Description
Technical field
The invention relates to a kind of purposes and using method thereof of weed killer herbicide, particularly about the sulfonylurea herbicide sulfometuronmethyl to the selectivity of economic crops cassava and sisal hemp and in this two kinds of crop Tanakas' using method.
Background technology
Sulfonylurea herbicide is that eighties of last century is the weed killer herbicide kind of new generation that the world of representative several top agricultural chemicals company releases the eighties with the du pont company, because of it has high activity, fabulous selectivity and extremely low toxicity and be described as " epoch-making new varieties " make chemical herbicide enter the new period of super-high-efficient development.
Sulfometuronmethyl is a typical member in the sulfonylureas family; its English common name is that its chemical name of Sulfometuron-methyl. is 2-[[[[(4; 6-dimethyl pyrimidine-2-yl) amino] carbonyl] amino] sulfonyl] methyl benzoate, have following chemical structural formula:
This compound by the du pont company research and development, is registered in the U.S. in nineteen eighty-three the earliest
[3](number of registration 352-401), formulation is sulfometuronmethyl 75% water dispersible granules, commodity are called " Oust ".It is weed control in uncultivated area weeding, coniferous tree tending [after young plantation and the industrial lawns such as woodland weeding and Bermuda grass that the scope of application of this weed killer herbicide is recommended by E.I.Du Pont Company.In other words, the selectivity of the sulfometuronmethyl of Du Pont's identification is to coniferous tree
[4,5]And Bermuda grass
[6]Selective.Domestic experimental study has confirmed this point
[7-11]
Test in a large number and promote the use of and show, sulfometuronmethyl has and kills grass spectrum, high activity of weeding and extremely low toxicity very widely, and the pedo relict activity of long period can be provided.Therefore it is a kind of outstanding forest land and uncultivated area weed killer herbicide.We make great efforts to enlarge its scope of application always, make the bigger effect of its performance.Our test shows that except the selectivity of sulfometuronmethyl to coniferous tree and Bermuda grass that above-mentioned E.I.Du Pont Company finds, sulfometuronmethyl has good selectivity equally to many kinds of broad-leaved evergreens
[12]For example, with concentration be 500ppm the sulfometuronmethyl aqueous solution to the high Piao Shu of 50cm, May treelet seedlings such as tea, extra large mango, short preface profit south, acacia confusa, longan, lichee, kamuning directly spray, observe half a year continuously then, showing does not have any harmful effect to the growth of treelet.Our test shows that also sulfometuronmethyl is to bamboo grows also high safety
[13]Therefore, by our work, the scope of application of sulfometuronmethyl has been enlarged further.
But it is selective to economic crops cassava and sisal hemp up to now, to cross sulfometuronmethyl without any bibliographical information both at home and abroad.
Summary of the invention
Main purpose of the present invention provides selectivity and the using method thereof of a kind of sulfometuronmethyl to cassava and sisal hemp, and sulfometuronmethyl is a kind of cassava and sisal hemp to be had high safety, and herbicidal effect both efficiently, economic weed killer herbicide new varieties.
The object of the present invention is achieved like this, we pass through field experiment, find first that at home and abroad sulfometuronmethyl has fabulous selectivity to economic crops cassava and sisal hemp, thereby sulfometuronmethyl can be used as selective herbicide and prevents and kill off various weeds with being used for cassava and sisal hemp.
Described sulfometuronmethyl is used for cassava ground weeding, but all medications of each stage of before cassava is broadcast the back seedling, growing to the back of emerging; Administration time is that the weeds sprouting period is to the young tender phase; Consumption is 75～300 gram/hectares, makes flushing liquor by 450～750 kilograms of/hectare water consumptions and makes directed even spraying to soil table and weeds.
Described sulfometuronmethyl is used for the weeding of sisal hemp nursery lot, medication when the sisal hemp seedling grows 3～5 blades; Administration time is the weeds sprouting period to the young tender phase, and consumption is a 30-45 gram/hectare; Make flushing liquor by 450～750 kilograms of/hectare water consumptions and make directed even spraying to soil table and weeds.
