Effect of Cylocate and Aldicarb Alone and in Combination on Growth of Three Sugarbeet Species(Betaspp.)

Abstract

Growth of sugarbeet(Beta vulgarisL. ‘Mono Hy A1’ and ‘Mono Hy D2′) and(B. patellarisMoq.) seedlings in cycloate(S-ethylN-ethylthiocyclohexanecarbamate)-amended soil infested with the sugarbeet nematode(Heterodera schachtiiSchmidt) was reduced (P = 0.05) at a concentration of 4 jug cycloate/g soil. Although the combination of cyloate with aldicarb [2-methyl-2-(methylthio) propionaldehyde-O-(methylcarbomyl) oxime] resulted in a significantly (P = 0.05) reduced growth of both sugarbeet cultivars andB. patellaris, it did not affect the nematicidal properties of aldicarb. Cycloate alone or in combination with aldicarb did not affect the growth ofB. procumbensChr. Sm. seedlings.
