Abiotic constraints in Wheat
Abiotic in-crop constraints for wheat
Groups D J herbicide damage
Constraint – Group D/J herbicide damage
- Reduced or poor seedling emergence
- Shortening and thickening (Group D) of coleoptile so that emerging leaves are unable to reach the soil surface
- Emerged shoots are often swollen and bright green (Group J), or have twisted and distorted leaves (Group D)
- Roots are often short and thick with stubby or spade like tips
There are no treatment options, plants either die or completely recover. As a precaution, pray when environmental conditions are optimal, and avoid spray drift.
