Abstract:

Of 25 insecticides sprayed onto cattle for control of Boophilus annulatus (Say), the cattle tick, or B. microplus (Canestrini), the southern cattle tick, the following afforded > 99% control of either or both species: 0.1% Allied Chemical ACD-10284 (O,O diethyl phosphorodithioate S-ester with N- (2-cyanoethyl) -2-mercaptoacetanilide); 0.05% Bay 64995 (O,O-dimethyl phosphorothioate O,O-diester with 4,4-dithiodiphenol); 0.1% bromophosethyl; 0.025% chlorpyrifos; 0.125% Ciba C-9491 (0- (2.5- dichloro-4-iodophenyl) O,O-dimethyl phosphorothioate); 0.075% crotoxyphos; 0.025% diazinon; 0.05% dioxathion; 0.05% fenthion; 0.03% ImidanĀ® (O,O-dimethyl phosphorodithioate S-ester with N- (mercaptomethyl) phthalimide) ; 0.005% isobenzan; 0.5% malathion; 0.1% monocrotophos; 0.5% ronnel; 0.25% Shell SD-8447 (2-chloro-l- (2,4,5-tri-chlorophenyl) vinyl dimethyl phosphate); 0.1% Shell SD-8949 (1- (2-bromo-4,5-dichlorophenyl) -2-chlorovinyl dimethyl phosphate); 0.1% Shell SD-8988 (2-bromo-l- (2,4-dichlorophenyl) vinyl dimethyl phosphate); 0.5% toxaphene; and 0.5% trichlorfon. A solubilized formulation (I part technical material:2 parts TritonĀ® X-100) was as effective as an emulsifiable concentrate of Compound 4072 (2-chloro-l- (2,4-dichlorophenyl) vinyl diethyl phosphate) . Fresh and aged (21 weeks) dips of 0.073-0.164% dioxathion and fresh and aged (51 weeks) dips of 0.010-0.049% chlorpyrifos also afforded > 99% control. In addition, a dip of 0.05-0.25% Shell SD-8447 was highly effective, but the chemical analysis of the dip fluids was unsatisfactory.
