Abstract

A method for controlling ragweed under conditions of a mixed type of weediness of soybean crops includes the use of herbicidal compositions combining acetolactate synthase inhibitors and acetyl Co carboxylase inhibitors. A ratio of components is 0.8-1.0:3.0-1.0.

Description

mixed type of weediness would have a wide cid, 30 days after spraying crops and spectrum of action, had high selectivity to plants before harvesting. Harvest accounting was carried out and the emergence of resistant fields was made possible by the "SAMPO" harvester in the phase of full ripening of ragweed pollination. grains Crops had a mixed type of weeds

The goal is achieved by the use of herbicidal ones, where annuals predominated among grasses (mouse compositions, where individual components have a risis), and dicotyledons were mainly represented by this mechanism of action. Thus, imazetapir, which is an inhibitor of polyno-leaf ragweed, white quinoa, and acetolactate synthase, is combined with fluazizia ordinary, wild radish, and mustard with rolofop-P-butyl, which is an inhibitor of acetyl Sohyme. The results of the research are given in Table 1 of carboxylase. A significant expansion of the spectrum of action, as evidenced by the fact that the herbicidal activity of bentazone against ragweed, as well as other types of butyfensulfuron-methyl and their mixture was low, is provided by the combination of thifensulka. The level of total weediness was reduced by furon-methyl, which is an inhibitor of acetolactate- by 40-4195, but ragweed plants were killed by synthase with hyzalofop-P-ethyl, which is an inhibitor by 84-86 95 compared to the control. Among the types of bur'-acetyl Co carboxylase. The method differs in that those that remained stable turned out to be: mouse with a ratio of components of 0.8-gray, chicken millet and white quinoa, which reached 1.0:3.0-1.0, and their consumption rates are reduced by 20- height 6-8 cm. As a result of insufficient reduction of 3895 without reducing their biological effectiveness. the level of weediness, a significant increase in yield-

Due to the different mechanisms of action of individual components in these options, the quality of the seeds is not obtained, and the phenomenon of synergism occurs, which causes the subsowing to not increase compared to the weedy increase in herbicidal activity and makes it possible to control (Table 2). emergence of the phenomenon of resistance. Herbicides are used. The use of imazethapyr (0.1 ml/ha) in the clean bottom of the composition after the appearance of soybean seedlings in phase 1-3 of its form ensured the destruction of weeds of all leaves. virgins on 8395, including the death of ambrosia poly-

For the study of the harmfulness of ragweed, it was at the level of 8695. Taking into account the fast-leaved and other weeds and the biological effectiveness of the appearance of resistant populations of ragweed and the proposed compositions in the laboratory, the negative effect of imazetapyr on other crops by the Institute of Fodder and Plant Protection of the Ukrainian Academy of Sciences of the maximum rates of its consumption (0.8-1.Ol/ha) during 2006-2008. carried out field studies revealed the need to use it in gin mixtures. The area of the sown plot is 38m", accounting for 30-3895 at the reduced rates. Therefore, the introduction of 25m2, the repetition is four times. The placement of imazethapyr (0.5l/ha) caused the death of buds was randomized. The tank mixtures were prepared before the yans of all types at 8395 , and ragweed plants were destroyed by spraying. The introduction was carried out with a knapsack at 8695. At the same time, the yield of seeds by a sprayer in the phase of 1-3 leaves of soybeans. The rate increased by 0.57t/ha compared to weeding. The consumption of working fluid was 25O0l/ha Quantitative and specific control (Table 2).
