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 ...

Spider-Mite Problems and Control in Taiwan
Experimental & Applied Acarology, 2000Problems with spider mites first appeared in Taiwan in 1958, eight years after the importation of synthetic pesticides, and the mites evolved into major pests on many crops during the 1980s. Of the 74 spider mite species recorded from Taiwan 10 are major pests, with Tetranychus kanzawai most important, followed by T.

Insecticide and Acaricide Tests, 1989
Abstract Azuki bean pesticide trials were conducted at the Warden Research Farm, Washington State University, Warden, Wash. Experimental plots were 0.01 acre each, arranged in a completely randomized design, and replicated 4 times. Plots were planted on 18 May at a density of 96,000 plants/acre.

Photoperiodic termination of diapause in spider mites
Nature, 1977TERMINATION of diapause in the spider mite Tetranychus urticae is considered to depend solely on a period of chilling, the so-called cold rest1–3. The minimal period of chilling required to reactivate a certain percentage of the overwintering population may vary between populations of different geographic origin4.

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 ...

Insecticide and Acaricide Tests, 1989
Abstract Test plots were established south of Twin Falls, Idaho. The soil type was Portneuf silt loam and the field was surface irrigated. Two tests were conducted using foliar sprays to control TSSM. In both tests the insecticides were sprayed with a CO2 pressurized backpack sprayer at 30 psi and hollow-cone nozzles to apply a broadcast
