Other claims from this paper (8)
- Intervention effect Glyphosate at 75 or 150 g ae/ha applied to established alfalfa in the vegetative or bud stage usually reduced the yield of one cutting by 10 to 20%.
- Intervention effect Glyphosate applied in the vegetative stage affected the treated alfalfa foliage more than the postharvest regrowth.
- Intervention effect Glyphosate applied at the bud stage affected the regrowth following harvest of treated alfalfa foliage more than the treated foliage.
- Intervention effect Symptoms and the effect on alfalfa yield were greater at 300 g ae/ha than at the lower glyphosate rates.
- Observation Alfalfa always recovered from the glyphosate treatments, even at 300 g ae/ha.
- Intervention effect Applying glyphosate at 75 or 150 g ae/ha in each of two or three sequential alfalfa cuttings showed no cumulative effect.
- Intervention effect Glyphosate and SC-0224 had similar effects on alfalfa.
- Intervention effect Glyphosate and SC-0224 suppressed alfalfa much less than a severe infestation of dodder would.
