Intervention effect Eforia efficacy was highest against A. pisum, then A. lineolatus and thrips, relative to cicadas.
Intervention effect Akarzin protected best against A. pisum, then A. lineolatus, relative to thrips and cicadas.
Observation Combined Eforia and Akarzin gave good insect pest control.
Observation The Eforia one-fifth reduced dose mixture with mineral oil had the highest toxicity.
Observation Eforia at a two-fifths reduced dose with Akarzin ranked next in efficacy.
Observation The mixtures showed subadditive synergism.

Fall cutting management affects yield and persistence of alfalfa in Atlantic Canada

G. Bélanger; T. Kunelius; D. McKenzie; et al. Canadian Journal of Plant Science 1999. doi:10.4141/p98-035

Other claims from this paper (10)

Intervention effect An additional harvest increased first-year seasonal DM yield by 1.6 to 2.3 t ha −1.
Intervention effect The yield benefit of an additional harvest declined over time, with no increase by the third production year.
Association Seasonal DM yield increased as the interval between final and previous harvest increased.
Intervention effect An additional harvest increased winter plant mortality at Truro and Nappan between years one and two.
Intervention effect An additional harvest increased winter plant mortality at St. John's between years three and four.
Intervention effect An additional harvest did not change winter mortality at Charlottetown and Fredericton or during the first three years at St. John's.
Intervention effect An additional harvest reduced next-year regrowth potential at Charlottetown and Fredericton and in the first three years at St. John's.
Intervention effect Oneida VR was more adversely affected by an additional harvest than Apica at Nappan and Truro after a severe winter.
Intervention effect An additional harvest increased the risk of winterkill in Atlantic Canada.
Recommendation The authors suggest that an interval of at least 500 growing degree-days might improve next-year regrowth.
