How to treat seed rhizomes?
Seed rhizomes have to be treated before planting to control rhizome rot and other seed-borne diseases . Park (1937) reported the beneficial effect of seed treatment against Sclerotium rolfsii. Seed treatment by farmers in Kerala is done by dipping seed rhizome in cow dung emulsion ( Mirchandani, 1971) and another way is to smoke the seed rhizomes once or twice before storage ( Mirchandani, 1971 ). Hot water treatment of seed rhizomes at 48°C for 20 min before planting was also an effective seed treatment ( Colbran and Davies, 1969 ). The cut end of seeds is dipped for 10 min in benomyl 0.25% to prevent entry of pathogens ( Whiley, 1974 ). Treating the seed with formulations such as Agallol 0.5% for 3 min or wettable Ceresan 0.1% for 30 min or Coppersan 0.3% for 60 min ( CSIR, 1976 ), wettable Ceresan 0.25% ( Kannan and Nair, 1965 ), Dithane M 45 ( Mohanty et al., 1990) are recommended as seed treatments. Treating the rhizome in ethrel increased the growth and development of ginger ( Islam et al., 1978 ). A pre-plant soak application of Ethephon at 750 ppm with warm (51°C) water for 10 min has increased shoot number of ginger cultivars ( Furutani et al., 1985 ). Ra et al. (1989) have observed that the low temperature (5°C) treatment of seed rhizomes decreased plant weight and rhizome yield. Treating by steeping seed rhizomes in spore suspension of T. viride or T. hamatum was found effective against the pathogen P. aphanidermatum causing rot ( Bharadwaj et al., 1988 ). T. harzianum, T. aureoviride, G. virens, and T. viride treatments reduced rhizome rot caused by F. solani or P. myriotylum and significantly increased growth, development, and yield of ginger ( Ram et al., 2000 ). The cut rhizome pieces are dipped in fresh and clean plant ash to seal off the wounds ( Xizhen et al., 2005 ).
How to treat seedborne fungi?
They may be based on warm water (45 °C, 2 h), hot-water treatments (52 °C, 10 min) and/or hot air/steam treatments. Warm or hot water treatments were shown to prevent/reduce Fusarium disease development effectively ( Jahn, 2002 ), often showing similar efficiency to chemical seed dressing ( Winter et al., 1997; Forsberg et al., 2005 ). On the other hand, thermal treatments based on hot air and hot steam have not yet found their way into agricultural practice ( Jahn, 2002 ).
What is the purpose of a seed dressing?
(1996) and Schauder (2003) as a direct method to improve seed quality and remove/reduce seedborne disease inocula. ‘Electron’ seed dressing effectively removed common bunt spores ( Tilletia caries) and reduced bunt levels compared to untreated seeds in field trials. However, its efficacy against M. nivale has not, as yet, been confirmed. Since this technique has potentially negative effects on germination rates of seed, it is limited to surface treatments ( Jahn, 2002; Jahn et al., 2005 ).
How does SA affect wheat seed?
Hayat et al. [ 50] advocated a positive effect of SA-assisted presowing seed treatment at the rate of 10 −5 M on total fresh and dry mass per seedling in wheat. Few other studies demonstrated enhanced germination percentage and rate, root-to-shoot ratio, dry and fresh weight, plant growth, which in turn increased the crop yield under both normal and salt stressed condition after presowing seed treatment with SA at optimal concentrations [ 33, 51, 52 ]. Aldesuquy et al. [ 53] showed that SA priming may reduce both size and numbers of stomata in wheat, while decreasing rate of transpiration under salt stress conditions, which reduces its harmful effects on seed growth. Furthermore, Kaydan et al. [ 54] demonstrated that application of SA as presowing seed treatment in wheat may enhance the seedling emergence by means of increasing leaf solute potential, root and shoot dry weight, root dry mass, K + /Na + ratio, chlorophyll a, b, and carotenoid content in salinity stress.
What is the most effective method of application of Trichoderma?
Seed treatment or coating is the most effective method of application of Trichoderma into an agricultural system ( Mathre et al., 1999 ). Trichoderma is delivered in the infection court (surface of seed coat) as protectant at planting. This method of delivery should limit growth of competitive microflora and provide conducive growth for the biocontrol agent. Seed treatment using seed dressing formulation, Pusa 5SD has been proven more effective than soil application formulations PusaBiogranule 6 (PBG 6) and PusaBiopellet 16G (PBP 16G) in managing wet root rot of mungbean caused by R. solani ( Dubey et al., 2011 ).
What is the best treatment for T. caries spores?

What was the first seed treatment?
Some of the first recorded seed treatments are the use of sap from onion (Allium spp) and extract of cypress in the Egyptian and Roman periods. Salt water treatments have been used since the mid-1600s and the first copper products were introduced in the mid-1700s. Other key milestones were the introduction of arsenic, used from 1740 until 1808 and the introduction of mercury, used from 1915 until 1982. Until the 1960s seed treatments had been only surface disinfectants and protectants. The first systemic fungicide product was launched in 1968. This systemic fungicide had not only seed surface activity but also moved into the plants protecting the young seedlings from airborne pathogens. Since the 1990s the crop protection and seed industries have developed and adopted new classes of fungicide, insecticide, and nematicide chemistry, expanding pest control while reducing user and environmental impact. The seed and seed treatments industries have a long history of partnership and dedication in providing growers with high quality seed. Today the seed must be as pest- and disease-free as possible and the treatment must provide protection against pests and diseases during germination, emergence and growth of the plant.

Reduced Active Ingredient Loading into the Environment.
Why is breeding important for agriculture?
Breeding is an excellent tool to build resistances against pests and diseases in the plants. However, breeding alone does not address all of the agronomic challenges, therefore crop protection products are often needed and used for good crop management. These crop protection products can be applied during the growth of the crop but can also be added to the seed as a seed treatment. Seed treatments have played and are still playing a significant role in the history of mankind, in staving off hunger and starvation by improving the establishment of healthy crops.
