Selecting resistant hybrids
Sanitation: NLCB stays dorm in infected plant parts until weather conditions are favorable. NCLB infects newly planted corn through splashing water. Preparing the land with tillage practices and removing the previous season’s corn residue are essential for prevention.
The sooner the better: It’s easier and more cost effective to overcome NLCB and control it during the initial stage of infestation. Make it a routine to monitor the field regularly and search plants for the presence of the above symptoms on a weekly basis.
Proper soil drainage: The presence of standing water will promote the spread of NCLB. Make an effort and improve areas on the field where water tends to accumulate and form puddles. If possible, cover the ground with polyethylene sheets to reduce water evaporation from the soil.
