spreads sufficient cause with vapor form in soil.This is the not available characteristics of other weed killer herbicide.(see Weed Science 1983, Vol 31,103-108).
Surprisingly, find the weed killer herbicide of those difficult volatilizations recently,, also can be used for seed treatment and be used for the seed ditch dug with a plow, reach the purpose of selecting the control weeds as sulfonylurea.Therefore, the present invention proposes optionally to control the method for weeds in field growth, uses the weeding sulfonyl urea derivates simultaneously to seed with at the most close seed place in the cultivation area.So-called use the weeding sulfonylureas, refer to this type of weed killer herbicide is discharged in seed ditch dug with a plow soil at the most close seed place, or around seed in the narrower limited district and sowing with the pretreated seed of weed killer herbicide.The activity of weeding thing can be attached to the surface of the seed, or penetrates the surface of the seed.
The surface of the seed bag fertilizer has proved a kind of method that is particularly suitable for the preliminary treatment seed, and sterilization of the surface of the seed bag or insecticide active substance also are well-known methods in the premodern agriculture technology.When using the weeding sulfonyl urea derivates, can be added on the seed in the fertile device of large-scale the surface of the seed bag with solid or liquid preparation, when active substance reached predetermined concentration and be uniformly distributed on the seed, handling promptly, announcement finished.
Method provided by the invention had both been simplified the field operation, saved the weed killer herbicide consumption again, thereby had reduced the dispenser labour cost, had alleviated the pollution of using insecticide to cause; Like this, seed and weeding sulfonyl urea derivates can once-through operation impose on the field.Because the weed killer herbicide occupation mode is special, can accomplish that only removing very near the weeds at seed place, needn't keep the active concentration of weed killer herbicide at whole growing area, so just save the weed killer herbicide consumption.
During use, carry acyl processing seed or seed ditch dug with a plow with weeding sulphur before being better than sowing most, make quantity of active material reach 0.001 kilogram/hectare to 1 kilogram/hectare scope; Handling kind of a period of the day from 11 p.m. to 1 a.m, see seed density size, in the per kilogram seed, to the weed killer herbicide of the present invention's preparation, its active component quantity is between 0.01～100 gram.What of active component preferably will be regulated according to the degree of required control weeds.For crops, the weed killer herbicide consumption does not have critical value, can change in the scope of broad.For some crops, not exclusively remove weeds, may be favourable on the contrary, because can alleviate the soil erosion like this.In this case, the weed killer herbicide consumption should be selected to such an extent that just can guarantee to weaken the fearful degree of competing of weeds in the seed sprouting initial stage; Especially to weaken the fearful degree of competing of the most close seed place weeds, because in the fearful comparatively sensitivity of striving of this stage seed bud seedling to weeds.

Do by the inventive method, obvious economic, because the sowing and the preceding weeds control of sprouting only need once-through operation, like this with regard to available custom-designed seed drilling machine, weed killer herbicide is directly broadcast into the seed ditch dug with a plow with untreated seed, perhaps, sow with the pretreated seed of weed killer herbicide as traditional method.
Adopt this method, the weeding sulfonylureas spread to seed in the soil around, form the Wu Cao district near making the seedling of germination.In the Wu Cao district, because the effect of weed killer herbicide, prevent fully or suppressed weed growth, weeds can't be striven with the seedling of crop is fearful.In the seed ditch dug with a plow, annular Wu Cao district merges together each other, makes seed ditch dug with a plow both sides form the weeds inhibition zone; In random sowing division, aspermous place may be weedy; In the seed compact district, or the little place of ditch dug with a plow line space, the growth of weeds can be suppressed fully.
Under the unfavourable weather condition, make in this way and aspect ecological, also can be beneficial to, because the topped or withered undesirable root of weeds brings back to life, all can help to prevent the soil erosion and arid, this also is because the fearful weeds that strive just are suppressed just now on the ground of very approaching germination crop.In addition, because also being applicable to not have to cultivate, the inventive method plants, so the soil cultivation expense may be lower.
Below further specify the inventive method for example.
Biology is given an example:
Test method is introduced:
In capacity 100 ml flasks, put into the weed killer herbicide of 30 gram wheats and 23 gram barley seeds and preparation respectively, rotation vibrations flask carries out the processing of the surface of the seed bag weed killer herbicide then.Herbicidal activity thing consumption is 16,13,8.1,6.5,4.07,3.25,1.95,1.63,0.98,0.81 or 0.41 milligrams of active substances to per 30 gram wheats or 23 gram barleys.
The seed of handling is broadcast (long 25 centimeters, wide 17 centimeters, high 12 centimeters) in the vinyl disc that sandy loam is housed with weed seed.Each each dish is broadcast weed seed, 18 wheat seeds (being equivalent to 180 kilograms/hectare) and 14 barley seeds (being equivalent to 150 kilograms/hectare) of equal number respectively.Like this, just according to required processing seed number decision, per hectare uses 100,80,50,40 respectively to the quantity of weed killer herbicide, 25,20,12,10,6,5 or 2.5 grams.After planting, regularly water, keep 22～25 ℃ of greenhouse temperatures and relative moisture 50～70%.After 38 days, plant according to the observation suppresses situation, with the sesamoid result's contrast of being untreated, estimates the effect of weed killer herbicide.
Result of the test compares with the sample that is untreated, and represents that with percentage plant growing suppresses degree.
Dead and ablastous plant growing inhibition degree are 100%, and untreated check plant growth inhibition degree is 0%.
A), the weed killer herbicide that is used for seed treatment is N-(2-(2-chloroethoxy) phenyl sulfonyl)-N '-(4-methoxyl group-6-methyl isophthalic acid, 3,5-triazinyl-2) urea, but be made into 1% wet powder.
