Abstract
Abstract and SummaryFats, oils, and their derivatives are reviewed, in their roles as emulsifiers and surfactants and as pesticide derivatives, and in their activity per se. As emulsifiers and surfactants they offer a wide range of hydrophile‐lipophile balance (HLB) values to assist formulators in developing saleable products. Their lipoid solubilities aid in evaporation retardation, plant penetration, and absorption. Often they greatly improve the performance of the active ingredients. Nitrogen derivatives such as amines and quaternaries, fatty alcohols, acid esters, and other agricultural chemicals are reviewed. Examples are cited on the effect of the length of the carbon chain and their number in such herbicides as 2,4‐D and dalapon, as well as the biological properties of various aliphatic groups in insect larvicides, plant growth regulators, and fungicides. The role vegetable oils can play in the looming energy shortages as petroleum oil substitutes is discussed. They offer a challenging future in agricultural applications.
