| Sign of Attack / Symptom |
Control |
(i) Insect-Pests :
Termite : Attacks and kills young wheat plants in unirrigated areas in lower hills. |
1. Treat the seed with chlorpyriphos 20 EC @ 4ml/kg seed
2. Mix 2 litres chlorpyriphos 20 EC with 25 kg sand and apply in one hectare.
3. Remove stubbles of previous crop before sowing. |
| Grashopper : Causes damage to germinating crop by cutting the plants. Sometimes serious at lower elevations and in valley areas. |
1. Dust Follidol 2% dust @ 20-25 kg/ha
2. It is better to dust the grass on bunds and in waste land near the field before germination of wheat and barley as hopper migrate to germinating crop from these sources. |
| Armyworm : Feeds on foliage of young crop and attack shifts from one field to other |
1. Collect and kill the gregarious forms of caterpillars.
2. Spray 1125 ml Endosulfan 35 EC (Thiodan/ Hildon/ Endocin) or 750 ml Fenitrothion 50 EC (Folithion/Sumithion/Accothion) in 750 litres water. |
| Wheat bug : Appears in certain localized areas of Kullu and Kinnaur on milky grains and causes chaffyness of grains. |
Spray as above |
| Pod borer : Caterpillars feed on leaves and developing grains. |
Spray 1.5 L Endosulfan 35 EC (Thiodan/Hildon/ Endocel) in 750 litres water/ha |
| Wheat aphid : Aphids may cause severe damage by sucking sap from leaves and ultimately inhibiting grain formation. |
Spray 750 ml Methyl demeton 25 EC (Metasystox) or 750 ml Dimethoate 30 EC (Rogar) in 750 L water/ha. |
(ii) Diseases :
Yellowrust: Small,yellow coloured pustules arranged end to end in the form of stripes appear on the leaves and leaf sheaths. The rust is common in higher and mid hills where it causes much damage. |
1. In case of crop meant for seed purpose, spray with 0.2% Dithane M-45/Indofil M-45 (0.2%) at 15-day interval from first appearance of disease symptoms.
2. Plant resistant varieties
3.Spray Bayleton 25 EC, Tilt 25 EC (0.1%) or Contaf 5 EC (0.2%) |
| Brown rust : Scattered, round and brown coloured pustules appear on the leaves. The rust is common in low lying and valley areas. |
1. In case of crop meant for seed purpose, spray with 0.2% Dithane M-45/Indofil M-45 (0.2%) at 15-day interval from first appearance of disease symptoms.
2. Plant resistant varieties
3.Spray Bayleton 25 EC, Tilt 25 EC (0.1%) or Contaf 5 EC (0.2%) |
| Black rust : Dark brown pustules appear on stems, leaves and leaf sheaths. The teleuto sori are most commonly ruptured with fringed epidermis. The rust is common in areas adjacent to plains. |
