Pea (Pisum sativum) is an
important fibrous vegetable crop. The present research was designed to
assess the edaphic factors involved in wilt of pea progression. Different
genotypes were evaluated against wilt disease under field conditions.
Comparative efficacy of three different systemic resistance inducers i.e.
Salicylic Acid (SA), NaH2PO4 and KH2PO4
were evaluated against the disease at the rate of 1 and 3% under field
Negative linear trend was seen between the AUDPC units and rainfall. With
the increase of the rainfall, decrease in disease incidence was observed.
Maximum AUDPC units were recorded at 0.0 to 0.2 mm rainfall. Linear
positive trend was observed between AUDPC units and the soil temperature,
maximum AUDPC units were recorded at 17.0 to 17.25oC. With the
increase of sunshine time, increase in AUDPC units was observed, maximum
AUDPC units were recorded when sunshine period was between 24750 to 25200
seconds. From seventeen pea genotypes, none was found immune to the
disease. Salicylic acid at 3% was found most effective to lower the
disease incidence with 7 days interval.
