  4. Chilli is often found affected by damping off disease in nursery stage. Owing to the great loss of the seedling an investigation was undertaken to manage the damping off disease of chilli. The experiment was conducted under in vitro Five treatments were taken up with four replications and data collected was analyzed using CRD

Damping off typically occurs when old seed is planted in cold, wet soil and is further increased by poor soil drainage. High humidity levels, rich potting soils and planting too deeply will also encourage its growth. Fungal spores live in the soil and are primarily a problem in seed beds An effective management of damping-off requires the deployment of a number of strategies, which can be classified into the following four major groups: (i) seed treatment to enhance germination and seedling vigor, (ii) deployment of resistant or tolerant cultivars to damping-off diseases, (iii) adoption of best cropping practices, and (iv) timely treatment interventions of seedlings with effective products (conventional pesticides as well as biopesticides and/or biocontrol agents)

Pseudomonas fluorescens 0.5% W.P. formulation applied as seed and furrow (soil application) in Chilli significantly reduced the damping off disease of chilli caused by P. aphanidermatum.

the management of damping off of tomato, chilli and cabbage vegetable crops. The results revealed that all the treatments significantly reduced the damping off incidence in nursery over untreated control. The pooled data indicated that per cent disease incidence was significantly lowest in all the treatments over the control The damping-off in control treatments was maximum and expected and it varied (Table 2) brinjal (57%), tomato (70%), Chilli (38%), cauliflower (44%) and cabbage (41). In various microbial, neem formulations and fungicidal treatment, damping-off disease was significantly reduced to the extent o Evaluation of plant products against chilli damping-off has been previously attempted under both greenhouse and pot culture conditions (Kurucheve and Padmavathi, 1998). However, no attempts have been made for the management of chilli damping-off by using the combination of both plant products and biocontrol agents Chilli (Capsicum annuum L.) is one of the most economically important vegetable crops in the world. Among different biotic constraints, anthracnose disease is the major limiting factor affecting yield and production of chilli crop. Different symptoms associated with disease are fruit rot, leaf spots, dieback on stem, seedling blight, or damping off

Chilli crop is attacked by more than dozen diseases of fungal, bacterial and viral nature leading to great loss to cultivators. Among those diseases, damping off of chilli incited by Pythium spp. is responsible for 90 per cent mortality either as pre or post-emergence damping off in nurseries and field conditions Damping-off can be minimized by providing good drainage (raised beds, leveled fields), careful irrigation, planting when soil and air temperatures are favorable for rapid seedling emergence, proper depth and spacing of planting, seed treatments, and drenches of soil fungicides.

Chilli Pests and Diseases and their control methods:. The following is about Chilli Pests and Diseases, Symptoms, Control Measures. Diseases in chilli plants are less common, but often more dangerous to plants. Diseases mainly affected due to Bacteria, Fungi, Virus, and Other sources. The Disease mainly affects yields by reducing the photosynthetic area in the early stages and infestation on. Damping off: This is a fungal disease and can happen nursery beds before the seedling emerges from the soil which can kill the seedlings and may cause seed rot. This can be prevented or controlled by providing good drainage beds and sterilizing the soil by burning trash in the surface. The capsicum seedlings may be protected by spraying with 0.5 to 1.0 % Bordeaux mixture The pathogens that cause damping off can live in the soil, and outdoor garden soil can harbor all kinds of fungus spores. Start with clean pots. Even the small amount of soil clinging to plant pots is enough to provide a safe harbor for fungal spores. If reusing pots, sterilize in 1 part bleach to 9 parts water

