Pigeonpea (Cajanus cajan (L.) Millsp.) is the important legume crop in india. Wilt complex of pigeonpea is major constraint in pigeonpea production caused by Fusarium udum, Rhizoctonia bataticola and Phytophthora drechsleri f. sp. cajani. The experiment was carried out at research fields of Dr. PDKV, Akola in Kharif 2023-24 for the management of pigeonpea wilt complex by using Trichoderma asperellum and Metalaxyl 4%+ Mancozeb 64% WP (Ridomil gold MZ) with seven treatment combinations. Experiment was carried out in three fields with different cropping patterns viz., pigeonpea sole, pigeonpea - soybean and pigeonpea - cotton intercropping. Per cent wilt incidence observed in pigeonpea sole cropping (42.66%) was higher in absolute control at 150 DAS than in intercropping with soybean (35.66%) and cotton (34%). Among seven treatment combinations lowest disease incidence was observed in T₆- seed treatment with Trichoderma asperellum and Carboxin 37.5% + Thiram 37.5% DS and three times foliar spray of Metalaxyl 4% + Mancozeb 64% WP in all three cropping patterns viz., pigeonpea sole (19.66%), pigeonpea - soybean (16%) and pigeonpea - cotton (14.66%) with the highest per cent disease control 53.91, 55.13 and 56.88% respectively. Followed by T₄- seed treatment with Trichoderma asperellum and Carboxin 37.5% + Thiram 37.5% DS and soil application of Trichoderma asperellum at the time of sowing, 30 and 60 DAS which had also shown good results with per cent disease incidence 22, 18 and 16.33% respectively in pigeonpea sole, pigeonpea - soybean and pigeonpea - cotton with per cent reduction of disease over control 48.42, 49.52 and 51.97% respectively.
