Use of cadusafos and terbufos against larvae of Antitrogus parvulus and Antitrogus consanguineus (Coleoptera: Scarabaeidae) in sugarcane in southern Queensland
1997
Allsopp, P.G. | McGill, N.G.
Cadusafos granules (Rugby 100G) provided control of larvae of Childers canegrub, Antitrogus parvulus Britton, and southern 1-year canegrub. A consanguinensis (Blackburn), in infested ratoon crops of sugarcane in southern Queensland. Providing larval numbers are above a damaging level, such control resulted in increased yields of sugarcane. Rates as low as 20 kg product/ha (3 g product per row m) were effective. Cadusafos was at least as effective as ethoprophos (Mocap 10G) at 25 kg product/ha and, at these rates, both cost about the same. Control of larvae of A. parvulus with terbufos (Counter 150G) was inconsistent between two trials and in neither trial did application result in yield increases.
