मूंग फसल कीट नियंत्रण गाइड: पूरा स्प्रे शेड्यूल

Moong crop is most damaged by sap-sucking insects, caterpillars and pod borers. If not sprayed on time, the yield can drop by 30-40%. Here is a complete schedule of which pest comes at each stage, from sowing to pod formation, and which medicine to apply when.

Problem Identification (Life Cycle and Causes)

Pest attack in moong crop depends on weather and crop stage:

• 20-30 Days (DAS): The plant is small and tender. During this time, sap-sucking pests like aphids, jassids and thrips suck the sap from the leaves, weakening the plant. Warm and humid weather is favorable for them.
• 40-50 Days (DAS): Leaf-feeding caterpillars become active. They make the leaves sieve by piercing or eating them from the edges.
• Flowering Stage (50% Flowering): Pod borer caterpillar (Helicoverpa armigera) lays eggs in flowers and new pods. As soon as the larvae emerge, they enter the pod and start eating the grains.
• Pod Formation Stage: Along with pod borer, pod fly also damages the grains from inside by making holes in the pods.
• At any stage: Whitefly may appear, which is the main cause of spreading Yellow Mosaic Virus.

Symptoms

• Yellowing and curling of leaves (effect of aphids, jassids, thrips)
• Small holes on leaves or leaves cut from the edges (effect of caterpillars)
• Shedding of flowers and small pods
• Holes on pods and grains eaten from inside (pod borer, pod fly)
• Yellow-green mottled pattern on leaves (sign of Yellow Mosaic Virus)
• Stunted plant growth and sticky substance (honeydew) appearing on leaves

Crop Damage

• Sap-sucking pests reduce plant vigor, leading to fewer flowers
• Caterpillars reduce photosynthesis (food production process) by eating leaves
• Pod borers and pod flies directly damage the grains, reducing both yield and quality
• If Yellow Mosaic Virus spreads, the entire field can be affected, leading to a significant drop in yield

Treatment Methods

Cultural (Agricultural Measures)

• Sow on time so that the sensitive stage of the crop can avoid the period of pest infestation
• Keep the field and bunds clean, weeds harbor pests
• Uproot and destroy infected plants at the initial stage, especially those with Yellow Mosaic Virus

Biological (Biological Measures)

• Install yellow sticky traps, which helps monitor and control whiteflies and thrips
• Pheromone traps provide information about the presence of pod borers, helping in deciding timely spray
• Use mild sprays initially to protect beneficial insects like ladybug beetles

Chemical (Chemical Treatment): Stage-wise Spray Schedule

20-30 DAS: Aphids, Jassids, Thrips and all sap-sucking pests Spray Thiamethoxam 25% WG. It is a systemic insecticide that kills sap-sucking pests by entering the plant and its effect lasts for a long time. For dosage and complete information, see product page: KrishiKranti Thiomax - Thiamethoxam 25% WG

40-50 DAS: Leaf-eating caterpillars Spray Cartap Hydrochloride 50% SP. It enters the caterpillar's stomach, immediately stops it from eating, and provides quick control. To know the dose, see: KrishiKranti Tapride - Cartap Hydrochloride 50% SP

50% Flowering Stage: Pod borer caterpillar (Helicoverpa armigera) Spray Chlorantraniliprole 9.3% + Lambda Cyhalothrin 4.6% ZC. This is a dual action insecticide, effective at both egg and larval stages, and protects the pods. Complete information on dose and use: KrishiKranti Cuba - Chlorantraniliprole 9.3% + Lambda Cyhalothrin 4.6% ZC

Pod Formation Stage: Pod Borer and Pod Fly Spray Novaluron 5.25% + Emamectin Benzoate 0.9% SC. It inhibits larval growth and is also effective against pod fly, protecting the pods from inside. See full details here: Ghatak - Novaluron 5.25% + Emamectin Benzoate 0.9% SC

At any stage: If whiteflies (vectors of Yellow Mosaic Virus) are seen Spray Imidacloprid 30.5% SC and uproot and destroy infected plants at the initial stage. This prevents further spread of the virus. See dose: Immediate - Imidacloprid 30.5% SC

Always spray as per the recommendations given on each spray label. Always read the medicine label and determine the dose accordingly.

When and How to Use Medicines

• Always spray in the morning or evening, the effect of spray is reduced in strong sunlight
• Use a flat fan type nozzle and sufficient water in a knapsack sprayer, so that the medicine reaches the underside of the leaves
• Do not apply the same medicine repeatedly, it can build resistance in pests
• For useful medicines for all caterpillars and sap-sucking pests of moong, see Insecticides Collection for Moong

Prevention Tips

• Regularly monitor the field, check plants at least twice a week
• Identify pests early by installing yellow sticky traps and pheromone traps
• Apply balanced fertilizer, excess nitrogen makes the plant tender and attracts pests
• Remove weeds and old crop residues around the field
• Practice crop rotation, do not plant moong continuously in the same field
• Immediately uproot and destroy infected plants outside the field

Frequently Asked Questions (FAQs)

When should I spray for aphids and jassids in moong?

In 20-30 day old crop, when sap-sucking pests are seen, Thiamethoxam 25% WG should be sprayed.

How to identify pod borer caterpillar in moong?

If small holes are seen on the pods and the grains are eaten from inside, it is a symptom of pod borer (Helicoverpa armigera).

How does Yellow Mosaic Virus spread in moong?

This virus is spread by whiteflies. It can be stopped by spraying Imidacloprid and removing infected plants.

At what interval should spraying be done in moong?

Generally, monitor at an interval of 15-20 days depending on the stage of pest attack and spray if necessary.

Can the same insecticide be applied repeatedly?

No, this can lead to resistance in pests. Use a medicine with a different mode of action at each stage.
