The sooner the better: It’s easier and more cost effective to overcome infestation by controlling rust in its initial stage. Make it a routine to monitor the field regularly and search plants for the presence of rusty-like symptoms on a weekly basis.
Maintain adequate space: Avoid overdensity planting in order to allow light to penetrate and promote the quick drying of leaves and fruits on humid days.
Sanitation: Remove plant debris and make an effort to keep your field and its surroundings as clean as possible.
Improve air circulation: Promote drying foliage by shortening the duration of wetting periods and introducing net curtain vented areas.
Other moisture reduction techniques include covering the ground with polyethylene sheets to reduce evaporation from the soil.
