What else could it be
Condition | Similarities | Differences |
---|---|---|
Diagnosing spring drought in canola | Tipping | Drought makes plants more susceptible to heat stress, but it can occur when soil moisture is not limiting |
Diagnosing frost damage in canola | Tipping | Frost is a contrasting weather event that is easily distinguished from heat stress |
