Pesticide application device for preventing and controlling underground plant diseases and pests of tobacco

Abstract

The invention discloses a pesticide application device for preventing and controlling underground plant diseases and pests of tobacco. The device comprises a vehicle-mounted platform and an angle adjusting column arranged on the vehicle-mounted platform, wherein at least one side of the angle adjusting column is provided with soil digging and pesticide applying arms. The device is characterized inthat each soil digging and pesticide applying arm includes an arm body, a sliding rod, a bracket and a ring knife, wherein the sliding rod, the bracket and the ring knife are sequentially connected in the length direction of the arm body; a soil pouring plug is arranged in each bracket and sleeved with the corresponding ring knife to form a piston structure with the ring knife; the end part of each ring knife is parallel to the free end of a pesticide application pipe on the corresponding soil digging and pesticide applying arm, and the ring knifes and the soil pouring plugs can separately and independently move. The pesticide application device for preventing and controlling the underground plant diseases and pests of the tobacco has the advantages that the pesticide application is uniform, targeted slow-release capsules for prevention and control are directly applied near the root systems of plants, the underground plant diseases and pests are precisely prevented and controlled, andthe usage amount of the biological pesticide is reduced.

Description

technical field [0001] The invention relates to the field of tobacco pest control, in particular to a pesticide application device for tobacco underground pest control. Background technique [0002] Nowadays, environmental issues and food safety issues are attracting more and more attention, and the green prevention and control of agriculture has attracted much attention. However, the prevention and control methods of underground pests and diseases generally have the problems of large dosage and high application cost, resulting in limited application in the market. At present, there are already some biopesticide products that have good control effects on underground diseases and insect pests, including Metarhizium anisopliae, Beauveria bassiana, Bacillus, entomopathogenic nematodes, etc. It has been reported in some foreign literatures that carbon dioxide has a general attractant effect on many underground pests and plant pathogenic nematodes, and is usually the target for t...
