Sorghum
Soil insects:
- CRUISER or GUACHO
- ECO – T [Trico derma] or MYCO TECH.
- Treat seed with MARINURE DS or SEED START!
- Can be used with CRUISER or GAUCHO!!
Why seed treatment?
- Protects seed against insect attack.
- Root development.
- Fertilizer utilization especially Phosphorus and Nitrogen.
- Drought resistant and recovery after drought.
- Water utilization.
PRE-EMERGENCE HERBICIDES FOR GRASS CONTROL
- Relay or Metagan Gold can be used on Sorghum if the seed was treated with Concept.
- Concept must be included in Seed treatment process.
- Apply Herbicide directly after planting preferable 3 days from last soil movement.
READ THE LABEL AND CONSULT ME BEFORE USE!!
POST-EMERGENCE WEED CONTROL
- WEED-OFF at 2-3 litre per ha.
- GESAPRIM SUPER
- Excellent control. No scorch! No Phyto!!
NB: Apply on weeds 2-4 leaf stage!
FERTILIZER AND FOLIAR FEED SUGGESTION
- Soil in Panda inherently problematic.
- High Calcium and Magnesium.
- Low percentage Potassium. High pH.
Consider the following Fertilizer / Foliar programs
- MAP + UREA [ECO BLACK UREA] treated with ZINK SULPHATE. Can be coated!
- Use of MULTI MICRO GRAIN in the furrow.
- 20.7.3 or 5.1.5 as a compound granular fertilizer.
Foliar Feed
First application:
- MARINURE D.S 500 ml per ha + KNO3 1-2 kg per ha. Second Application (1-2 weeks before Flag leaf):
- MANIPLEX B or
- ULTRABOR + KNO3 or
- KNO3 + MULTI MICRO GRAIN or
- EASY FLOWER AND FRUIT 2-3 kg per ha.
STALK BORER
- Chilo and Basiola are present in Botswana!
- Early application of Insecticides is extremely important! Avoid high rates of low quality products!
- Reaching the insects is paramount to the success of the treatment! Use AQUAWETT!!!
- Using a quality wetter is extremely important!
- Water quality and pH are very important!
- Use KARATE ZEON or AMPLIGO or BULLDOG or DECIS FORTE [Avoid low quality Pyrethroids!!]
- Consider AMPLIGO as a new generation insecticide!!!
- Systemic product eg. ONCOL SUPER.
- Preferably the first application must be done before the infestation is noticed but before 2 % infestation!!! Usually 4-6 leaf stage.
- Use the highest water volume that is practical!
- Low water volumes are the reason for poor control!!!!!!
NORTHERN LEAF BLIGHT
- Early application, before signs is extremely important. Usually with second Stalk borer application.
- Protect Flag leaf at all cost!
- ARTEA
- AMISTAR TOP
- Both can be used with REGISTERED Stalk borer products and Foliar feeds as discussed.
APHIDS
- The use of quality pyrethroids e.g KARATE ZEON can limit the occurrence of Aphids!
- APHOX or DEMETON EC or DIMETHOATE.
BOLLWORM
- Methomex 200 gram per ha.
- Power up or Velocity Glypho at 0.5% of water volume will increase efficacy!
REMEMBER ALL APPLICATIONS:
- Maximum water volume.
- pH correction.
- Use Aquawett when needed!
