Purpose of the development: Improving the efficiency of weed control in growing winter crops.

Recommended application field: Agriculture (crop).

The development stage readiness: Introduced in production

Technical and economic effect: Implementation of development on private-rental company "agrarian" that Volodarskiy district of Kiev region., On an area of 500 hectares has reduced the costs of herbicides by 15-35%, while the destroyed up to 90% of weeds. Calculations show that for the same cost of herbicides in making their return in the fall of this event in the 1.2-2.8 times higher than in the spring. If necessary, to carry out a further reduction in contamination can be applying herbicides in the spring.

Description of the development:
()
Monitoring the production of crops shows that 75% of winter crops weed cenosis formed during the autumn period due to winter, and two monocotyledonous species. Among the most common bipartite trirebernik odorless, shepherd's purse plain, field violet, cornflower blue, cleavers, yarutka field, which make up about 60% of the core cenosis. With winter cereal common metlyug usual, annual bluegrass, particularly in the south of the forest-steppe and steppe zones - bromus rye. Number of weeds depends on how the main tillage precursors, soil type, terrain. It is advisable to monitor the amount of weeds in the fall, during the growing season of winter. Application of herbicides to the specified time has become possible with the advent on the market of products manufactured on the basis of sulfonylureas which exhibit herbicidal effects at a temperature ranging from +5 ° C, which makes it possible to destroy weeds in a state of germination. As the results of studies that formed the basis for the development of the properties of this group of herbicides significantly better manifested in the autumn. So, less than the recommended dose of herbicide introduced in the autumn, as well as or even better effect on weeds than large doses that are made in the spring, due to the greater sensitivity and less resistant weeds to drugs.
