摘要： An agricultural sprayer assembly includes a wheeled carriage, a chassis, and a spray delivery system. The wheeled carriage has a number of adjustable support legs (e.g., four), each formed of hydraulically coupled and actuated upper and lower leg sections or members. The chassis is supported on the wheeled carriage, at an adjustable clearance height defined by the operational height of the support legs. The spray delivery system includes a spray boom coupled to a boom support, and an actuator coupled to the boom support and the chassis. The actuator is configured to adjust the height of the spray boom with respect to the clearance height of the chassis.

摘要： 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.

摘要： 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.

摘要： Plant growth compositions include a mixture of inert compounds and an active component combination of auxin, gibberellin and cytokinin. The plant growth compositions are auxin-dominant, and the ratio of cytokinin to auxin in the active component combination ranges from about 1:10.5 to about 1:4.5. The amount of cytokinin ranges from about 0.1 to 10 wt % by weight of the active component combination in plant growth compositions formulated for in-furrow application to corn plants. Methods of improving plant growth involve in-furrow, seed and/or foliar application of one or more plant types with a plant growth composition. Improvements in plant growth include increases in the average number of bushels produced per acre.

摘要： Hydrogels are blended with water to produce a hydrogel solution. Viscosity of the hydrogel solution is controlled by adjusting the ratio of hydrogel to water and/or by adjusting the blending conditions. The hydrogel solutions may be used to modify the rheology of agricultural compositions. The hydrogel may include lactose, which may be provided by a milk permeate waste stream from the dairy or food processing industry.

摘要： Methods of extracting ribonucleic acid from plant tissue involve treating multiple groups of plant seeds with different plant growth regulators. Each group of plant seeds can be treated with a different plant growth regulator. Methods further involve germinating the plant seeds to form seedlings, harvesting tissue samples from subgroups within each group of plant seeds and seedlings at different timepoints, and extracting total RNA from each harvested tissue sample. Methods can also involve sequencing the extracted RNA, determining an expression level of a plurality of genes relative to a negative control, and identifying a subset of differentially expressed genes at each distinct timepoint.

摘要： A wind tunnel device may include a waste disposal unit configured to collect fluid from a droplet extractor positioned in a wind tunnel. The waste disposal unit may include a drain line and a liquid trap integrated in the drain line. The liquid trap may be adjustable during operation of the wind tunnel to accommodate different tunnel operating conditions (e.g., wind speeds) such that liquid waste does not backflow into the wind tunnel.

摘要： 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 μm, about 150 μm, and/or about 210 μm compared to an agricultural spray neither or only one of the oil emulsion drift reduction adjuvant and the spontaneous emulsion drift reduction adjuvant.
