An agricultural implement has a product supply chamber, and a pair of transversely extending product delivering booms, each with a plurality of conduits of varying lengths terminating in product distributing nozzles. A fan supplies air to a mixing chamber which also receives product from the supply chamber providing an air entrained flow of product to each conduit. A controller monitors product delivery and controls implement operation. Each conduit has a pressure tap near the nozzle for providing the controller with a pressure differential indication. The controller initiates a corrective action modifying the operation of the delivery system when a predetermined pressure differential threshold is exceeded. The corrective action may include an increased air flow volume, an additional burst of higher pressure air into the conduit, a temporary increase in air flow from the air flow source, or a reduction in the rate of product flow from the supply chamber.

A spray head for an agricultural sprayer, the spray head including a fan with a central axis, the spray head also including dual liquid manifolds coaxial about the fan's central axis, each manifold having a plurality of spray nozzles positioned to be capable of spraying liquid into air exiting the fan, and each manifold having a liquid inlet and a liquid outlet so as to permit individual control of liquid through each manifold.

The present invention provide chemical modulators of insect olfactory receptors. In particular, compounds and compositions are provided that can inhibit host targeting functions in insects such as mosquitos. Method of employing such agents, and articles incorporating the same, are also provided.

Meshes capable of droplet fragmentation are generally described. Inventive articles, systems, and uses thereof are also described.

A system and adjustable apparatus for applying CO.sub.2 gas to improve Cannabis production. The system includes upstream and downstream stages or subsystems. The upstream subsystem receives and stores gas, particularly CO2 gas. It monitors the environment of the downstream subsystem, determines when and how to apply gas to plants growing in the downstream system, acquires gas stored in the upstream subsystem, and distributes it to the downstream system. It also has various monitoring, command and control, management, and reporting features. The downstream subsystem includes one or more plant growth areas or plots, gas distribution means, such as gas conduits, tubes or lines from the midstream subsystem, and the high efficiency, adjustable gas applicator, and various sensing and monitoring devices communicatively connected to the upstream subsystem. Also disclosed are systems, apparatus and methods for pest control, humidity control, and odor control.

A dispensing system includes a substrate made of a porous material that defines a channel. The system also includes a base in contact with the substrate, A container for discharging a flowable medium into the channel is completely accommodated within the base and is partially exterior to the substrate.

A device for dispersing in the air in the vapor state and a substance that is in the liquid state at ambient temperature, and is contained in a storage container, has a ventilation system with a duct that opens out into the open air and is configured to permit the passage of a flow of air into the duct; at least one dispensing unit is designed to be supplied with a liquid substance by the storage container, the dispensing unit having micro-ducts forming an outlet is provided in the duct in order to constitute an area of evaporation of the substance therein, and a heating unit is provided on or in the dispensing unit, such as to control a flow of the substance through the dispensing unit.

The present invention provides a new insect pest control agent that can instantly stop the movement of an insect pest and kill the insect pest, but that does not have a risk of explosion or ignition and that does not destroy the ozone layer and that has a low global warming potential, and therefore that can be safely used. An insect pest control agent comprising 1-chloro-3,3,3-trifluoropropene as an active agent solves the above problem.

The present disclosure relates to arthropod pest control sprays and methods of using such sprays to control arthropod pests.

The invention relates to a new atomizing device with improved droplet formation. Smaller droplets are formed with increased micronized volume throughput, wherein high volumes of air are fed to a liquid sprayed from a liquid nozzle. High volume ratios result in mean free path between droplets being conveyed so as to minimize collisions and to prevent aggregation of the droplet.
