“…Seed treatments of oilseed rape ( Brassica napus L.) directed against the blackleg disease caused by L. maculans have shown that the rhizobacteria Serratia plymuthica Breed et al 1948 and P. chlororaphis can reduce disease severity by 71.6 and 54% respectively. However, with the application of these two rhizobacteria in combination, using the biopriming technique, the effectiveness of the combined treatment was not superior to that with S. plymuthica alone . In another study, a greater reduction in disease infestation under field conditions was provided by the combined treatments of S. plymuthica and Clonostachys rosea f. catenulata (J.C. Gilman & E.V.…”

Seed treatments to control seedborne fungal pathogens of vegetable crops

Vegetable crops are frequently infected by fungal pathogens, which can include seedborne fungi. In such cases, the pathogen is already present within or on the seed surface, and can thus cause seed rot and seedling damping-off. Treatment of vegetable seeds has been shown to prevent plant disease epidemics caused by seedborne fungal pathogens. Furthermore, seed treatments can be useful in reducing the amounts of pesticides required to manage a disease, because effective seed treatments can eliminate the need for foliar application of fungicides later in the season. Although the application of fungicides is almost always effective, their non-target environmental impact and the development of pathogen resistance have led to the search for alternative methods, especially in the past few years. Physical treatments that have already been used in the past and treatments with biopesticides, such as plant extracts, natural compounds and biocontrol agents, have proved to be effective in controlling seedborne pathogens. These have been applied alone or in combination, and they are widely used owing to their broad spectrum in terms of disease control and production yield. In this review, the effectiveness of different seed treatments against the main seedborne pathogens of some important vegetable crops is critically discussed.

Watermelon is an important summer crop in Palestine, for several decades filling the needs of local market and some Arab countries. The yield of watermelon decreased dramatically in recent years due to severe infections with the soil borne fungal pathogen Fusarium oxysporum f. sp. niveum (FON). Soil fumigation with methyl bromide was commonly applied by Palestinian farmers until it was recently legally banned. Different control mechanisms were not feasible to overcome problems caused by the disease resulting in decreased watermelon cultivation in Palestine for the past 30 years. In this work, we have experimentally shown that Pseudomonas fluorescens was efficient in controlling FON infection and allowing normal seedling growth of both the root and shoot systems. Field experiments are necessary to further confirm the efficacy of biocontrol application.

“…The experimental results have proven that the tested PGPF, promoted growth and induced systemic resistance (ISR) in sunflower plants against the downy mildew disease caused by P. halstedii, due to their growth-promoting and biocontrol abilities. Abuamsha et al (2012) observed that the efficacy of a seed treatment of oilseed rape (OSR) ( Brassica napus) with the rhizobacteria Serratia plymuthica (strain HRO-C48) and Pseudomonas chlororaphis (strain MA 342) applied alone or in combination against the blackleg disease caused by Leptosphaeria maculans was tested with different cultivars. Seeds were soaked in bacterial suspensions (bio-priming) to obtain log 10 6-7 CFU seed −1 .…”

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.
