Fusarium oxysporum f. Sp lycopersici is the causal organism that causes wilt disease in tomato all over the world. The antifungal activity of aqueous extract of neem leaf (5%), ginger bulb (5%), Lantana camara (5%), Trichoderma harzianum (5%), carbendazim (0.01%) and combination of carbendazim+T. harzianum (0.01+5%) was investigated against Fusarium oxysporum f. sp lycopersici in vitro.The least growth of pathogen was recorded in Carbendazim (treated control) (94.00) followed by Neem leaf (35.20) followed by Lantana camara (31.11), ginger bulb (26.

Studies were undertaken to evaluate the plant extracts, fungicides and bio-agents against early blight disease of tomato caused by Alternaria solani under in vitro and vivo conditions. Among the four evaluated plant extracts against A. solani, neem leaf extract at 15% (w/v) was found to be most effective in inhibiting the mycelial growth of the pathogen with inhibition of 52.36 per cent, followed by combination of garlic clove and green chilli extract with the inhibition of 50.42 per cent.

Early blight is potentially destructive disease in tomato occurring on the oldest leaves as small, brownish which are due to foliar blight disease and it was caused by a foliar fungal pathogen Alternaria solani. The disease causes considerable yield as well as post-harvest losses. A. solani produced blackish, fluffy mycelium with septate, beaked conidia on PDA Eight plant extracts and four biocontrol agents were evaluated following poison food technique and dual culture.

Tomato (Solanum lycopersicum L.) is the third most important crop in India that suffers from various biotic and abiotic stresses. Among the biotic stresses early blight caused by Alternaria solani [(Ell. and Mart.) Jones and Grout] is one of the most destructive diseases of tomato which leads losses up to 78 per cent.

The tomato (var. sumberson) is highly susceptible to diseases caused by microorganisms as well as pest infestations; as a result serious loss is caused thereof in the production of those crops. On the background of these facts, the research was focused on controlling the diseases through the selected treatments with the objectives of evaluating the efficacy of Lantana camara extract, Balanites extract and their combinations to assess on controlling the pest/disease incidence and severity in tomato field conducted in Hamelmalo Agricultural College.

Weed is a plant growing where it is not desired so weeds are ubiquitous. The vegetable fields are usually infested by a wide spectrum of broad and grassy weeds. Weeds compete with the crops for water, soil, nutrients, light, space and crop yields are significantly reduced as reported by several studies. The vegetable as well as agricultural crops are infested with a variety of weeds. Out of over 800 weeds documented in India, 80 are considered as serious and nearly 200 as major weeds. They also harbour many insect-pests and microorganisms.

The study was conducted in the department of Plant Pathology SHUATS Allahabad (2014) to investigate mycoparasitism inhibitory effects of Trichoderma spp, Pseudomonas sp, neem leaves extract and carbendazim on the growth of the Fusarium oxysporum f.sp. lycopersici which causes wilt of tomato in-vitro, Trichoderma harzianum, Trichoderma viride, Pseudomonas fluoresens were used @ 2% (dual culture technique) and carbendazim @0.1gm and Neem leaves extract in the ratio of 1:1(poison technique). Among all Trichoderma viride was the best inhibitor of test pathogen (87.

Indian soils are rich in microbial diversity, especially fluorescent pseudomonads (FPs) have drawn much attention worldwide because of their plant growth promotion ability by the production of plant growth promoting substance like Indole acetic acid (IAA). In this context, the present study explored for optimization and characterization of IAA production by our isolate Pseudomonas sp VSMKU 4050. The maximum IAA production was observed in King’s B broth (KBB) supplemented with 0.7% L – tryptophan.

The present study was carried out to find the integrated management of early blight of tomato (Lycopersicon esculentum Mill.) caused by Alternaria solani. Tomato (Lycopersicon esculentum Mill.) is an important vegetable crop which is grown all over the world. Early blight of tomato, caused by Alternaria solani is one of the most important diseases in tomato. Two fungicides i.e. Mancozeb 75 WP and Hexaconazole 5 EC at different concentrations (0.1%, 0.2% and 0.3%), two bio-agents viz., Trichoderma harzianum and T. koningii and two botanicals i.e.

Management of bacterial wilt is very difficult as there are no efficient curative chemicals. Carica papaya leaf extract was evaluated their antimicrobial activity against Ralstonia solanacearum. The zone of inhibitions showed against ten R. solanacearum at range of 5.96mm to 15mm of different solvent extracts like aqueous, ethanol, ethyl acetate, hexane, and chloroform.

With respect to the sampling of tomato it occurred at the beginning, on the highest peak and at the end of the production stage of tomato. For each sampling unit a zigzag path by the crop was followed, harvesting a tomato every three places along the zig-zag, and then based on a quartering system, obtaining a sample of 1 kg per plot.
