IMPROVING THE CHEMICAL METHOD OF CONTROLLING WEEDS ON SUNFLOWER
06.01.01 General agriculture, crop production (agricultural sciences)
DescriptionCurrently, there is no effective chemical protection of sunflower crops against dicotyledonous weeds during the growing season of the crop, except for systems that provide for the use of herbicides called Evro-Laiting, Zonator or Express. The disadvantage of these systems is the limited composition of cultivated sunflower hybrids and high costs. The article presents a research on the development of an effective system of chemical protection of sunflower crops against dicotyledonous and monocotyledonous weeds during the growing season of the crop. The greatest effect in the suppression of weeds in sunflower crops was observed by application of the herbicides Goal 2E and Senator on the germination of crop. In these versions of the experiment, the highest seed yield and oil harvest are also noted. However, the use of the Zonator is limited only to drug-resistant sunflower hybrids. The use of the herbicide Goal 2E is possible on any varieties and hybrids of sunflower. Despite the damage to the first two real sunflower leaves when using the herbicide Goal 2E for vegetation, the plants are fully restored, which does not significantly affect the productivity of the crop. The proposed schemes for using herbicides can improve the technological and economic efficiency of controlling monocotyledonous and dicotyledonous weeds in sunflower crops
