What Causes Yellow edges Disease on Maize?

Nutrient deficiency

The deficiency of magnesium catalyzes the Yellow edges disease in Maize, leading to chlorosis and often, wilting.

Imbalanced soil pH

An imbalanced pH, either too acidic or too alkaline, hampers nutrient absorption, particularly magnesium, thus encouraging the disease.

How to Treat Yellow edges Disease on Maize?

Non pesticide

Nutrient amendment: Enriching soil with magnesium-rich fertilizers or limestone can help alleviate the deficiency, mitigating disease impact.

pH correction: Regulate soil pH by either adding sulfur to reduce alkalinity or lime to decrease acidity, hence improving nutrient absorption.

Pesticide

Foliar spray: Apply foliar sprays rich in magnesium for immediate impact, but remember that it's a short-term solution.

How to Prevent Yellow edges on Maize?

Routine soil checks

Monitor and maintain soil health, especially its pH and nutrient levels, to prevent the onset of the disease.

Organic matter incorporation

Incorporate plenty of organic matter into the planting soil to improve its structure, nutrient content, and pH balance.

When is Yellow edges Most Active Period on Maize?

Yellow edges is most active during periods of rapid growth, especially amid conditions of high light intensity and dry, hot weather which often accelerates nutrient uptake issues.

Infectivity

Non

Yellow edges isn't spread between plants, hence it's non-infectious. It's conditioned by soil and environmental factors.

Lethality

Moderately

If untreated, Yellow edges can seriously impede Maize's growth and development, leading to decreased yield, but isn't usually lethal.

FAQs on Maize

Does Yellow edges disease affect Maize's yield significantly?

Yes, if untreated, the disease can significantly compromise Maize's yield by inhibiting photosynthesis and impeding growth.

Is Yellow edges disease contagious?

No, Yellow edges is non-contagious. It's determined by environmental and soil conditions, not through transmission between plants.

Can Yellow edges in Maize be cured completely?

Yes, applying the right amount of magnesium and balancing the soil pH can cure Maize from Yellow edges disease. Regular monitoring is needed to prevent reoccurrence.

Is pesticide necessary to treat Yellow edges in Maize?

Foliar sprays rich in magnesium can be considered as a 'pesticide' and provide immediate relief, but the primary focus should be on curing the underlying nutrient deficiency.

Can Yellow edges affect Maize at all growth stages?

Yes, though it's more prominent during rapid growth phases where nutrient demands are higher.

How can Yellow edges on Maize be prevented?

Regular soil health checks, proper nutrition management, and maintaining pH balance can help prevent the onset of Yellow edges in Maize.

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.

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.

Wilting is a disease that severely affects Maize, causing its leaves to droop and discolor. The disease interrupts normal water flow within the plant, thereby inhibiting growth and productivity and may potentially lead to the plant's death if not treated appropriately.

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.
