Once the crop has emerged from the ground, the same crop protection concerns exist in zero tillage as in conventional tillage. Weed competition as well as disease and insect problems must be addressed in the same way in both systems.
Careful planning is essential.
Alternating broadleaf and cereal crops aids in breaking insect and disease cycles and control of volunteer crops as well as allowing more effective use of post emergent herbicides. Careful monitoring of crop conditions allows for proper identification of the nature and extent of weed, disease and insect problems. Proper product selection and use are important for successful crop production. Keep in the mind the availability of product tank mixes to reduce the number of operations.