Described sulfometuronmethyl is used for the ground weeding of above the average age for marriage sisal hemp, administration time be the weeds sprouting period to the young tender phase, consumption is 75～450 gram/hectares; Make flushing liquor by 450～750 kilograms of/hectare water consumptions, make directed even spraying to the face of land and weeds.
Characteristics of the present invention are: cassava and sisal hemp are the economic crops that are suitable in the torrid zone and subtropical zone plantation.Cassava is easily planted thick giving birth to, the soil of impoverishment tolerant arid, and damage by disease and insect is few, and the output height not only can provide food starch, and can be used as industrial chemicals and carry out deep processing, produces broad-spectrum modified starch and industrial alcohol.Particularly the cassava industrial alcohol is suitable for mixing as motor vehicle fuel with gasoline very much.Under the overall background of petroleum resources worsening shortages, this purposes has the important strategic meaning.
Sisal hemp then is the important source material that gunny products is used in fishery and navigation.Hawser and the fishing net intensity made with it are big, and sea water resistance soaks, and has important industrial value.
High temperature and rainy in the torrid zone and subtropical zone are annual basically, weed growth is luxuriant, and the crop smothering on cassava and sisal hemp ground is serious.But up to now, also be not suitable for the chemical herbicide kind that these two kinds of crops are used.The still main conventional approach by artificial weeding of peasant is struggled with weeds.Therefore, it is significant that research and development are suitable for the weed killer herbicide kind used on cassava and sisal hemp ground.We find first that by experiment sulfometuronmethyl has fabulous selectivity to cassava and sisal hemp.This discovery has important significance for theories and great practical value.
The invention will be further described below by concrete experiment.
1) by experiment, finds that first sulfometuronmethyl has fabulous selectivity to cassava.In other words, cassava has extremely strong drug resistance to sulfometuronmethyl.Specific practice is: adopt the sulfometuronmethyl soup of variable concentrations, in the different phase of cassava growth, even spraying to soup begins trickling on the cauline leaf of cassava seedling or above the average age for marriage plant, observes the growing state of cassava then.Experimental result is as shown in table 1.
Table 1. sulfometuronmethyl is to the safety experiment result of cassava
| The cassava vegetative stage | Liquor strength (ppm) * | Experimental result |
| Before emerging after broadcasting | 200 | The even spray liquid of Xiang Tubiao and weeds is moistening to soil table, observes the cassava situation of emerging then.In a week after the dispenser, cassava normally grows.Continue observation one month, growth is normal. |
| The cassava seedling that 5cm is high | 100 | Evenly be sprayed to soup to cassava seedling cauline leaf and begin trickling, observe its growing state then.After 10 days, cassava is long to 10cm, and all are normal.Continue observation two months, all are normal. |
| The above the average age for marriage cassava plant that 210cm is high | 500 | Evenly spray liquid is observed its growing state then to beginning trickling on the cauline leaf of cassava plant.After one month, sprayed not medication high of the long ratio of the cassava of soup, came along fine.Gather in the crops the cassava stem tuber end of the year, output is normal, and the tapioca quality that makes is normal. |
*Is 100～400ppm on cassava ground with the employed liquor strength of sulfometuronmethyl management of weeds.
2) by experiment, find that first sulfometuronmethyl has good selectivity to sisal hemp.In other words, sisal hemp has very strong drug resistance to sulfometuronmethyl.Specific practice is: adopt the sulfometuronmethyl soup of variable concentrations, carry out safety experiment on sulfometuronmethyl seedling and above the average age for marriage plant.Experimental result is as shown in table 2.
