Introduction

Armyworms, belonging to various species within the genus Spodoptera, are a major threat in red gram cultivation. These caterpillars are voracious feeders, damaging red gram crops by consuming foliage and developing pods, which can significantly reduce yield and quality. Known for their rapid reproduction and destructive capabilities, armyworms present a formidable challenge in agricultural management. Effective strategies for control are crucial to minimize their impact on red gram production, ensuring sustainable crop yields and economic viability.

Symptoms

Armyworm infestations in redgram cause extensive damage by devouring foliage, leading to significant defoliation and reduced photosynthesis. They leave irregular patterns on leaves with ragged edges or partial consumption. Severe cases can result in complete leaf skeletonization, leaving only veins intact. Armyworms also threaten stems, causing lesions or breakage, especially in young plants. Their presence, noticeable during active periods like early morning or late afternoon, can stunt growth and reduce yields if not promptly managed. Early detection and intervention are crucial for effective control in redgram crops.

Preventive measures

To prevent armyworm infestations, farmers can employ effective strategies. Crop rotation disrupts their life cycle, while tillage exposes larvae to natural predators and adverse weather. Planting trap crops diverts armyworms from main crops, simplifying management. Early detection through regular field monitoring enables prompt action, reducing reliance on chemical treatments and supporting sustainable agriculture practices.

Chemical control

Karate is the widely used insecticide which controls broad spectrum of insect pests. Lambda Cyhalothrin 5 % EC will disturb their nervous system, causing paralysis and ultimately death of the pest. It comes in different forms for easy application but should be used carefully to protect the environment and also insects which are beneficial. The recommended dosage is 1.5 to 1.65 ml/liter of water (or) (330 ml/acre).

Plesiva insecticide made of  Cyantraniliprole 7.3% w/w + Diafenthiuron 36.4% w/w SC  controls a wide range of pests with its dual-action formula. Cyantraniliprole disrupts insect nervous systems, leading to paralysis and mortality in chewing and sucking pests. Diafenthiuron eliminates pests across all life stages through direct contact and reaches pests on leaf undersides.Promoting healthier crops, Plesiva is ideal for Integrated Pest Management (IPM), ensuring sustainable pest control strategies.The recommended dosage is 250ml/acre.

Proclaim Insecticide contains Emamectin Benzoate, part of the Avermectin insecticide family. It effectively controls caterpillars, thrips, and resistant pests. Applied as Emamectin Benzoate 5% SG, it moves through leaf tissues but doesn't spread throughout the plant. It works when insects eat it, causing paralysis and death within a few days. Proclaim also stops caterpillars from damaging crops shortly after application, lasting through light rain for up to 4 hours. It's safe for the environment, beneficial insects, and mixes well with other insecticides. The recommended dosage is 88gm/acre.
