EFFECT OF SOIL AMENDMENT OF CLERODENDRUM-ACULEATUM AND CLERODENDRUM-FRAGRANS ON DISEASE INCIDENCE OF PIGEONPEA WILT

Plants of pigeonpea (Cajanus cajan) were treated with dry leaf powder of Clerodendrum aculeatum and Clerodendrum fragrans by soil amendement in two different sets respectively under glass house conditions. Cult ure filtrate of Fusarium oxysporium udum was inoculated in all the con trol and treated acts, A fetal of five soil amendment (two preinoculat ion anti three post-inoculation) treatments were given throughout the experiment. Alter sixty days of inoculation, 30% to 40% disease incide nce was recorded in treated sets, where as control plants showed 60% t o 65% disease incidence. Due to decrease in disease incidence, general increase in various morphological parameters was also achieved in tre ated sets. The best result In protecting pigeonpea crop from wilt path ogen and an increase in yield of around 4 times was obtained by soil a mendments with Clerodendrum aculaetum under glass house conditions.
