Method of increasing the resistance of sugar beet to fetotoksicheskoe effects of the herbicide roundup

 

The invention relates to agriculture, namely, to increase the resistance of plants to fetotoksicheskoe the impact of the herbicide. Vegetative plants of sugar beet treated with an aqueous solution of 2,4,6-Tris[4'-carboxymethylamino(potassium)] -1,3,5-triazine (Curaxin-1). The aqueous solution has the following ratio of components: curaxin 10,001-0.002 wt.%, water the rest. The invention allows for the background fetotoksicheskoe action of roundup to increase the yield of sugar beet. table 1.

The invention relates to the field of agriculture, particularly to a method of increasing the resistance of vegetative plants of sugar beet to fetotoksicheskoe the impact of the herbicide.

The appearance on the world market of genetically modified sugar beet seeds, resistant to herbicide continuous action - ammonium salt of N-phosphonomethylglycine (roundup) - allows to obtain high yields of this crop without the cost of manual labor. However, such seeds are very expensive and effective ways of reducing roundpeg stress does not exist. This makes the problem of creating ways to reduce the toxic effects of roundup on sugar beet areactually.

23.gif">as a growth stimulator for presowing treatment of seeds of sugar beet, peas, wheat and rice [see U.S. Pat. RF 2083568; bull. inventions 1997, 19] . Application Curaxin-1 to reduce fetotoksicheskoe actions roundup is generally unknown.

It is also known the use of 1.2-dioxymethylene (DMK) formulaas a soil antidote protecting sunflower plants from fetotoksicheskoe action of 2,4-dichlorophenoxyacetic acid and its butyl ether (herbicide 2,4-D and EB 2,4-D) [see Chemical encyclopedic dictionary. - M. : Soviet encyclopedia. 1983, C. 550]. The disadvantages of using DMK are poor solubility in water and the necessity of preliminary bodrstvovaniya in alcohol, low efficiency, and the need for soil application.

On the application of DMK as compounds with antidote activity in relation to the total herbicide action N-phosphonomethylglycine (roundup) for growing sugar beet is generally unknown.

It is also known the use of nitroammophos as hipopotamo an antidote to the eradication of weeds in Apple orchards. Thus nitronates used in the form of an aqueous solution of 15% conzen, by pripochvennom making [see U.S. Pat. RF 2024230 /Apalkov F. F. / "Method to control weeds in young Apple orchards" on a 01 N 25/32].

The disadvantage of using such antidote is the acidic nature of this salt, the need pripochvennom making and using large (15 wt. %) of its concentration, which increases the expense and danger of chemical burns the leaves of growing plants.

Technical solution to the problem is to increase the sustainability of sugar beet to fetotoksicheskoe effects of the herbicide roundup.

The task is achieved by using 2,4,6-Tris[4'-carboxylate-phenylamine (potassium)] - 1,3,5-triazine (Curaxin-1), formulaas an effective antidote in the way of increasing the resistance of vegetative plants of sugar beet in the background of its herbicide oppression roundup.

The novelty of the claimed proposal is seen in the way of increasing the resistance of sugar beet to fetotoksicheskoe action of the herbicide roundup, featuring Curaxin-1 as an antidote vegetative plants of sugar beet in the form of an aqueous solution at a concentration of 0.001-0.02 wt. % that simultaneously allows to increase the productivity of roots without the method of the interaction of the aqueous-acetone solution of cyanuric chloride with an aqueous-alkaline solution of 4-aminobenzoic acid [see Pat. RF 2083568; bull. inventions 1997, 19] . Source cyanuric chloride immediately prior to use purify by crystallization from carbon tetrachloride.

In the proposed method Curaxin-1 is used as antidote to reduce fetotoksicheskoe action of the herbicide roundup on vegetative plants of sugar beet in field experiments. For comparison, using the aqueous dispersion DMK 1,2-di-oximetercucina in the form of an aqueous powder dispersion at a concentration of 0.002 wt.% and the consumption rate of 500 l/ha and an aqueous solution of nitroammophos concentrations of 15 and 0.002 wt.% (analogues).

When conducting small-plot field experiments used the seeds of sugar beet varieties Kuban MS-74". Seeds were sown in soil 15.05.01, wide-row method, the predecessor winter Kolosov, if the width of the row spacing of 70 cm and a seeding rate of 7 kg/ha Area of the experimental plots 2.8 m, the location of the plots randomizirovannoe, in quadruplicate. The balance of plant to stand density of 8 plants./m2conducted in phase 2 true leaves.

Thus prepared aqueous solutions Curaxin-1 concentration of 0.0001-0.03 wt. % handle pre-sprayed with an aqueous solution of roundup vegetating item not treated plants.

Example 1. In field experiments on the achievement of vegetating plants sugar beet phase 8-10 leaf plots with plants treated by spraying with an aqueous solution of roundup in the amount of 36 g/ha at the rate of solution flow rate 500 l/ha and concentration of roundup 0,0072 wt.%. After 1 day plots are sprayed with an aqueous solution Curaxin-1 at a concentration of 0.001 wt. per cent, at the rate of solution flow rate 500 l/ha On Mature conducted manual cleaning of the roots of sugar beet and weighing methods (accuracy5 g), the results of startanalysis define productivity in terms of kg/ha (see table). In medium samples of roots determine the content of sugars (sugar content, %) refractometric method for HOST-086. The decrease in plant productivity of sugar beet from roundpeg intoxication in the advanced options in comparison with control (UAvein % is determined by the formula YCR=(E/K)(100%, where K and e is the yield in the control and reference variants, respectively. Antidote effectiveness of drugs antidotes is determined by the formula ae=[(Y+a)-e]/e100%, where (Y+a) - yield option of applying the herbicide+antidote, e - productivity in atalo the x conditions conduct experiments 6, 9 and 10 with the use of the herbicide roundup, and as antidotes - DMK and nitroammophos (prototype), as well as experience 7 using to process only herbicide (standard) and control experience 8 - water treatment without the use of herbicide and antidote.

All experimental data were subjected to statistical analysis using t-student test at a probability of 0.95.

As can be seen from table (option 7), the application of the herbicide roundup at concentrations 0,0072 wt. % for treatment of vegetating plants sugar beet sharply (by 39.9%) reduces the yield (190 kg/ha instead of 312 kg/ha, respectively) and 0.5% sugar content. At the same time, the application of the proposed method against the background of the impact of roundup 2,4,6-Tris[4'-carboxymethylamino(potassium)] -1,3,5-triazine (Sebacina-1) as an antidote provides in comparison with the benchmark yield increase 5,26-15,78% (200-220 kg/ha instead of 190 kg/ha), while the use of known means DMK provides an increase of only 2,63%. It is also clear that the measure of the sugar content is not affected.

In the case of nitroammophos as antidote (examples 9 and 10) found that at a concentration of 15 wt.% because of chemical burns in sharky even when subsequent re-sprouting leaves. The yield of beet roots even in comparison with the depressed herbicide reference option however more than twice (see example 9). In the most active for the stated Sebacina concentration of 0.002 wt.%, nitroammophos antidote effect at all shows (see example 10).

Thus, the use of the claimed compounds as the antidote allows background fetotoksicheskoe of herbicide action to increase the yield relative to the benchmark without reducing sugar content.
