Overview
Barley Integrated Crop Protection Recommendations
Common Barley Diseases
1. Net Blotch (Fungal)
-
Damage: Reduces yield and grain quality.
-
Symptoms: Brown lesions with net-like patterns on leaves.
-
Control: Spray Pyraclostrobin 20% SC or Propiconazole 25% EC.
2. Leaf Rust (Fungal)
-
Damage: Causes significant yield loss.
-
Symptoms: Orange-brown pustules on leaves and stems.
-
Control: Apply Triadimefon 25% WPÂ or Azoxystrobin 25% SC.
3. Powdery Mildew (Fungal)
-
Damage: Weakens plants and reduces grain fill.
-
Symptoms: White powdery patches on leaves.
-
Control: Use Tebuconazole 25% EWÂ or Sulphur 80% WG.
4. Bacterial Leaf Streak (Bacterial)
-
Damage: Reduces photosynthetic area.
-
Symptoms: Water-soaked streaks turning brown on leaves.
-
Control: Apply Copper Oxychloride 50% WPÂ or Kasugamycin 2% SL.
Common Barley Pests
1. Aphids (e.g., Bird cherry-oat aphid)
- Impact: Transmit viral diseases (e.g., BYDV).
- Damage Symptoms: Yellowing and stunting of plants; rolled leaves.
- Control Measures:Spray Imidacloprid 20% SLÂ or Acetamiprid 20% SP
2.Stem Borers
- Impact: Tunneling in stems
- Damage Symptoms: Dead hearts, wilting
-
Control Measures: Use Fipronil 5% SCÂ or Cartap hydrochloride 50% SP
3. Armyworms
-
Impact: Defoliation, yield loss
-
Damage Symptoms: Ragged leaves, visible larvae
-
Control Measures: Apply Chlorpyrifos 48% ECÂ or Emamectin benzoate 5% SG
4. Red Spider Mites
-
Impact: Cell content feeding
-
Damage Symptoms: Yellow stippling, webbing
-
Control Measures: Spray Abamectin 18 g/L ECÂ or Propargite 57% EC
Common Weeds in Barley Fields
1. Wild Oats
-
Damage: Nutrient competition, yield reduction
-
Symptoms: Similar to barley but with twisted leaves
-
Control: Spray Clodinafop-propargyl 15% WPÂ post-emergence
2. Striga (Witchweed)
-
Damage: Parasitism, severe yield loss
-
Symptoms: Yellowed leaves, attached pink roots
-
Control: Apply Glyphosate 360g/l SL pre-planting
3.Field Bindweed
-
Damage: Smothers crops, reduces light
-
Symptoms: Arrow-shaped leaves, white flowers
-
Control: Use Metsulfuron-methyl 20% WPÂ early growth
4. Johnson Grass
-
Damage: Aggressive spread, resource competitor
-
Symptoms: Broad leaves, rhizome roots
-
Control: Apply Quizalofop-p-ethyl 10% ECÂ at tillering