Pythium aphanidermatum is a soil borne plant pathogen. Pythium is a genus in the class Oomycetes, which are also known as water molds.Oomycetes are not true fungi, as their cell walls are made of cellulose instead of chitin, they are diploid in their vegetative state, and they contain coenocytic hyphae (lacking crosswalls), called a protist. Also, they reproduce asexually with motile. Fungicide to Prevent Damping Off. The seeds and seedlings of turfgrass, fruits, vegetables and ornamental plants are potentially impacted by damping off or seed rot, caused by fungal pathogens The efficacy of 14 seed and drench treatments for control of soilborne damping-off pathogens in organic production of spinach was evaluated in a greenhouse study. The efficacy of each treatment was compared with nontreated seed and seed treated with a conventional fungicide for control of Fusarium o damping-off of seedlings is often associated with symptoms such as reduced growth, wa-ter soaking, wilting, black or brown discoloration, and root rot [20-22]. In more mature plants, water-soaked roots and lesions of stem at the soil line, stunted growth, and brown discoloration of roots are prevalent [23] Chilli plant diseases are less common but often far more dangerous to plants than other problems detailed on the site. Identify the problem with the guide below and find some tips on how to cure or when best to remove and destroy plants to prevent further infections. A tray of seedlings can suffer Damping Off at one end but avoid infection.

Treatment of seeds using Thiram 75 WS at the dose of 2.5 kg/g of seeds reduced the pre-emergence damping-off losses from 29.06% in untreated control to 6.52% in treatment and post-emergence damping-off losses from 59.12% in the untreated control to 16.15% in treatment conditions Pythium damping off of chilli (Capsicum annuum L.) is very common problem in fields and green houses, whereas the organism kills newly emerged seedlings.

Integrated management of damping-off diseases

Damping-off is primarily caused by fungi present in the growing medium. The fungi include species of Rhizoctonia, Pythium, Fusarium, Phytophthora, Sclerotinia, Sclerotium, Botrytis, and others.Germinating seed and seedlings, especially weak ones, are vulnerable to attack by these fungi during periods of unfavorable growing conditions Management Sanitation Good sanitation is the best way to manage Rhizoctonia damping-off in float systems and prevent sore shin in fields. Limiting the amount of initial fungal inoculum is the most important step to managing disease. New trays can eliminate the risk of carrying over inoculu Damping-off of chickpea is one of the critical concerns of producers raising organic chickpea. Little was known about the pathogens causing damping off in Montana prior to this research. To determine the organisms responsible for damping off, pathogens were isolated from chickpeas affected by damping off at three field sites and identified to.

There are several fungi which may cause damping off. These include Pythium, Rhizoctonia, Theleviaopsis, Fusarium spp. and many more. The identity of the culprit may seem unimportant, but if the problem persists, knowledge of the causal fungus may help one to know how to alter the environmental conditions or even find a product for management Published: May 1, 2011. Many growers try to plant warm season vegetables earlier to take advantage of high early season prices. Unfortunately, the chances of transplanting crops like tomatoes, peppers, and cucurbits into field conditions favorable to damping off is increased, even if using good practices like raised beds covered with plastic mulch and protected by floating row covers The pathogen was isolated from chilli seeds were sown thickly in pots under green house conditions. After sowing, the pots were kept under shade and watered daily to favour the incidence of damping-off diseases. After 14 days, seedlings showing damping-off symptom were collected and the pathogen was isolated by tissu lignified. Pre-emergence damping-off occurs when seeds are killed before germination or germinating seeds are killed prior to emergence from soil. Post-emergence damping-off occurs when the germinating seed has emerged from soil, but then dies (Figure 1). Figure 2. Rhizoctonia Figure 1. Post-emergence damping-off. Seedling Disease Pathogen Damping-off is a soil borne disease that can attack almost all young vegetable seedlings. Home gardeners often first notice that something is wrong when the very young seedlings have a constriction around the base of the stem, some of the seedlings have fallen over or there are small flying gnats around the base of the seedlings

Damping off is a soil-borne fungal disease that affects seedlings, causing the rotting of stem and root tissues at and below the soil surface of the young plants. The term is quite a general one, encompassing several disease-causing culprits, the most common of which are well-known fungal foes such as Rhizoctonia spp ., Fusarium spp . and. Pythium infection leads to damping-off in seedlings and crown and root rot of mature plants. In Canada, several Pythium species, including P. aphanidermatum, P. irregulare and P. ultimum, are known to cause damping-off and crown and root rot in greenhouse cucumber, pepper and tomato crops. There are no Pythium-resistant varieties available.
