Note to readers, attached is the complete final report for FNE94-075.
The recommended application rate for an Atrazine-Dual tank mix for 1996 is 1.233 lb of Atrazine and 1.60 lb of metolachlor per acre. Our results demonstrate that these levels can be reduced to at least 41% and 62.5% respectively, of these amounts with minimal loss of weed control. By using only 0.5 lb of altrazine and 1.0 lb of metolachlor per acre, a farmer can save $7.89 per acre in chemical expenses and still achieve an acceptable degree of weed control. Problems caused by atrazine carryover are negated. In our best case only .3 lb/acre of atrazine was used in acceptable levels of control.
