- the present invention also comprises seeds coated or treated with or containing a compound of formula (I).
- coated or treated with and/or containing generally signifies that the active ingredient is for the most part on the surface of the seed at the time of application, although a greater or lesser part of the ingredient may penetrate into the seed material, depending on the method of application.
- the seed product When the said seed product is (re)planted, it may absorb the active ingredient.
- the present invention makes available a plant propagation material adhered thereto with a compound of formula (I). Further, it is hereby made available, a composition comprising a plant propagation material treated with a compound of formula (I).
- Seed treatment comprises all suitable seed treatment techniques known in the art, such as seed dressing, seed coating, seed dusting, seed soaking and seed pelleting.
- the seed treatment application of the compound formula (I), which is a preferred application method, can be carried out by any known methods, such as spraying or by dusting the seeds before sowing or during the sowing/planting of the seeds.
- Table 1 provides compounds of formula (I)
- the compounds of formula (I) shows a fungicidal activity with respect to diseases caused by phytopathogenic fungi in particular rust disease pathogens such as Phakopsora pachyrhizi and Puccinia triticina which attack on important agricultural crops such as soybean and wheat crop rspectively.
- rust disease pathogens such as Phakopsora pachyrhizi and Puccinia triticina which attack on important agricultural crops such as soybean and wheat crop rspectively.
- Example A Phakopsora pachyrhizi test in Soybean Compounds were dissolved in 2% dimethyl sulfoxide/ acetone and then mixed with water to the calibrated spray volume of 50 mL and poured into the spray bottles for further applications.
- a visual assessment of compound’s performance was carried out by rating the disease severity (0- 100% scale) on treated plants on 3, 7, 10 and 15 days after application. Efficacy (% control) of the compounds was calculated by comparing the disease rating in the treatment with the one of the untreated control. The sprayed plants were also assessed for compound’s plant compatibility by recording symptoms like necrosis, chlorosis and stunting.
- Example B Puccinia graminis test in Wheat
- a visual assessment of compound’s performance was carried by rating the disease severity (0-100% scale) on treated plants on 3, 7, 10 and 15 days after application. Efficacy (% control) of the compounds was calculated by comparing the disease rating in the treatment with untreated control. The spyayed plants were also assessed for compound’s phytotoxic effects by recording symptoms like necrosis, chlorosis and stunting.
