Roundly antidote for vegetative plants of sugar beet
The invention relates to agriculture, namely, to the means of protecting plants from fetotoksicheskoe of herbicides. As roundpeg antidote for vegetative plants of sugar beet accept 2,4,6-Tris[4'-carboxymethylamino(potassium)] -1,3,5-triazine(Curaxin-1). The invention allows for the background fetotoksicheskoe action of roundup to increase the yield of sugar beet roots without reducing its sugar content. table 1. The invention relates to the field of chemistry and agriculture, particularly to salts triazinetrione acids as compounds that protect against fetotoksicheskoe actions of herbicides in the cultivation of sugar beet (antidote).The appearance on the world market of genetically modified sugar beet seeds, resistant to herbicide continuous action of 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 drugs against roundpeg stress (antidotes) does not exist. This transforms the problem of creating roundpeg antidote in areactually.Known application of 2,4,6-Tris[4'-carboxyl growth 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 as a herbicide safener is generally unknown.It is also known the use of 1,2-dioxymethylene (DMK) formula:as 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% concentration for processing rows of Apple trees in the gardens for three weeks before treatment inter-row herbicide - Gyu 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 yield of sugar beet roots without reducing its sugar content on the background fetotoksicheskoe of herbicide action General action roundup.The task is achieved by using 2,4,6-Tris[4'-carboxymethylamino (potassium)]-1,3,5-triazine (Curaxin-1), the formula is:as an effective antidote suitable for processing vegetative plants of sugar beet in the form of an aqueous solution on the background of their herbicide oppression roundup.The novelty of the claimed proposal is seen in the use of Curaxin-1 as an antidote vegetative plants of sugar beet in the form of an aqueous solution at a concentration of 0.1 to 0.005 wt.%, to reduce fetotoksicheskoe the effect of the herbicide roundup and increase the yield of root crops without reducing sugar content in the background herbicide patania.Thus stated Curaxin-1 are well-known method by the interaction of the water-acetelene 1997, 19]. Source cyanuric chloride immediately prior to use purify by crystallization from carbon tetrachloride.The proposed 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 of the DMK - 1,2-dioxymethylene in the form of an aqueous powder dispersion at a concentration of 0.002 wt. % and the 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 precursor to 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 m2the location of 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 vegetative plants of sugar beet, as the decree is 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 After 1 day plots are sprayed with an aqueous solution Curaxin-1 at a concentration of 0.001 wt.% at the rate of solution flow rate 500 l/ha After ripening was performed 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 according to GOST 12571-086. 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: YAve=(E/K)100%, where K and e is the yield in the control and reference variant, respectively. Antidote effectiveness of drugs antidotes determined by the formula: Ae=[(Y+a)-e]/e100%, where (Y+a) - yield option of applying the herbicide+antidote, e is the yield in the benchmark (plants is avodat experiments 6, 9 and 10 with the use of the herbicide roundup and antidotes, and as antidotes used DMK nitroammophos (prototypes), as well as experience 7 using to process only herbicide (standard) and control experience 8 - 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 on the background of the impact of roundup offer 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 sugar svekla subsequent re-sprouting leaves. The yield of beet roots even in comparison with the depressed herbicide - reference option decreases more than twice (see example 9). In the most active for the stated Sebacina concentration of 0.002 wt. % nitroammophos antidote effect not prolapse (see example 10).Thus, the use of the claimed compounds as the antidote allows background fetotoksicheskoe of herbicide action to increase the yield of sugar beet roots relative to the benchmark without reducing its sugar content.
