“…The genotypic response to disease revealed that cultivars CH-121 and Chilli-900-F1 showed moderately resistant, Diamond CH-121 and Red Wing susceptible, and SAYBAN and AAHP-1 highly susceptible responses. Parey et al (2013) conducted a similar study, stating that the goal of eco-friendly management of chili leaf spot was to identify primary resistant sources against the pathogens. A. alternata and Aspergillus flavus were found to be linked with the disease in samples of chili leaves obtained from various places.…”

Chili (Capsicum annum L.) is a widely grown vegetable in tropical and subtropical areas that is attacked by a diverse range of bacterial and fungal pathogens, causing severe yield and quality losses. Alternaria leaf spot, caused by Alternaria alternata, is the major fungal disease of chili that deteriorates the vitality of the crop. The objective of the current research is to identify the most effective nutrient combination and fungicide against Alternaria leaf spot disease and to evaluate resistant sources. The current research was conducted using six varieties (CH-121, Chilli-900 F1, Red Wing, SAYBAN, AAHP-1, and Diamond CH-121) collected from Ayub Agricultural Research Institute, Faisalabad, Pakistan. Seeds were sown in the Plant Pathology field area, University of Agriculture, Faisalabad, to screen against leaf spot disease. The effect of different fungicides and nutrients to overcome chili leaf spot was studied, and three treatment combinations were prepared: (ZnSO4 (ZS) + MnSO4 (MS) + boric acid (BA) + Topsin M), (ZS + MS + BA + Mancozeb), and (ZS + MS + BA + Vitavax). Among these, the combination of (ZS + MS + BA + Vitavax) was the most effective against leaf spot disease. Minimum disease severity was observed with ZS + MS + BA + Vitavax in CH-121 (15.00), while maximum disease severity was observed with the control in Red Wing (93.67). Environmental data were collected and statistically analyzed. There was a significant (p 0.05) but positive correlation between maximum temperature, minimum temperature, wind speed, rainfall, and disease severity. There was a negative correlation between relative humidity and disease severity. In conclusion, micronutrients were found to enhance Alternaria leaf spot tolerance in chili plants, providing a cost-effective and easily obtainable solution. The combined use of nutrients and fungicide is effective in preventing the development of resistance in pathogens against fungicides.

“…Management of fruit rot (anthracnose) by adapting the integrated strategies like mechanical, chemical, biological would be suitable to minimize yield loss (Agrios 2005) [2] as the use of chemicals lead to the development of soil pollution and food poisoning. The use of biopesticides/ biocides are the foremost approach to get the better of these nasty effects (Priya Reddy et al 2019) [15] . Application of the natural algal extracts are nowadays more applicable instead of synthetic fungicides in controlling plant pathogen due to their higher safety and relatively negligible impacts on the environment (Gatal et al 2011) [6] .…”

Marine macroalgae are rich sources of structurally novel and biologically active metabolites that could be used in biological control in the agricultural field. Many bioactive compounds have been identified from marine algae with antimicrobial activity, some of these compounds are sterols, terpenoids, polysaccharides, peptides, proteins, vitamins, acrylic acid, terpenes, chlorophyllides, phenols, heterocyclic compounds, halogenated ketones and alkanes and cyclic polysulphides. The present study is conducted to estimate the antimicrobial potential of extracts of fifteen marine macroalgae. Among 15 seaweed Padina gymnospora at 30% highest concentration was found to be the best in the reduction of mycelial growth and increased the germination percentage under in vitro condition. Application of P. gymnospora, in in vivo in the chilli pot experiment significantly decreased the percent of fruit rot in fruit in 43.43, 60.52 and 71.01% on 80,100 and 120 DAT respectively. Moreover, P. gymnospora enhanced growth performance of chilli plant in terms of shoot length and root length. Interestingly, the seed and air free pathogen treated with P. gymnospora showed significant increase flower compared to the control treatment besides increasing of fruit fresh weights. A considerable antimicrobial activity and the presence of phyto-chemical naphthalene indicated that P. gymnospora can be considered as a source of biocide and a biostimulant against anthracnose plant disease.
