Soil
solarization was applied for a field which was planted with infected banana
seedlings. Spreading transparent plastic sheets of 80µ thickness was done from
August, 1 until October 12, 2017 at the University Farm in Jordan Valley. Soil
solarization was effective in elimination of all phytopathogenic propagules at 30 cm depth. Then clear
plastic sheets were removed and the solarized land was planted with healthy
banana seedlings cultivar Grand Naine. Banana plantlets were chemically treated
as soil drench with Nanoparticle solution of 200 and 400 ppm of Silver
Nanoparticles (AgNPs), two fungicides, Revanol and Tachigaren, Sodium Hypochlorite
in addition of irrigation of one treatment with treated wastewater. Biological
control included three treatments; Endomycorrhiza, Trichoderma as a
commercial product (BioHealth) and plant growth promoting rhizo-bacteria. Fresh
chicken and sheep manure was added to two treatments. Twelve treatments were
distributed randomly in randomized complete block design. Endomycorrhizal
inoculation with Glomus mosseae, 200 ppm of AgNPs, Revanol and
Tachigaren treatments of banana seedlings were the most effective in completely
protecting banana plants from Fusarium wilt during the whole experimental
period. Several applications of Trichoderma, wastewater and 400 ppm of
AgNPs were effective in maintaining some infected banana seedlings nine months
after planting very healthy. Sheep and chicken manure treatments resulted with
60 and 40% disease incidence with Fusarium wilt respectively and 20% of disease
incidence in Hypex, PGPR and control treatments. Wastewater, Nanoparticles 200 ppm
and endomycorhizal treatments gave the highest ratio of sword sucker
development. We recommend soil solarization and use of integrated program to
control Panama disease of banana in Jordan.
