Cultural methods - SS2 Agriculture Lesson Note

 

Crop Rotation: This involves changing the type of crops planted in a field each season. It disrupts the life cycle of pests and diseases that are specific to certain crops.

 

Planting Date and Density: Adjusting planting dates and spacing can affect pest and disease incidence. For example, planting earlier or later may avoid peak infestation periods.

 

Tillage and Weed Management: Proper soil preparation and weed control can reduce habitat and alternate hosts for pests and diseases.

 

Sanitation: Keeping the field clean by removing crop residues, weeds, and infected plants can minimize the source of pests and diseases.

 

Selection of Resistant Varieties: Planting crop varieties that are naturally resistant or tolerant to specific pests or diseases can be an effective preventive measure.
