Leaf curl disease in chilli

The present study was aimed to identify spatial distribution of chilli leaf curl disease in chilli growing districts of Northern Karnataka. In order to support the studies of its epidemiology, collection of information related to cropping system, soil type and weather conditions which are pre-requisite to take final decision on sustainable disease management practices were also considered.

Chilli (Capsicum annuum L.) is an important crop grown worldwide for its use as spice and vegetable. Murda complex is the most destructive syndrome causing substantial economic losses in chilli production. Severe leaf curling, leaf distortion, vein banding, reduced leaf size and stunted growth are typical symptoms of the viral infection. Chilli is known to be infected by many viruses and association of Geminivirus with murda complex is under question as the complex disease doesn’t associate with whiteflies.

Seventy eight bird chilli genotypes were screened against leaf curl virus. Leaf curl disease scoring was done at 30th, 60th and 90th days after planting (DAP) based on visual symptoms of each observational plant. Initial screening was done under field conditions based on vulnerability index score (0 to 4 scale), disease reaction to each genotype was assigned based on Leaf pubescence which can be observed on the youngest mature leaves and it was classified as sparse (3), intermediate (5) and dense (7).

A field trial was conducted during Rabi, 2015-16 and Kharif, 2016 cropping seasons. An attempt was made to find out the cost effective management schedule to minimize the crop loss. Seven insecticides viz., Fipronil5% SC@800ml/ha, Indoxacarb 14.5% SC@400ml/ha, Acephate 75 SP@0.1%, Spinosad 45%SC@160ml/ha, Imidacloprid 17.8% SL@0.003%, Fenvalerate 20EC@500ml/ha and Carbofuran 3G@30Kg/ha were evaluated against vector activity to reduce the leaf curl disease incidence.

Chillies (Capsicum annuum) are an important commercial and export-oriented crop in India. Whitefly, Bemisia tabaci is a serious pest on chillies by destabilizing the plants through desapping plant juice and also transmitting chilli leaf curl disease (ChiLCD). Varietal resistance is the most economic, least complicated and environmental friendly approach for the control of insect pest damage. Fifteen accessions of Capsicum were screened against whitefly, under green house condition for categorization of the mechanism(s) of resistance.

Chilli leaf curl disease is a serious threat to summer crop of chilli in South India causing economic yield losses. Therefore, development of chilli hybrids having leaf curl tolerance and high yield is the present need in chilli growing regions. Seven high yielding lines were crosses with four resistant testers in line × tester mating design to produce 28 F1 hybrids. Highest heterosis over better parent was exhibited by the cross L6 × T4 for fruit length (74.71%), by L4 × T3 for fruit girth (37.58%), by L6 × T1 for fruits plant-1 (37.86%), by L1 × T2 for fruit weight (51.

Chilli is an economically important and widely cultivated crop of India. Chilli leaf curl disease complex is one of the major limiting factors in chilli production which is drastically decrease yield. The crop grown in Jharkhand usually suffers seriously from this disease. A field experiment on integration of insecticides as soil application with one and/or two sprayings each of other insecticides viz. Imidacloprid 17.8% SL @ 0.003%, Spinosad 45 % SC@160 ml/ha and neem products viz., Neem Seed Kernel extract (NSKE 5%) @ 5ml/ litre and Neem oil 0.
