Edible Bean School: Timing desiccation for maximum yield & quality

[ad_1]

Whether or not undercutting or direct harvesting edible beans, a pre-harvest software of a desiccant can enable for a faster harvest, whereas defending yield and quality.

Correct desiccation timing is essential for maximizing the crop’s potential, explains Calem Alexander, discipline marketer with Hensall Co-op, on this Edible Bean Faculty episode centered on setting the crop up for harvest.

“We’re looking for overall maturity in the plant, 80 to 90 per cent leaf drop, you want to see about 90 per cent of the pods change to that yellow, buckskin-type colour, and in the pod, you want to make sure 90 per cent don’t have green left in the meat of the bean, and it’s turned white inside,” he explains, standing in a discipline of navy beans close to Miami, Manitoba.

As for which product to make use of, at all times seek the advice of your purchaser to seek out out which chemistries are eligible, Alexander emphasizes. Glyphosate, for instance, is not an possibility for most consumers.

“One of the most widely-used and common products available for a pre-harvest desiccant is saflufenacil,” he notes. “It’s a great product for doing a fall dry-down in dry beans.”

Saflufenacil, which is a contact herbicide, is offered underneath a number of completely different names, relying on geography — it’s generally known as Warmth in Western Canada, Eragon in Ontario, and Sharpen within the U.S.

“There are a few things we can do to make it work better. Proper timing being the first one. Use lots of water — we’re shooting for 20 gallons per acre. Spraying during the heat of the day will improve its efficacy, and use of a deposition aid like Interlock will always help out the job as well,” explains Alexander.

BASF, the producer of Warmth and Eragon, additionally suggests avoiding purposes when it’s hazy or smoky, as has been the case for prolonged intervals in western bean rising areas this season.

Desiccation timing will also be sophisticated by extraordinary rising circumstances. In Ontario, there are studies of pods nearing maturity whereas vegetation nonetheless have loads of inexperienced leaves, possible on account of ample moisture. It’s a special story in Western Canada and the Northern Plains, the place excessive warmth and drought stress have resulted in variable in-field maturity.

“The parts of the field where the plants had a little better life cycle are maturing normally and look good, but the areas of the field that were more stressed are staying greener a little longer,” notes Alexander. “Ideally, you want to shoot for the middle ground and hit the majority of the field at the right timing.”
