The invention relates to agriculture, namely to chemical herbicides for controlling undesirable vegetation in crops of cereals and industrial areas.
A known method for killing weeds in industrial areas, including the application of soil working fluid containing the herbicide "Anchor 85", made on the basis of sulfometuron, and adding 3-15% antifreeze, while its application produced in the period from the end of the growing season to establish a permanent snow cover (RF patent No. 2280125, publ. 20.07.2006). The destruction of weeds is the closest technical solution to the proposed method of destruction of weeds.
The disadvantage of this method of destruction of weeds is the need for repeated tillage due to receive a weak solution of the working fluid.
The technical result, which aims the proposed method for the destruction of weeds, is to increase the efficiency of destruction of weeds while reducing the number of soil by increasing herbicide activity of the composition of 15-20%, the acceleration time of the manifestation fetotoksicheskoe action herbicide composition on plants and increase level the activity of the herbicide composition to 15-22% against grass weeds and shrubbery.
This technical result is ensured by the fact that in the method for killing weeds comprising applying the fluid containing the herbicide composition, weed vegetation, according to the invention the working fluid contains a herbicide composition, which is added 0.2% monoperoxyphthalate urea at the rate of 20-40 grams of monoperoxyphthalate urea per 1 hectare, while drawing on weed vegetation carried out once during the whole vegetation period.
Table 1 shows the number of downloads and physico-chemical properties of tank mixtures of herbicides and monoperoxyphthalate urea; table 2 presents data on the biological effectiveness of herbicide tank mixtures of the drug, water-dispersible granules (EDC 750 g/kg) and monoperoxyphthalate urea, table 3 shows data on the effectiveness of herbicides on railroad tracks within 120 days after the application (Moscow region wildebeest vniif, 2006)
The method of destroying vegetation confirmed by the following examples:
In capacity for the preparation of the working solution is poured 70 l of water, then back at stirring paid 64 g of the herbicide in the form of water-dispersible granules and 0.32 g of monoperoxyphthalate urea and added 130 liters of water and the resulting suspension processing is to see the weeds.
In capacity for the preparation of the working solution is poured 70 l of water, then back in the quantities listed in table 1 with stirring paid herbicide composition (in the form of water-dispersible granules), monoperoxyphthalate urea and top up with water.
Prepared according to examples 1 and 2 working solution was treated with weeds and assessed the biological efficacy on reduction of impurity sites.
In the field of the Moscow region wildebeest vniif in 2006 were tested herbicide product (water-dispersible granules EDC 750 g/kg) - the standard and its tank mixture with monoperoxyphthalic urea on railroad tracks.
Data on efficacy are presented in table 3.
The proposed method for the destruction of weeds provides 15-20% gain herbicide activity sulfometuron, 1.5-2 times faster developing time fetotoksicheskoe action of the herbicide on weed plants, increased by 15-22% of the level of activity against grass weeds and shrubbery.
The list of objects of non-agricultural areas that use this method of destroying weeds: cross - country oil and gas pipelines, embankments and right-of-way railroads and highways airports, control and tracking belts and other industrial areas.
Implementation of the proposed method using a water-dispersible granule herbicide preparation with the addition of monoperoxyphthalate urea 20-40 g/ha compared to water-dispersible granules known herbicide composition allows to enhance herbicide activity, 1.5-2 times faster the acceleration time of the manifestation fetotoksicheskoe action herbicide composition on plants.
