“…Other researchers have demonstrated that smoke-water can protect the seeds and seedlings of many plant species in the southwest of Western Australia against microbial attack, resulting in higher seedling survival and healthier seedlings for transplanting (Roche et al, 1997). A greater percentage of healthy seedlings would be an asset to commercial transplant production (Bennett et al, 1992).…”

The antifungal efficacy of smoke-water on damping-off caused by Pythium sp. was evaluated both in vitro and in vivo. Smoke-water was generated by burning plant material and bubbling the smoke through water; its effect on the morphology of Pythium sp. was investigated by scanning electron microscope (SEM). Mycelia growth and oospore production of the fungus were significantly inhibited when cultured on water agar amended with smoke-water at 0%, 0.5%, 1%, 1.5%, 2%, 2.5%, 3%, 3.5%, 4%, 4.5%, or 5%. In growth chamber experiments with potted seedlings growing in peatmoss, papaya plants treated with smoke-water exhibited reduced symptoms of damping-off when compared with control plants treated with water. Furthermore, the pots treated with 1.5% or higher smoke-water did not show any symptoms of damping-off disease. Plant height significantly increased with treatment by higher concentrations of smoke-water. Maximum plant height was observed with treatment of 1% smoke-water or higher concentrations. One day after smoke-water application, SEM observations of the Pythium sp. revealed loss of structural integrity, abnormal degradation, deformation, abnormal lysis, cytoplasmic leakage, and hyphal slimming. This study showed that the addition of smoke-water to soil exerted significant disease suppression against Pythium sp., leading to improved growth of papaya seedlings.

A smoke-derived butenolide, 3-methyl-2H-furo[2,3-c]pyran-2-one, has previously been shown to improve seedling vigour. The aim of this study is to examine the effect of hydropriming and butenolide priming treatments on seedling emergence and growth under different sowing depths at 20 and 258C in two melon (Cucumis melo L.) seed lots of high and low quality. Seeds are subjected to hydropriming (21 h at 258C) and butenolide priming (10 (7 M, 21 h at 258C) and sown at a depth of 4 or 8 cm in peat moss (field capacity, 64% water by mass). In general, seedlings from butenolide-primed and hydroprimed seeds are superior to those of the control. At 208C, the effect of butenolide priming is more pronounced than that of hydropriming and the control, particularly for the seeds sown at a depth of 8 cm. Butenolide priming has a 'repairinducing' effect and enhances the low-quality seeds more than those of the high-quality seed lot, an effect which is more obvious at 208C than 258C. It can be concluded that butenolide priming may be a useful tool to enhance melon seedling performance under low temperature sowing conditions.

“…Coating seed with polymers, fungicides, and insecticides may enhance seedling establishment and may prevent stand failures. Polymer coatings of seed improve physical properties of the seed and provide protection from biologiciil enemies of the seed (Bennett et a!., 1992). Such beneticial effects of polymer coatitig of winter canola seed, with or without fungicides, for the southeastern USA, have not been explored.…”

Increased stand establishment from polymer-coated seed has been reported in some crops, including spring type canola {Brassica napus L.), however, effects of polymers on winter canola have not been evaluated. The objectives of this research were to evaluate effects of three polymers [CelGard (CP), Spectrum 511 (SP), and DiscoClear (DC)], each at three concentrations (0.33%, 0.66%, and 0.99%), alone, with fungicide Helix, and Apron applied to seeds of two winter canola cultivars 'Jetton' and 'Abilene', which were planted at 1.9 cm and 3.8 cm depth in three soil types (sandy, silt, and clay loam). Treatments were distributed in a randomized complete-block design in each soil. Polymer CelGard application on cv. 'Abilene' and DiscoClear on cv. 'Jetton' gave highest seedling establishment in all three soil types. Seeds of both the cultivars, when centricoated with Helix, along with polymer coating, gave higher seedling establishment (88.0% in cv. 'Abilene' and 85.0% in cv. 'Jetton') as compared to other respective polymer treatments without Helix. The seedling establishment was higher when coated seeds were planted at 1.9 cm depth than at 3.8 cm. From this research it was concluded that coating winter canola seeds with polymers increased seedling establishment and Gaganpreet Kaur and Udai R. Bishnoi are affiliated with the
