“…Among different treatments, the lowest fresh weight of shoot was observed in T 1 treatment (145.8 g/plant) but it was statistically similar with T 2 treatment. It is interesting to noteworthy that present results are in harmony with the findings of [37] who illustrated significant increases in shoot fresh weights due to the application of vermicompost when compared with the plants treated with only chemical fertilizer.…”

Aims: Under the intensive agriculture system, it is crucial to maintain the soil fertility for the sustainability of crop production. Therefore, the study was conducted in the experimental field of the Department of Soil Science of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur to investigate the effect of different manures in combination with synthetic inorganic fertilizers on growth, yield and yield contributing characters of BARI Mistimorich 1 (Capsicum annuum L.), a variety of sweet pepper. Nutrient content of capsicum and soil fertility status were also assessed. Materials and Methods: The field trial was established following a randomized complete block design (RCBD) having four replicates. Treatments of the field trial included T1= 100% recommended dose of chemical fertilizers (RDCF), T2= 10t/ha cowdung (CD) + IPNS based chemical fertilizers (CF), T3=10t/ha poultry manure (PM) + IPNS based chemical fertilizers (CF) and T4= 10t/ha vermicompost (VC) + IPNS based chemical fertilizers (CF). Results: Experimental results reveal that application of organic manures in combination with chemical fertilizers produced significantly higher plant height, plant weight, number of branches per plant, number of flowers per plant, number of fruits per plant, fruit weight, fruit length, fruit diameter, total yield and nutrient content and uptake in sweet pepper. Organic manures (CD, PM and VC) in combination with chemical fertilizers ensured higher nutrient uptake when compared with the sole application of inorganic fertilizers. Among the treatments, vermicompost treated plots gave the higher yield of sweet pepper and improved the post-harvest soil nutrient status. Conclusion: Vermicompost was found to be suitable as substitute of other organic manures for the production of capsicum.

“…La secuenciación del ADN confirmó que la cepa aislada de las muestras a, b, and c). When the plants were inoculated with P. capcisi, differences were observed with the control plants (not inoculated), like in reports by Uribe-Lorio et al (2014) in their work with chili pepper plants. The control plants remained healthy throughout the experiment.…”

“…No se observaron diferencias significativas (α=0.05) entre los tres niveles de inóculo de P. capsici para las variables número de hojas marchitas, necrosis en la zona de transición entre el tallo y las raíces y marchitamiento de plantas de chayote (Figura 3 a, b y c). Cuando las plantas fueron inoculadas con P. capcisi, se observaron diferencias con respecto a las plantas testigo (no inoculadas), igual como lo reportan Uribe-Lorio et al (2014) en un trabajo realizado con plantas de chile. Las plantas testigos permanecieron sanas durante todo el experimento.…”

Se determinó la severidad de Phytophthora capsicien plantas de chayote y se propuso una escala de severidad, dada su reciente confirmación como agente causal de enfermedad. Se muestrearon plantas con síntomas de marchitez en dos huertos comerciales de chayote en Huatusco, Veracruz, México. El oomiceto aislado, a partir de frutos y tallos, fue caracterizado morfológica y molecularmente e identificado como P. capsici. Plantas de chayote desarrolladas en cámara de crecimiento fueron inoculadas con 1, 3 y 6 x 105 zoosporas 15 días después de la siembra. Se evaluaron la necrosis de la zona de transición entre el tallo y la raíz, el porcentaje de hojas marchitas y la marchitez de la planta. A los tres días después de la inoculación (ddi) se observó de 2.3 a 3.0 cm de longitud de la necrosis y 50 % de hojas marchitas. A los cinco ddi, la necrosis fue de 2.5 a 3.15 cm y 80 % de hojas marchitas. A los siete ddi, la necrosis fue de 2.67 a 3.3 cm con 100 % de hojas marchitas (planta muerta). Con base en los síntomas observados, se diseñó una escala de severidad para evaluar el avance del daño de P. capsicien plantas de chayote bajo condiciones controladas.

“…The manifestation of the first symptoms is the wilting of the leaves, preserving the color, and hanging from the petioles to the plant; at the root there is a soft, odorless rot, until it reaches its loss or detachment ( González-Chavira et al, 2009 ). At the base of the stem there is a brown stain that as the disease progresses becomes black, causing tissue necrosis and external injuries such as sunken cancers that gradually strangle the stem; the stems are kept upright with the hanging leaves, the nuts, and wrinkled ( González-Chavira et al, 2009 ; Uribe-Lorío et al, 2014 ).…”

Effect of Fragmented DNA From Plant Pathogens on the Protection Against Wilt and Root Rot of Capsicum annuum L. Plants

et al. 2021

Chili pepper (Capsicum annuum L.) production is affected by wilt and root rot, the most devastating disease caused by the pathogen complex of oomycete Phytophthora capsici Leon and the fungi Fusarium oxysporum Schlecht and Rhizoctonia solani Kühn, infecting roots, stems, leaves, and fruits. Fungicides are currently inefficient against this disease and have a high environmental impact. The use of elicitors is a sustainable alternative for inducing resistance to wilting and root rot. DNA fragments of an organism’s own origin (conspecific or self-DNA) have shown the ability to inhibit growth and activate defense mechanisms in some plant species. In this investigation, the effect of the fragmented DNA mixture of Phytophthora capsici L., Fusarium oxysporum S., and Rhizoctonia solani K. on the protection against wilt and root rot of Capsicum annuum L. plants was evaluated. Changes in plant performance, phenolics, and flavonoids contents, as well as gene expression involved in the production of defense metabolites after the fragmented and unfragmented DNA mixture in three concentrations (20, 60, and 100 μg mL–1) in chili peppers, were studied. The results obtained showed a decrease in plant height in 60 and 100 μg mL–1 concentrations in absence of pathogens. Moreover, the treatment with fragmented DNA 100 μg mL–1 showed significant increase in the content of phenolic compounds and total flavonoids as well as gene expression associated to plant defense in comparison with control plants. Interestingly, foliar application of DNA fragments of the pathogen complex to a concentration of 100 μg mL–1 caused a 40% decrease in the mortality of infected plants with the pathogens at 30 days post-inoculation compared with control plants inoculated with the pathogen complex but not sprayed with DNA fragments. These results suggested a perspective for application of fragmented DNA of these pathogens at the agricultural level in crop protection strategies to cope with wilt and root rot in Capsicum.
