“…En el número de flores por planta se obtienen diferencias significativas (p=0.01453) con más de 12 flores por planta con la aplicación de 300 mg ha -1 , llegando a valores de 34.0 en la variedad Claudia y 34.06 en Amalia, sin diferencias estadísticas entre ellas. Resultados similares, se reportaron recientemente en el cultivo del tomate aplicando (Reyes-Pérez et al, 2020). Figura 2.…”

Se estudió el efecto del QuitoMax® en el comportamiento de plantas de tomate de las variedades Claudia y Amalia en condiciones estrés salino. El experimento se desarrolló en el municipio Cauto Cristo provincia de Granma en el período de octubre de 2017 a marzo de 2018, en un suelo clasificado como salino sódico (CE 4 dS m-1). El diseño experimental utilizado fue de bloques al azar, con arreglo factorial, replicando cuatro veces cada variante. Se aplicó el bioestimulante a los 12 días después del trasplante (DDT) a razón de 300 y 400 mg ha-1 y el control (cero aplicación). Fueron evaluados, a los 45 DDT, la altura de la planta, la longitud de la raíz, el número de frutos, el número de racimos por plantas, el diámetro ecuatorial, el diámetro polar y el rendimiento. La aplicación del bioestimulante QuitoMax® incrementa el número de racimos por planta y la masa de los frutos del tomate en condiciones de salinidad comparados con el control. Se incrementaron los rendimientos agrícolas en un 43% y 76%, así como, los beneficios económicos en 1653.93 $ ha-1 y en 3418.08 $ ha-1 respecto al control, para las cultivares Amalia y Claudia, respectivamente, cultivadas en condiciones de salinidad. Los mejores resultados se obtuvieron al aplicar la dosis de 300 mg ha-1 de QuitoMax®.

“…In chili bell pepper plants, it stimulates germination, seedling emergence, and increases height, stem diameter, biomass and yield compared to controls [45]. Similarly, Reyes-Perez et al [46] mentioned that in tomatoes, germination, development and production increased due to the fact that chitosan increases photosynthesis and chlorophyll production, helps in stomatal closure, which makes water use more efficient, and its decomposition can produce ammonium, which is used by the plant. The results found in the present study strengthen the hypothesis that the application of chitosan is an organic alternative to the use of synthetic fungicides for the control of powdery mildew caused by L. taurica in jalapeño pepper.…”

One of the phytopathogens that cause severe damage to jalapeño pepper is Leveillula taurica (Lév.) Arnaud, the causative agent of powdery mildew. Synthetic fungicides are currently employed for its control, contributing to adverse effects on human health and the environment. The main objective of this research was to identify the causal agent of powdery mildew and assess the efficacy of chitosan in powdery mildew control on jalapeño pepper. The following treatments were evaluated in laboratory and greenhouse conditions: T1 = 0.0125% chitosan, T2 = 0.0025% chitosan, T3 = 0.05% chitosan, T4 = 0.1% chitosan, T5 = 0.2% chitosan, T6 = tebuconazole 25% (1.8 mL/L water), and T7 = control (water). Symptomatology results indicated that L. taurica is indeed the causative agent of powdery mildew. Treatments T4 and T5 exhibited the lowest percentages of incidences and severity, hence achieving higher control efficacy in the laboratory (57.70 ± 3.85 and 65.39 ± 3.85) and greenhouse (56.67 ± 4.08 and 70 ± 8.16%) compared to T6 (control efficacy, 38.46 ± 0.00% in the laboratory and 50 ± 0.00% in the greenhouse). The chitosan derived from shrimp had a significant impact on the cell walls of L. taurica spores and mycelium. Consequently, chitosan emerges as a viable organic alternative to fungicides for controlling powdery mildew in jalapeño pepper.

“…This product has shown stimulating effects on plant growth, including grain and tuber species (Falcón Rodríguez et al, 2021). Its use stimulates initial seed germination, flowering and fruit filling (Reyes-Pérez et al, 2020). QuitoMax ® has also been used in tomato and has caused an acceleration of plant metabolism and an increase of 15% in yield under saline soil (Avila-Amador et al, 2022).…”

Salinity stress severely restricts plant nutrition and hinders biochemical and physiological processes crucial for growth. In several crop systems bioactive products which confer growth promotion, are applied as a sustainable alternative for contributing to food security. The aim of this work was to evaluate the biochemical contribution of QuitoMax® to hormonal and enzymatic metabolism in tomato under saline stress. Three treatments were applied: saline without QuitoMax®, nonsaline + QuitoMax® and saline + QuitoMax®. A tolerant (Amalia) and a susceptible (Claudia) tomato variety were used as experimental models. The normalized difference vegetation index (NDVI) was measured as a morphological variable, and peroxidase (POD), glutamine synthetase (GS) and nitrate reductase (NR) enzyme activities were determined. Gibberellic (GA) and abscisic acid (ABA) concentrations were also determined. Due to the effects of QuitoMax®, the plants maintained high NDVI values even under saline conditions. A decrease in POD and GS activity and an increase in NR activity were also found. The GA concentration in the leaves was higher in the tolerant variety when QuitoMax® was applied than in the saline treatment but lower in the susceptible variety. The opposite behavior was found when the ABA concentration was quantified. This study demonstrates the protective action of QuitoMax® under salinity stress on tomato crops in both tolerant and susceptible varieties. In crux, QuitoMax® can be opted as a shotgun approach to tackle salinity in tomato.
