Vitaflo 280-Ascochyta of Pea

• Ascochyta of pea very different than Ascochyta seed infection of lentil and chickpea

• Causes seedling blight on pea

• Vitaflo 280 is extremely effective

• Ensure seed has higher germination and plump

Dr. K Chang-Alberta Agriculture

Thiram 75 WP on Peas

• Powder-inferior and dusty formulation

• Inexpensive

• Effective on Pythium, Ascochyta and Fusarium seed rot and seedling blight. Weak on Rhizoctonia

• Compatible with Nodulator Liquid (4 hr) and Peat (<4 hr)

Rhizobia and Seed Treatments

• Granular Rhizobia products have no restrictions on seed treatments and often produce higher yields especially under drier soil spring conditions

• Peat rhizobia for peas and lentils perform better for nodulation than liquids

• Check with Rhizobia manufacturer on any restrictions

• Avoid tank mixing seed treatment and Rhizobia

Rhizobia Compatibility with Vitaflo on PeaPea –Nodulator or So-Fast Peat • Vitaflo applied first and dried then Rhizobia

second- 4-6 hours for planting

• Vitaflo applied and simultaneous Peat Rhizobia applied- 2 hours window for planting

• Liquid are not recommended. Peat Rhizobia generally are more durable and produce more nodules than liquids

• No restrictions with Peat or Clay Granulars

CROWN ON LENTILS

• Provides superior control of Ascochyta compared to Apron Maxx RTA even when Crown applied at the low rate of 300 mL per 100 kg

• Crown is also labeled to control seed borne Botrytis, Fusarium and Rhizoctonia of lentil

• Pythium is minor pest on lentils so Crown can be applied alone

Ascochyta SuperiorControl Control?

CROWN ON CHICKPEAS

1) Must be applied with Allegiance (metalaxyl) or Apron XL to chickpeas for Pythium Control. This is a requirement to obtain coverage for Crop Insurance in Saskatchewan (90 % plant losses from Pythium on Kabuli Chickpeas is common).

2) Provides superior control of Ascochyta compared to Apron Maxx RTA even when Crown applied at the low label rate of 300 mL per 100 kg

3) Ascochyta can completely wipe out chickpea crop. To obtain crop insurance in Saskatchewan, seed level infection has to be at trace levels (Crown treated seed can be evaluated by lab).
