What Causes Wilting Disease on Maize?

Pathogen

Wilting in Maize is primarily caused by a bacterium called Erwinia tracheiphila, which enters the plant through beetle bites or plant abrasion and restricts water movement.

Environmental Factors

Overwatering, poor soil drainage, and high ambient temperature can also lead to wilting in Maize by causing root damage and plant stress.

How to Treat Wilting Disease on Maize?

Non pesticide

Proper watering: Ensure optimum watering levels, avoiding both overwatering and underwatering, to maintain healthy root health and boost plant immunity.

Crop rotation: Rotate Maize with non-host plants to disrupt the life cycle of bacteria and lower the disease's prevalence.

Pesticide

Antibacterial sprays: Application of antibacterial sprays can control the bacteria causing the wilting. Ensure to follow the manufacturer's instructions for best results.

Insecticide application: Insecticides can be used to control beetle populations, thereby reducing the risk of disease transmission.

How to Prevent Wilting on Maize?

Regular monitoring

Monitor the Maize regularly for early signs of wilting to ensure early detection and management.

Sanitize tools

Clear garden tools and equipment after use to prevent the spread of the bacteria.

Improved soil drainage

Improve the soil's drainage capability to prevent water-logging which could cause root damage and facilitate bacterial infection.

When is Wilting Most Active Period on Maize?

Wilting disease is most active during the hot, dry periods of the year as the bacteria thrive in these conditions and plants face more water-stress exacerbating the susceptibility.

Infectivity

Highly

Wilting disease is highly infectious. The bacteria can spread rapidly from plant to plant through rainwater, garden tools, or insect vectors.

Lethality

Moderately

Left untreated, wilting can severely affect Maize's growth and productivity, often leading to plant death. However, early detection and treatment can prevent losses.

FAQs on Maize

What does Wilting look like in Maize?

The plant exhibits symptoms such as yellowing and drooping of leaves, brown stripes on the leaf veins and, in the final stages, the plant becomes limp and discolored.

Can wilting disease kill Maize?

Yes, if left untreated, wilting can severely inhibit growth and lead to the death of the plant. But early detection and effective treatment can prevent this.

How is wilting disease spread?

Wilting is primarily spread by a bacterium, Erwinia tracheiphila, which can be easily transferred from plant to plant through garden tools, rainwater, or insect vectors like beetles.

Can Maize recover from wilting?

Yes, with proper care, treatment, and removal of affected plant parts, Maize can recover from wilting.

What is the best environmental condition for Maize to prevent wilting?

To prevent wilting, ensure Maize has optimal watering levels, good soil drainage, and moderate temperature.

Why is Maize wilting despite regular watering?

Overwatering can actually cause wilting by damaging the roots and facilitating bacterial infection. Ensure adequate drainage and water only when necessary.

Other Common Problems About Maize

MainImg

Brown spot is a fungal disease affecting Maize, leading to yield reduction and quality loss. Its primary cause is the pathogen Bipolaris maydis, and it is most active in warm, damp conditions. Though moderately infectious, it's lethal on a smaller scale.

MainImg

Leaf rot is a detrimental disease affecting Maize, causing serious damage to its leaves. The disease, usually perpetrated by various fungi, interferes with photosynthesis, stunting growth, and decreasing yields.

MainImg

Caterpillars significantly affect Maize, causing damage leading to reduced output and hampered growth. They consume the foliage, bore into the cobs, and disrupt the plant's photosynthesis process. These insect larvae can greatly impact yield quality if left unchecked.

Rust mold in Maize is a fungal infection causing discoloration, stunted growth, and potential yield reduction. Effective management is critical to minimize economic and agronomic impact.

Leaf Spot is a disease that significantly affects Maize, leading to yield loss. It's caused by a group of fungi that create noticeable brown, gray, or black spots on the plant's leaves. High moisture and moderate temperatures facilitate disease spread.

Leafminer stripe

Leafminer stripe is a significant disease affecting Maize, causing stunted growth and reduced yield. The disease often results in leaf discoloration and poor corn ear development. It's caused by pests, typically prevalent in warmer climates, but can inflict damage throughout the growing season.

Yellow edges is a destructive condition affecting Maize, triggered by nutrient deficiencies, specifically a lack of magnesium, and imbalanced pH. This disease can cause significant yield loss and poor crop quality if left untreated.

Large spot mold

Large spot mold, caused by the fungus Bipolaris maydis, is a disease that affects Maize, causing potential loss of yield. It leads to oblong to circular grayish green lesions on the leaves, signaling severe infection.

Lack of fertilizer

Lack of fertilizer profoundly affects Maize by stunting growth, reducing yields, and causing malnutrition. Caused by insufficient nutrient supply, this non-contagious, low lethality condition can dramatically impact plant health and productivity if left unchecked.

Leaf tip withering

Leaf tip withering is a detrimental disease affecting Maize, resulting in dehydration and impaired photosynthesis. It's primarily caused by inadequate watering and nutrient imbalances. The disease, left untreated, can be lethal and is moderately infectious amongst the same species.

Fruit rot is a severe disease affecting Maize, leading to significant yield loss. Resulting from fungal growth, primarily due to high humidity and rainfall, this condition causes discolouration, wilting, and decay of the fruit. Effective management is crucial to maintain crop health.

Leaf yellowing in Maize indicates a decline in chlorophyll, affecting photosynthesis and potentially leading to stunted growth and reduced yield.

Crown gall is a bacterial plant disease that causes tumour-like growths mainly on the stem of Maize. It hampers the normal growth and development, thus hugely impacting yield quality and quantity.

Dark spots is a fungal disease affecting Maize causing spots on leaves that can stunt growth and reduce yield. Its cause, symptoms, activity period, and control methods vary, requiring informed prevention and management.

Leaf wilting in Maize significantly affects the plant's vigor, productivity, and overall development, leading to severe yield reductions if untreated. It involves premature sagging and dehydration of leaves due to insufficient water supply or damage.

Dark blotch is a fungal disease affecting Maize often resulting in significant damage to the leaves, affecting photosynthesis, and drastically reducing yield. Caused by Alternaria alternata, it thrives under wet, warm conditions and can quickly spread in dense canopies.

Rust disease, scientifically known as Puccinia coronata causing severe decay, primarily affects Maize. This fungal disease triggers substantial yield loss and quality degradation. It is highly infectious, moderately lethal, and requires both cultural practices and chemical treatments for control and prevention.

Stem rot is a destructive disease affecting Maize cultivation, leading to substantial losses. Characterized by a soft, wet rot of stems, it hampers plant growth and crop productivity. The disease emerges due to fungal pathogens and is favored by moist, humid conditions.

Whole leaf withering

Whole leaf withering is a devastating disease that affects Maize, causing extensive damage and reducing crop yield. The disease is fueled by certain pathogens and environmental factors, manifesting through symptoms like leaf curling and discoloration.

The 'Caterpillar' disease refers to damage from caterpillar infestations on Maize, leading to reduced crop yield and vitality. These pests primarily eat the leaves, affecting the plant's ability to photosynthesize.

Fruit malformation

Fruit malformation is a prominent disease affecting Maize, leading to distorted grain shape and size, possibly reducing yield. It primarily attacks during kernel formation stage, caused by Fusarium spp., weather destroyers, and nutrient imbalance.

Aphids are common pests impacting Maize, causing nutrient loss and stunted growth. These small insects extract sap, weakening Maize and facilitating viral transmissions.
