AN ECONOMIC ANALYSIS OF TELONE II (1, 3-D) AND TEMIK 15G (ALDICARB) TO MANAGE RENIFORM NEMATODE (ROTYLENCHULUS RENIFORMIS) IN COTTON

摘要

The abilities of aldicarb (Temik 15G) and 1, 3-D(Telone II) to control reniform nematodes (Rotylenchulus reniformis) were tested over three growing seasons, 1995, 1997, and 1998. Phorate (Thimet 15G) was applied at a rate of 6.7 pounds per acre in conjunction Telone II in order to control thrips. Four rates of each of the primary chemicals was applied each year and a treatment of Thimet only was the control or check. In 1997 and 1998 a combined Temil 15G-Telone II treatment was included. That treatment did not include Thimet 15G. A randomized block design was used in all years. Net returns based upon dollar 0.60 and dollar 0.70 per pound of lint were estimated for each of the treatments in terms of yield and net returns. The responses of the other treatments were some what erratic. Generally with prices at dollar 0.70, the Telone II treatments had greater net returns than the Temik treatments. The net returns for dollar 0.60 were not as consistent.
