showed significant yield increases on cucumber with metham sodiurn applied one month before planting;
and on tomato with metham potassium applied one month before planting or fenamiphos 240 CS applied one
day before planting. In both trials, yields were f~irtherin creased by applications of either the granular or the microcapsulatecl
