- Abstract
SUMMARY Incorporated in silt or peat loam top-soil in spring before susceptible potatoes were planted, three carbamoyl oximes, aldicarb, Tirpate (2,4-dimethyl-2-formyl 1-1,3-dithiolane oxime iV-methylcarbamate) and Du Pont 1410 ( S-methyl i-(dimethylcarbamoyl)- N-((methylcarbamoyl) oxy) thioformimidate) and one organophosphate, Nemacur ( O-ethyl- O-(3-methyl-4-methylthiophenyl)-isopropylamidophosphate) all at n-2 kg a.i./ha greatly increased the yield of tubers and effectively controlled potato cyst-nematode (Heterodera rostochiensis Woll.). At the same dosage thionazin was as effective in the peat loam but was ineffective in the silt loam; phorate and Mocap (O-ethyl S,S-dipropyl phosphorodithioate) were less effective and chlorfenvinphos, diazinon and a coarse granule formulation of fensulphothion were ineffective in controlling potato cyst-nematode.
