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
Ascochyta of Pea Germination Cold Temperatures Soil
Vitaflo 280-Rhizoctonia of Pea Soil borne disease Causes seedling blight on pea An important yield robber in pulses Vitaflo 280 is extremely effective

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 Pea Pea –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 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).

Trilex Al for Ascochyta Control on Chickpeas Ascochyta resistance is widespread to Group 11 fungicides. Trilex Al would be ineffective against these strains Crown is the only product that provides a high level of control of ascochyta of chickpeas Have ascochyta on seed, Crown is the only choice!!
