Abstract
The effect of various levels of pendimethalin (Herbadox 330E) on different growth stages and development of "aguingay" (Rottboellia exaltreta L. f.) and corn (Zea mays L.) was determined. Rottboellia exaltata at seed and coleoptile stages was observed to be highly susceptible to all levels of pendimethalin, However, in corn, pendimethalin at 0.75 to 3.0 kg/ha rates sprayed during the coleptile stage caused root stunting, swelling of the root tip and abnormal fruit development. St further growth stage or during 2 to 3 leaf stage, herbicide treatments only provided 60 to 90% control of the weed and showed no visible effect on corn. Beyond this period, both the weed and the crop were already safe to pendimethalin.
