Agricultural spray systems

It has been shown that the driftable portion of spray can be reduced by the addition of fully water-soluble high molecular weight linear polymers [47] and the performance in use has been stated to be reasonably correlated with extensional viscosity [48]. Non-ionic and low-charge density anionic polyacrylamide types are preferred as these products are generally compatible with pesticide formulations, particularly glyphosate formulations. The absolute efficiency provided by the polymer is dependent on other ingredients in the formulation as these materials can have an effect on the conformation of the polymer in solution. 

The very highest molecular weight polymers become increasingly difficult to dissolve in solid grade form when this is attempted directly in the tank mix prior to spraying. Products which are required for use in this way are therefore often supplied as inverse emulsions or LDPs in order to provide easier dissolution of the polymer.

The handling properties of the formulation in the field. Examples of handling properties are the amount of dust in the product (in the case of dry formulations), the manner in which the product dilutes with water (or other carrier liquid), the way in which the product sprays through an agricultural spraying system, and the manner in which the product will tank mix with other pesticide formulations. This paper is addressed to this last concern. 

Sludge Disposal. Land disposal of wet sludges can be accomplished ia a number of ways Lagooniag or the application of liquid sludge to land by tmck or spray system, or by pipeline to a remote agricultural or lagoon site.

This kind of study allows the determination (quantitatively) of the range of solubilization in any such application. These systems, when used to solubilize water-insoluble organic compounds, would require such information (in such systems as pharmaceutical, agriculture sprays, paints, etc.). The dosage of any substance is based on the amount of material per volume of a solution.

It is possible to breed plants that have more efficient systems for utilization of water, and agricultural technology can help existing crop plants by spraying impervious coatings on them. Extremely small amounts of long-chain, fatty alcohols reduce evaporation losses from quiet lakes or reservoirs to less than 5% of the normal surface evaporation. 

But stove oil, if not carefully used, left an oily flavor in carrots. Synthetic rubber reduced the need for guayule. Fuel oil prices had advanced to a level that almost prohibited their use for weed control. The future of oil in the herbicide field was in doubt. Yet farmers needed oil sprays for their irrigation systems, which were infesting their fields with weeds, and for their fence lines, which were harboring thrips and other insects and diseases. These problems of research were undertaken by the agricultural experiment stations in California, Massachusetts, New York, and other states.
