Harvest Aid

carfentrazone (Aim EC)

Rate 0.016 to 0.096 lb ai/a (1.0 to 6.1 oz/a Aim EC)

Time Apply at maturity when 80 to 90% of seed pods are yellow or buck skin color and only 30% of green leaves remain on the plant.

Remarks Can be applied up to 0 days before harvest. Use a minimum of 15 gal of finished spray per acre for ground application and 5 gal per acre for aerial application. MSO or COC is required at 1 to 2% v/v. The addition of liquid nitrogen fertilizer at 2 to 4% v/v may enhance performance.

Caution Do not apply more than 6.1 oz/a per season.

Site of action Group 14: protoporphyrinogen oxidase (PPO) inhibitor

Chemical family Triazinone

glyphosate (several trade names)

Rate 0.6 to 2.25 glyphosate ae/a (product rate will vary depending on formulation)

Time Apply to crop at the hard dough stage.

Remarks Preharvest interval is 7 days.

Caution Only certain formulations are labeled. See label for adjuvant use. Do not feed treated vines or hay to livestock.

Site of action Group 9: inhibits EPSP synthase

Chemical family None generally accepted

paraquat (Gramoxone SL 2.0 or other trade names)

Rate 0.3 to 0.5 lb ai/a (1.2 to 2 pints/a Gramoxone SL 2.0)

Time Apply when crop is mature: this means at least 80% of pods are yellowing and mostly ripe with no more than 40% of leaves still green.

Remarks Use with a nonionic surfactant at 0.25 % v/v. Split applications permitted. Do not exceed two applications per season or 2 pints/a of Gramoxone SL 2.0. Apply in at least 20 gal/a water by ground or in at least 5 gal/a water by air. Caution A restricted-use herbicide. Do not allow drift from target site. Do not apply within 7 days of harvest.

Site of action Group 22: photosystem I electron diversion

Chemical family Bipyridilium

saflufenacil (Sharpen)

Rate 0.022 to 0.044 lb ai/a (1.0 to 2.0 oz/a Sharpen)

Time Apply over the top of garbanzo beans that have reached physiological maturity (at least 80% yellow/brown pods and no more than 40% of leaves are still green).

Remarks Allow up to 10 days for optimum desiccation effect. Thorough spray coverage and an MSO plus ammonium-based adjuvant system are required for optimum desiccation.

Caution Maximum cumulative amount per cropping season for desiccation uses is 2.0 oz/a. Do not apply within 2 days of harvest.

Site of action Group 14: protoporphyrinogen oxidase (PPO) inhibitor

Chemical family Uracil
