Option 2: 5% Unsprayed Refuge

Plant at least 5 acres of non-B.t. cotton (as refuge cotton) for every 95 acres of B.t. cotton (95% B.t.,5% refuge). This refuge may not be treated with any lepidoptera-active insecticide labeled for the control of tobacco budworm, cotton bollworm or pink bollworm.

As required for the 5% embedded refuge option, the unsprayed refuge must average at least 150 feet wide (preferably 300 feet wide), and all associated B.t. fields must be within one-half mile (preferably one-quarter mile or closer), field border to field border, of the unsprayed refuge. These requirements apply to all 5% unsprayed option users regardless of the percent of cotton acres planted to B.t. in that county/parish.

Following is a list of the insecticide active ingredients that CANNOT be used on the refuge under this option:

acephate (>0.5 lb a.i./A) amitraz *emamectin benzoate endosulfan indoxacarb methomyl methoxyfenozide

methyl parathion profenofos (>0.5 lb a.i./A) pyrethroids sulprofos spinosad thiodicarb foliar B.t.k. products

pepper spray garlic spray Helicoverpa zea nuclear    polyhedrosis virus gossyplure

*Section 18 and/or Section 3 pending. Any recently labeled (Section 3 or Section 18) insecticide that has significant activity on Lepidopterous pests and not included in the list above, is restricted in the same manner as those insecticides listed above. Acephate and methyl parathion are allowed to be used in the refuge cotton as long as the application rate does not exceed 0.5 lb a.i./A per application.

If the refuge is to be planted in the same field as B.t. cotton, the refuge should be planted in a continuous block. Do not interplant rows of B.t. and conventional cotton for this option. Do not mix B.t. and non-B.t. seed for this option. Refuge cotton should be managed the same as the B.t. cotton to ensure a suitable host for susceptible insects throughout the season.

To avoid mixing seed in the planting process, be sure to clean all seed out of hoppers when switching from non-B.t. seed to B.t. seed, or vice versa.

In cases where placement of the refuge within one-half mile of the B.t. cotton would be in conflict with state seed production regulations, the grower must plant the refuge as close to the B.t. cotton as allowed.
