Basil Seed
Research using - University Of Florida
(Trial 3)
Protocol & Applications Rates:
April
16th
Two varieties of basil seeds
(Genovese: susceptible cultivar) & (Nufar: resistant cultivar) were planted
in a peat medium. PGA Plus was applied as a soil drench to half of the seeds of
each basil cultivar at a rate of 1 lb. / 100 gallons of water. Controls
received only water.
June
5th
Seedlings were transplanted
into the fieldand drenched again at the same rate. The soil was a sandy loam
containing 2.8 % organic matter. Throughout the crop cycle PGA Plus was
reapplied at 2 week intervals. Transplants were fertilized at planting and
weekly with a water soluble fertilizer (20 - 10 - 20) at a rate which furnished
the plants 200 ppm N. A randomized complete block design with four replications
was used.
Plants were monitored weekly for
symptoms of Fusarium wilt and symptomatic plants were assayed for Fusarium
(predominantly Fusarium oxysporum) and other fungal species using a fusarium -
selective medium (Komada's medium). Data was analyzed using Fisher's Protected
LSD.

Interpretation of Test Results - Basil treated
with Organica's Plant Growth Activator Plus showed a drastic decrease in the
incidence of Fusarium wilt (93 % in Genovese) and a significant increase in
yield (29.4 % in Genovese).
Both the susceptible and resistant
varieties benefited from applications of Plant Growth Activator Plus.
Furthermore PGA PLUS reduced root discoloration and the incidence of foliar
bacterial blight (Xanthamanas sp.)
