Organic Chemicals in the Environment Effect of Starch Encapsulation and Temperature on Volatilization of Atrazine and Alachlor
Volatilization of agricultural chemicals is one process whereby chemicals may enter into parts of the environment where they were not intended. Starch encapsulation of pesticides has been proposed as a way of modifying pesticide behavior in the soil environment. This study was conducted to assess how starch encapsulation and temperature affect volatilization of atrazine [6.chloro-N-ethyI-N’-(l-...

متن کامل(1992) Effect of Water Potential, Temperature, and Soil Microbial Activity on Release of Starch-Encapsulated Atrazine and Alachlor
Starch encapsulation has been proposed as a method for controlling the rate at which pesticides are released into the soil. Relatively ittle is known about what environmental f ctors influence controlled release. A series of laboratory studies were initiated to improve our understanding of how water potential, temperature, and soil microbial activity influence rate of release of starch-encapsul...
متن کاملEffect of Formulation and Tillage Practice on Volatilization of Atrazine and Alachlor
Conservation tillage practices are being implemented by many farmers to conserve water and soil resources. These practices may modify the soil surface in ways that differentially effect dissipation of pesticide when compared to conventionally tilled fields. We measured volatilization of atrazine [2-chloro-4-ethylamino-6-isopropylamino-s-triazine] and alachlor [2-chloro-2'-6'-diethyl-n-(methoxym...
متن کاملHerbicide leaching as affected by macropore flow and within-storm rainfall intensity variation: a RZWQM simulation.
Within-event variability in rainfall intensity may affect pesticide leaching rates in soil, but most laboratory studies of pesticide leaching use a rainfall simulator operating at constant rainfall intensity, or cover the soil with ponded water. This is especially true in experiments where macropores are present--macroporous soils present experimental complexities enough without the added compl...
