Abstract
See also WA 23, 287. The main environmental factor causing variation in the emergence of Striga appears to be soil m.c.; saturated seeds go into a state of wet dormancy and are incapable of germination until dried. S. hermontheca infestation on sorghum at Samaru does not normally develop until the end of the rainfall peak. In the abnormal season of 1971, an infestation developed before the heavy rain started but the emerged plants died naturally during the rains. Soil applied herbicides should be applied just before the end of the rains. The best residual herbicide tested was dinoterb formulated as a 6% urea granule applied at 1.1 kg a.i./ha 3 times (in mid-August, mid-September and mid-October). In environments where the crop grows to maturity without being subjected to rainfall heavy enough to kill emerged Striga plants, the best time for treatment will probably be soon after sowing. Where heavy rainfall does normally occur during crop growth, the herbicide should be applied shortly before the end of the rains
