Other claims from this paper (9)
- Intervention effect Glyphosate at bolting reduced winter canola grain yield by 531 kg ha –1 versus untreated control.
- Intervention effect Glyphosate at early flower reduced winter canola grain yield by 488 kg ha –1 versus untreated control.
- Intervention effect Clethodim at early flower reduced canola yield by 185 kg ha –1 in 2017.
- Intervention effect Clethodim at early flower reduced canola yield by 280 kg ha –1 in 2018.
- Intervention effect Many late-season herbicide treatments significantly increased pod abortion.
- Association Yield decline with late-season herbicides was associated with increased pod abortion, although the authors considered other factors likely.
- Intervention effect Glyphosate at bolting decreased canola seed oil content.
- Intervention effect Glyphosate at early flower decreased canola seed oil content.
- Recommendation The authors recommend avoiding late-season herbicide applications, especially glyphosate, in winter canola.
