Problematic Nursery Diseases

Damping off➡ “Is a soil-borne fungal disease that affects seeds and new seedlingsdamping off usually refers to the rotting of stem and root tissues at and below the soil surface. In most cases, infected plants will germinate and come up fine, but within a few days they become water-soaked and mushy, fall over at the base and die” (Planet Natural Research Center, 2018). In order to get rid of these, it’s important to treat the nursery bed either by soil solarization, formalin solution or formalin dust or fungicides like thiram or captan. In some cases you can purchase the seeds are pre-treated. If the disease appears after seedling emergence, then drench the nursery beds with 0.1% solution of brassicol or 0.7% captan or thiram after germination. In some case it might be better to remove and bury the affected seedlings from the beds otherwise you may end up spreading the disease.  The disease can be controlled to some extent by applying treated sand, soil and farm yard manure mixture up to the level from where the seedlings are falling➡Raising of virus free seedlings Leaf curl is a white fly transmitted viral disease, infestation starts from seedling stage and continue till harvest of the crop.
