Granulated soil insecticidal-nematicidal compositions with reduced mammalian dermal toxicity

A method for protecting crops from attack by insects and nematodes while inhibiting the growth of undesirable plant species in the presence of said crops which comprises applying to soil in the locus of said crops, at or about the time of planting, an insecticidally-nematicidally effective amount of a cellulosic, granular composition at least 90% of which is -8, +48 mesh granules having a bulk density of from 20 lbs/cft to 45 lbs/cft and a pH value between pH6 and pH8 and absorbed therein from 2% to 20% by weight of terbufos and thereafter applying to the locus of the said terbufos treated crops approximately 2 to 4 weeks after planting and after said crops have emerged, a herbicidally effective amount of an acetohydroxyacid synthase (AHAS) inhibiting herbicide,. said method reducing or eliminating crop injury due to interaction between terbufos and the AHAS inhibiting herbicide.
