Insecticide and Acaricide Tests, 1989
Abstract Acaricides were applied to cotton planted 31 Mar in individual plots 8 (40 inch) rows wide by 150 ft long and replicated 4 times in a randomized complete block design. Application was by high-clearance ground sprayer equipped with drop booms using 3 or 5 hollow-cone TX-6 nozzles/row, depending on plant size, delivering 15 or 25 ...

Nature, 1945
SINCE the discovery in 1936 of its insecticidal properties, 2:4 dinitro-6-cyclohexylphenol1 has been widely used in the United States for the control of tetranychid mites. Successful control has been obtained of Paratetranychus citri (McG.)2,3 and of Tetranychus telarius (L.) on citrus, cotton4 and hops5; on all these crops damage by red spider is of ...
