MANAGEMENT OF CHILLI ANTHRACNOSE/DIE-BACK OR FRUIT ROT BY SYSTEMIC ACQUIRED RESISTANCE ACTIVATORSJaiman R.K., Acharya S.K., Pathan N.P. , Desai H.A. and Patel A.M.Abstract Chilli is an important spice, vegetable as well as cash crop of Gujarat, mostly cultivated in Kharif season, which is quite remunerative to farmers. Chilli is prone to several diseases, but anthracnose is a most devastating caused by fungus Colletotrichum capsici (Sydow) Butler and Bisby and one of the major constraints in chilli cultivation throughout the world. In the present study various systemic acquired resistance activators tested against chilli anthracnose during 2018, 2019 and 2020 at College of Horiculture, S.D. Agricultural University, Jagudan, Mehsana Gujarat. Data clearly revealed that minimum per cent disease intensity and highest green chilli yield was observed in seed soaking + foliar spray of Azoxystrobin 1000 ppm which was at par with seed soaking + foliar spray of Salicylic acid (SA) 100 ppm during individual year and pooled data also. Azoxystrobin and Salicylic acid (SA) induced systemic acquired resistance by increasing defense enzymes peroxidase (PO), polyphenol oxidase (PPO), phenylalanine ammonia lyase (PAL), ï¢-1, 3 glucanase, chitinase, catalase and defense-inducing chemicals (total phenols). Azoxystrobin is also registered in CIBRC for management of chilli anthracnose with PHI 5 days. |
