Abstract

Effectiveness of fungicides, methanolic botanical extracts and antagonists against invasive P. palmivora inciting leaf spots of Chinese fan Palm was carried out.  Best fungicide in restraining the development of the organism, in plunging request were Range, Difenconazole, Acrobat MZ, Precure and Thiophenate methyle as they caused 100, 100, 97, 92 and 91 percent decrease over the control in mycelial development of P. palmivora. While, Propmeb, Sulfur and Mancozeb were slightest powerful in hindering the mycelial development of parasite as they caused 41, 35 and 33 percent lessening in mycelial development. Best methanolic plant extricates in restraining the development of the organism, in plummeting request were Moringa Leaf Concentrate, Neem Leaf Concentrate, Akk Leaf Concentrate, Garlic Concentrate and Datura Leaf Concentrate as they caused 87, 86, 76, 76 and 70 percent diminishment over the control in mycelial development P. palmivora, separately. There was continuous trend of reduction in mycellial growth with increase in fungicide and methanollic plant extract concentration. All the antagonistic microorganisms reduced the mycelial growth of P. palmivora significantly. Pseudomonas fluorescence has produced largest inhibition zone (5.5 mm) followed by Penicillium spp. which has produced (5 mm) inhibition zone. Basillus fortis was the third most effective antagonist against P. palmivora with 4.5 mm inhibition zone. Aspergilus nigar proved to be least effective antagonistic microorganisms which has produced 2 mm inhibition zone as compared to other antagonists.
