Sweetpotato [Ipomoea batatas (L.) Lam.] Response to S-Metolachlor and Rainfall under Three Temperature Regimes

The S-metolachlor is used to control/suppress yellow nutsedge, annual grasses, and several broadleaf weeds in sweetpotato. However, when used under adverse environmental conditions, it may lead to crop injury. Information is limited on the effect of S-metolachlor application followed immediately by rainfall on sweetpotato growth and development under different temperature regimes. The objective of …
