7 results about "Spray drift" patented technology

The present application relates to the technical field of pesticide application, and particularly relates to a pesticide spraying drift prevention method, obtaining plant image information to be identified, identifying the plant to be identified according to the plant image information to be identified, obtaining a three-dimensional model of a plant to be sprayed if the identification result is a first identification result, segmenting the three-dimensional model of the plant to be sprayed into a plurality of sub-spraying areas, obtaining a preset spraying path according to characteristic parameters, spraying starting point information and the three-dimensional model of the plant to be sprayed, obtaining real-time spraying environment parameters at each spraying time node, determining a real-time spraying drift amount according to the real-time spraying environment parameters, and correcting and adjusting the preset spraying path according to the real-time spraying drift amount. The method can improve the deposition of pesticides in a target area, reduce pollution to non-target areas, protect the ecological environment, improve the use effect of pesticides and reduce resource waste.

The present invention pertains to the agricultural field, and particularly to the use of tall oil fatty acids as a phytosanitary adjuvant, particularly for preventing spray drift. The present inventors have indeed shown that the introduction of tall oil fatty acids into phytosanitary compositions allows increasing droplet size distribution upon spraying and therefore reducing off-target spraying. The present invention therefore provides methods for generating droplets, treating plants and for preventing spray drift. The invention also relates to phytosanitary compositions comprising tall oil fatty acids.

This invention provides a spray drift monitoring and control system for pesticide sprayers and its usage method. The system is installed on the pesticide sprayer and includes: an information acquisition module for collecting environmental and droplet information; a central control system for receiving the environmental and droplet information in real time and controlling the opening and closing of a solenoid valve after analyzing the information; and an actuator for spraying according to the opening and closing of the solenoid valve. This invention is applicable to plant protection operations in agricultural work, reducing pesticide drift and production costs, while also protecting crops from damage caused by excessive pesticide application.

The present invention is a multiplexed inertial coalescence filter system that minimizes spray drift and maximizes droplet transfer efficiency to improve the precision and safety of industrial spray applications. In an alternate embodiment, a hollow multiplexed inertial coalescence filter is rotated around its longitudinal axis to capture droplets or particles from a fluid stream flowing therethrough.

Spray drift reducing agents for agrochemical formulations for spray drift reduction in agrochemical formulations containing active agents and / or micronutrients. The reducing agent is selected from an alkoxylated polyol or polyamine, which is optionally acyl-terminated, and the formulation may optionally comprise a nonionic alkoxylate. Also provided are methods of making the formulations, and the use of the formulations to reduce spray drift in the case of applying agrochemical formulations to plants.

The disclosure relates to agricultural spray compositions that reduce spray drift using a drift control adjuvant comprising decarboxylated rosin acid (DCR), a surfactant system, and optional components, in combination with an agricultural chemical component in a carrier. The drift control agent may be supplied as neat DCR or as part of the adjuvant. Methods include preparing the spray by (i) combining the adjuvant with a concentrated agricultural chemical component to form a concentrate composition and diluting with a carrier, or (ii) diluting the agricultural chemical component with a carrier and subsequently adding the adjuvant. When discharged through spray nozzles, the compositions increase droplet size and narrow the droplet-size distribution, thereby reducing fine droplets and spray drift while maintaining coverage and compatibility across a range of agricultural actives.
