Abstract

Chili ( Capsicum annuum L. ) is the fruit of plants, the Chili is susceptible for several diseases and seed borne fungi Phytophthora capsici which produces collar rot and root of chili. Seed borne pathogens are associated with untreated seeds of chili which are also significantly reduced the germination of seed. This experiment was conducted to find out the seed borne fungi and enhanced the germination of chili ( Capsicum annuum ) with two fungicides known as Mancozeb 80% WP and Carbendazim 50% WP. Effectiveness of these two fungicides were measured when the seeds planted on blotter paper in petri plates at 27 0 C under lab conditions. These two fungicides significantly reduce the effect of seed borne fungi associated with chili seeds. Mancozeb 80% WP was found most effective to reduce the effect of seed borne fungi and increase the seed germination. Considering the results of the experiment, Mancozeb 80% WP was noted to be a best fungicide against the seed borne fungi.

Highlights

Chili (Capsicum annuum L.) is the fruit of plants from the genus ‘Capsicum’, members of the nightshade family, ‘Solanaceae’ (Asaduzzaman et al 2010), widely growing in all season and all areas of Pakistan
Highest seed germination was recorded in Mancozeb 80% WP, 82% germination and lowest germination was recorded in control condition 53%
Highest healthy seed germination was recorded in Mancozeb 80% WP at conc. (1.562gm 100% and 0.39gm 97.32% healthy plants and 1.562gm 0% and 0.39gm 2.68% infected plants) infected plants in control condition was 46.68%

Summary

Introduction

Chili (Capsicum annuum L.) is the fruit of plants from the genus ‘Capsicum’, members of the nightshade family, ‘Solanaceae’ (Asaduzzaman et al 2010), widely growing in all season and all areas of Pakistan. Chili (Capsicum annum L.) is an important vegetable crop planted over an estimated area of 47.3 thousand hectares with an annual production of 69.5 thousand tones, with an average yield of 1902 kg/ha in Pakistan (Anon 2006). Chilies are widely grown as cash crop, spice and vegetable crop in the tropical and subtropical regions. (Hemannavar 2008 & Than et al 2008). Capsicum annum (frutescens) exists as an annual herbaceous vegetable or perennial shrub of the Solanacae (Amusa et al 2004). Chilies production of 7.18 million tons over an area of 1.7 million ha (Anon 2014). Chauhan et al 2018) and are very good source of potassium, folic acid, vitamin E and low in sodium and cholesterol free (Than et al 2008)
