Maize Downy Mildew Prevention

Maize downy mildew, caused by the fungus Peronosclerospora maydis, poses a significant threat to corn crops, leading to severe yield losses.

PRIMA Agro Tech’s innovative solutions utilise beneficial multi-strains of Bacillus tequilensis and Bacillus aryabhattai to provide an effective and sustainable approach to combat this disease, enhancing crop health and productivity.

About the Plant Disease

Maize downy mildew is a significant fungal disease that threatens corn crops globally. Caused by various species of the oomycete genus Peronosclerospora, this disease primarily targets young corn plants and can lead to substantial yield losses.

Prevention of maize downy mildew is crucial, as the disease can rapidly spread under favourable conditions, affecting large areas of corn cultivation. The disease thrives in moist and humid environments, particularly in regions with such climatic conditions. Effective prevention strategies are essential to protect corn crops and ensure healthy and productive yields.

Pathogen(s)

Peronosclerospora maydis is a significant fungal disease that primarily affects young corn plants, leading to considerable yield loss in corn crops. Peronosclerospora maydis attack young corn plants and can cause overall yield loss, posing a significant challenge for farmers. The pathogenic fungus enters the plant tissue and infects it at the crucial growth point.

The nature of this fungus to aggressively infect and spread within the plant tissues makes it a serious concern in corn cultivation.

Symptoms & Damage

The infection of Peronosclerospora maydis is identifiable by distinct symptoms:

Chlorosis: Infected leaves exhibit chlorosis, turning white and displaying stripes lengthwise parallel to the leaf vein
Stunted Growth: The growth of the corn plants becomes stunted. Infected leaves may roll and twist, showing abnormal growth patterns
Failure in Cob Formation: The most significant impact is on the plant’s ability to lower and form a cob, directly affecting the crop yield

Microbial Consortium

To combat Peronosclerospora maydis, PRIMA Agro Tech has developed solutions utilising specific strains of beneficial bacteria. These biological solutions offer a sustainable approach to managing Peronosclerospora maydis in corn cultivation. By leveraging the natural properties of these bacterial strains, PRIMA Agro Tech is committed to providing innovative and environmentally friendly solutions to enhance crop productivity and resilience.

Bacillus tequilensis strain 10b: This strain is employed for its ability to suppress the growth of Peronosclerospora maydis. It produces compounds that inhibit the fungus, protecting the corn plants from infection and aiding in maintaining healthy growth.

Bacillus aryabhattai strain B8W22: This bacterium enhances the corn plant’s natural defence mechanisms against Peronosclerospora maydis. Promoting the plant’s systemic resistance helps prevent the establishment and spread of the fungus.