Table 2. sulfometuronmethyl is to the safety experiment result of sisal hemp
| The sisal hemp vegetative stage | Liquor strength (ppm) | Experimental result |
| The seedling that 5～10cm is high, 3～5 blades | 50 | Evenly spray liquid is observed its growing state then to beginning trickling on the sisal hemp seedling leaves.Continuous Observation 2 months, growth is normal. |
| The seedling that 5～10cm is high, 3～5 blades | 100 | Evenly spray liquid is observed its growing state then to beginning trickling on the sisal hemp seedling leaves.Continuous Observation 2 months, growth is normal. |
| The sisal hemp vegetative stage | Liquor strength (ppm) | Experimental result |
| The seedling that 5～10cm is high, 3～5 blades | 200 | Evenly spray liquid is observed its growing state then to beginning trickling on the sisal hemp seedling leaves.Indivedual seedling leaves foxiness occur behind the two weeks, have illustrated that poisoning takes place. |
| The one-tenth sisal hemp in age that grew 3 years, high about 1.5m | 200 | Evenly spray liquid is observed its growing state then to beginning trickling on sisal hemp leaf.Continuous Observation 2 months does not see that any anomaly takes place. |
3) adopt 70% sulfometuronmethyl soluble powder to carry out the weeding test in cassava and sisal hemp ground, the result is as shown in table 3.
Table 3. weeding result of the test gathers
| Crop and vegetative stage | Dispenser dosage gram (active ingredient)/hectare | Weeds kind and growing state | Experimental result |
| Become the sisal hemp in age, high 130～150cm grows fine | 420 | 100% cover weeds on the vacant lot between the sisal hemp plant, natural plant height 30～80cm, based on broadleaved herb, grass family and sedge weed take second place, count about 30 surplus kind. | Make the 600ppm soup, to the even directed spraying of weeds cauline leaf.Weeds promptly have the symptom of obviously being injured after one week; Most of weeds are withered after one month, and all weeds are withered after two months.On original vacant lot, newly grow the floor file broomcorn millet and cover whole vacant lots.The sisal hemp growth is normal. |
| Above the average age for marriage cassava, high 150-170cm grows fine | 420 | In the ranks vacant lot all covers weeds, and is multiple with other weeds based on Japanese grass, natural plant height 30～100cm. | Make the 600ppm soup, to the even directed spraying of weeds cauline leaf.Weeds promptly have the symptom of obviously being injured after one week, and are all withered in two months, after 8 months, still do not have new weeds and grow.The cassava growth is normal. |
| Crop and vegetative stage | Dispenser dosage gram (active ingredient)/hectare | Weeds kind and growing state | Experimental result |
| 3～5 blades of sisal hemp seedling, high 5～10cm grows fine | 45 | In the ranks vacant lot all covers weeds, and single, double cotyledon weeds mix and give birth to natural plant height 5～15cm. | Make the 70ppm soup, do directed spraying (as far as possible avoiding the sisal hemp seedling) to the weeds cauline leaf.Behind the two weeks, symptom appears significantly being injured in weeds.After one month, most of broadleaved herb is withered, and all weeds are withered after two months.The sisal hemp seedling grows fine. |
The experimental result of being enumerated by table 1, table 2 and table 3 is as can be known:
(1) sulfometuronmethyl has fabulous selectivity to cassava, and is also very good to the selectivity of sisal hemp, and therefore, sulfometuronmethyl can be used as selective herbicide and prevents and kill off various weeds with being used for cassava and sisal hemp.Cassava belongs to evergreen shrubs, so sulfometuronmethyl has fabulous selectivity to it, and is also just not at all surprising! Sisal hemp belongs to evergreen perennial plant, has very strong drug resistance also just to be understood that to sulfometuronmethyl.
(2) sulfometuronmethyl 70% soluble powder is the novel formulation (seeing CN1279028C for details) that we adopt special process development, is used for the ground weeding of cassava and sisal hemp, demonstrates high activity of weeding, kills grass spectrum, fabulous herbicidal effect and long lasting period widely.Especially surprisingly, after original weeds are removed with sulfometuronmethyl in sisal hemp ground, grow new grass seeds " floor file broomcorn millet " again, it is crawled in the face of land, regulates the humidity of the gentle surrounding air in ground, causes the microclimate environment that helps the sisal hemp growth.Therefore, the appearance of floor file broomcorn millet is highly significant to sisal hemp.
Following example has been made further instruction to the present invention.
