“…The incidence of rot oscillated around 47 to 79 % in the treatments, being TS+TA the most effective, increasing plant health in 53 % as compared to the witness condition which presented the highest incidence (Figure 1). Similar results were previously reported by Chandra et al (2008) who pointed out that with the application of antagonistic microorganisms such as T. harzianum, the incidence was reduced by more than 50 %. Another study by Ferrigo et al (2014) Infection of maize by F. verticillioides can occur through several routes, the most commonly reported method for infection of the grain is through airborne conidia that infect the stigmas, and thereafter the invasion of the stigmas, the fungus infects the seeds (Sartori et al, 2015).…”

To La inoculación mediante aspersión se llevó a cabo cuando habían emergido más del 50 % de flores femeninas, en la etapa R1 se realizaron aplicaciones dirigidas a los estigmas en tres oportunidades, a una concentración de 1x10 9 conidios/ mL repitiéndose cada tercer día, se suspendieron cuando la población se había uniformizado alrededor del 95 % de floración.…”

Las enfermedades ocasionadas por hongos son responsables de la mayoría de las pérdidas que afectan a las plantas. El maíz está expuesto a un sin número de patógenos a lo largo de su ciclo fonológico, entre los que destacan Fusarium, Ustilago, Aspergillus, Penicillium, etc. Algunos de éstos géneros producen sustancias tóxicas denominadas micotoxinas, las cuales representan un elevado riesgo para la salud humana y la de los animales que las consumen. El objetivo de este estudio fue evaluar la eficacia de tres cepas de Trichoderma para el control de pudrición de mazorca en cuatro genotipos de maíz, el experimento se estableció bajo condiciones de temporal e infección natural de F. verticillioides, se sembraron cuatro genotipos de maíz inoculados y sin inocular con Trichoderma spp, se evaluaron tres tratamientos distintos como es el tratamiento a semilla, aplicación mediante aspersión y la aplicación de las dos evaluadas de manera conjunta. Para determinan el efecto de biocontrol se determinó la incidencia de pudrición de mazorca y la severidad de la enfermedad. La severidad de la enfermedad se comportó baja en los tres tratamientos, el tratamiento a semilla más aplicación mediante aspersión evaluadas juntas presentó la severidad más baja comparado con el testigo. Las tres especies de Trichoderma redujeron la incidencia y severidad de la enfermedad en las tres técnicas utilizadas, T. harzianum fue la cepa que controló significativamente (P<0.0001) la enfermedad, además se obtuvo arriba de 70% de efectividad en todos los tratamientos.

“…Most of the earlier studies were restricted to greenhouse conditions while field experiments were performed solely for management of one mycotoxigenic fungus and its respective toxic metabolite (Nayaka et al, 2009;Nayaka et al, 2010;Sartori et al, 2013). Our aim was to manage multiple seed-borne mycotoxigenic fungi and their respective toxins under field conditions.…”

“…The most effective treatments were bagasse + T. harzianum (10 %), bio priming and bagasse + T. harzianum (5 %); they reduced Fusarium root rot by 73.9, 60.8 and 56.5 %, Rhizoctonia root rot by 78.6, 75, 71.4 % and M. phaseolinae charcoal rot by 70.8, 62.5 and 62.5 %, respectively. Nayaka et al (2010) attempted the use of T. harzianum as a seed treatment for controlling maize ear rot and managing fumonisin (synthesized by Fusarium verticillioides) accumulation in maize seeds. Seed treatments with T. harzianum improve seed germination and emergence, vigour index, plant height, yield and 1,000 seed weight of maize.…”

Seed priming is basically a physiological seed quality enhancement method which offers a hydration treatment that allows controlled imbibition and induction of the pre-germinative metabolism (activation), but radicle emergence is prevented. The beneficial effects of this technology are greater cellular membrane integrity, counter action of lipid peroxidation, antipathogenic effects, repair of biochemical lesions by the cellular enzymatic repair system and the metabolic removal of toxic substances. Disease is the disorder of the structure or function of a particular system, caused mainly with the aid of fungi, bacteria, viruses and nematodes. Wilt, blight, blast, rust, canker, decay, root diseases, etc. represent the common diseases of plants that cause a reduction in their yield. To get rid of plant diseases a number of fungicides, bactericides, etc. are in use, which impose their residual effects on the users of the plant parts. Consequently, a number of hazardous effects are also noted in human beings. To avoid this kind of hazardous effects on mankind, originated from the residual effects of different kinds of pesticide, an alternative measure must be taken into consideration. In this respect, different kinds of seed priming like hydro-priming, bio priming, osmo-priming, matrix priming and halo-priming can be adopted. Collar rot ( Sclerotium rolfsii) in chickpea, yellow mosaic virus of mung bean and downy mildew of pearl millet are found to decrease with the use of hydro-primed seeds whereas the use of Trichoderma in the form of bio priming has controlled the cowpea root rot pathogens. Salicylic acid alone or in combination with magnesium nitrate (Mg(NO 3 ) 2 ) induced resistance in groundnut and mustard plants against Alternaria alternate and Alternaria brassicae. Hence, the review frames a norm to work out the effects of seed priming towards the pathogen-related defence mechanism because seed-priming technology offers a number of benefits and helps to minimize pollution in different ways.
