Abstract: Reducing fines from an agricultural spray dispensed from a nozzle is provided in the disclosed methods. The agricultural spray comprises water, an agricultural composition such as a pesticide, at least one oil emulsion drift reduction adjuvant, and at least one spontaneous emulsion drift reduction adjuvant. The agricultural spray exhibits fewer fine droplets having a diameter less than about 105 ?m, about 150 ?m, and/or about 210 ?m compared to an agricultural spray neither or only one of the oil emulsion drift reduction adjuvant and the spontaneous emulsion drift reduction adjuvant.

Abstract: A wind tunnel device defines a cyclical tunnel to receive continuous airflow. Airflow is delivered through the tunnel to a testing region that includes a first portion carrying an arm including a spray tip configured to spray particulates in the testing region at an angle, and a second portion including an enlarged cutout region configured to receive the angled sprayed particulates. As airflow carries the angled spray particulates into the second portion, the enlarged cutout region enables the spray particulates to pass through and exit the second portion of the testing region. Analysis in the second region may be conducted through transparent walls free of openings to minimize exposure of the spray particulates to the exterior of the device. A scrubber is adapted to extract spray mist from the airflow as the airflow exits the testing region and is re-circulated through the cyclical tunnel.

Abstract: The application is generally directed towards an airfoil for a fluid delivery tube. The airfoil includes a securing member operably connecting the airfoil to the tube, a fin extending downward and outward from the securing member and terminating in a tip, a shield extending inward and downward from the tip of the fin, and an air guide extending from a first end of the shield.

Abstract: Computer-implemented systems and methods predict behavior of sprays based on receiving a selection of one or more variables affecting spray. Relative amounts of the droplets forming the spray are grouped into various droplet size classes, where each droplet size class represents a range of droplet sizes. The relative amounts of the spray in the classes is visually depicted on a computer display according to a distribution of droplets, a volume of spray falling within the droplet size classes, a chart depicting relative amounts of the spray as a function of droplet size, or according to a spray quality based on environmental factors.

Abstract: Disclosed herein are methods of applying agricultural compositions including a pesticide, a fertilizer, or a combination of two or more of these, and about 0.1% v/v to 1.0% v/v of an adjuvant composition. The methods provide for aerial application of the agricultural compositions at wind speeds of up to 170 mph without substantially increasing the number of driftable droplets dispensed compared to the number of driftable droplets dispensed by applying the agricultural compositions without the adjuvant.

Abstract: The application is generally directed towards a drop nozzle for an agricultural sprayer. The drop nozzle can be used to reduce spray drift as liquids are deposited by the sprayer. The drop nozzle includes a valve assembly including a shutoff valve, a tube operably connected to the valve assembly, and an airfoil connected to the tube. The shutoff valve selectively prevents fluid flow from the valve assembly to the tube and the airfoil directs airflow around one or more portions of the drop nozzle.
