Introduction

Aphids, belonging to the order Hemiptera, are small, sap-sucking insects commonly found in cotton fields globally. They present substantial challenges to cotton production due to their rapid reproduction and ability to transmit viral diseases. By using piercing-sucking mouthparts, these pests feed on plant sap, leading to weakened cotton plants and decreased vigor. Aphids thrive particularly in warmer climates, posing economic risks through impacts on plant growth and quality. Effective management strategies are essential to mitigate their influence on cotton crops and sustain optimal yield potential.

                   

Symptoms

Presence of sticky honeydew on leaves and other plant parts, which can lead to the growth of black sooty mold. Additionally, cotton plants infested with aphids may exhibit distorted or curled leaves, stunted growth, and reduced vigor. While these symptoms can indicate aphid presence, it's important to confirm their presence through visual inspection or monitoring methods before taking further action.

 

Preventive measures

To control aphids in cotton, promoting natural predators like ladybugs and lacewings helps reduce their numbers. Crop rotation with non-host plants disrupts aphid life cycles effectively. Reflective mulches or aluminum-coated plastic can deter aphids by confusing them visually and reducing their presence on cotton plants. Regular monitoring for early signs of aphids and applying insecticides when needed are crucial for maintaining cotton yield and quality.

Chemical control

Confidor insecticide is made of Imidacloprid 200 SL (17.8 % w/w) is the most powerful insecticide against a wide variety of pests.It is easy to apply, safe to plants and also compatible with other insecticides. The recommended dosage is 0.5 ml/lit of water for spraying (or) 100ml per acre.

 

Acemain insecticide containing Acephate 75% SP, is a versatile organophosphate insecticide highly effective against severe infestations of chewing and sucking insects.It has low toxicity to mammals and does not harm beneficial insects. Being water-soluble, Acemain is easy to use and offers broad-spectrum systemic control. The recommended dosage is 2gms/lit.

Actara insecticide is one of the fast eliminating insecticide of sucking and chewing pests,by stoping damage to crop before it is started in crop.It reduces the chance of pest resurgence. Thiamethoxam 25% WG will disrupts the nerve transmission, which leads to paralysis and ultimately death of the pest.The dosage recommendation 0.5 gm/Lit of water or 100gms in 200Lit of water per acre.
