Abstract
The agroclimatic resources of the Astrakhan region are quite large and represent huge opportunities in the production of heat-loving crops such as vegetables and melons. The region has accumulated a great scientific and production experience in the cultivation of tomatoes as the main vegetable crop rotation crop.To date, the first task for farmers of the region is to develop new modern agrotechnological techniques to eliminate the spread of thrips on open-ground tomato plants. The object of research was a hybrid of tomato of the domestic selection of the agricultural company Sedek Azhur F1. Materials and methods.For the first time, for the conditions of light chestnut soils on the land use territory of FSBNU “Caspian Agrarian Scientific Federal Scientific Center of the Russian Academy of Sciences” during 20182020. the influence of various insecticides in the fight against tripasmi was studied.As a result of the analysis, the presented scientific article presents the main results for the study of new modern insecticides in the fight against trypses on open-ground tomato Azhur F1. According to the results of three years of study, the optimal option with the use of the drug Confidor Extra was revealed, which contributes to a significant decrease in the number of phytophages.The use of these preparations had no phytotoxic effect on open-ground tomato plants. In the version using the insecticide Confidor Extra, there was more purely commercial fruits and a significant increase in the crop relative to control without treatments, as well as a variant where the Fufanon-Nova preparation was used. The increase relative to control in the high-yield version was + 40.8 t/ha or 43.5%.
Highlights
Trips is the most serious pest of vegetable crops [4,5,6,7; 916]
Crop damage depends on many factors: the size of the thrips, the size of its population, the phase of plant development for the period of plant damage, the duration of the period of damage
One of the promising areas for the development of a system of protective measures in the fight against trips is the use of new insecticides in modern agricultural technologies
Summary
Trips is the most serious pest of vegetable crops [4,5,6,7; 916]. Crop damage depends on many factors: the size of the thrips, the size of its population, the phase of plant development for the period of plant damage, the duration of the period of damage. About 7,700 species of thrips have been recorded [8]. Trypses have piercing and sucking types of oral parts. As a result, they damage crops either during the absorption of food or by huge ovipositors. One of the promising areas for the development of a system of protective measures in the fight against trips is the use of new insecticides in modern agricultural technologies
