Common rust of maize caused by Puccinia sorghi Schw. is an important disease which results in heavy yield loss. Spore germination was maximum within 24 hr at temperature in the range of 20-30°C. Differential spray schedule with Hexaconazole 0.1% revealed that, rust index was least in T5, i.e., five sprays of Hexaconazole (30.25%) and the disease was completely free with T6, i.e., six sprays of Hexaconazole. The disease development started on 30 days (22.34% PDI) and increased progressively up to 90 days (88.56% PDI) and later on became stable. Among the inbred lines MI-12 and Indimyt-345 are highly resistant to common rust of maize and among hybrids viz., NK-6240, NK-61, NK-7305, CP-808, GK-3090, 30R77, CP-818, C-1945, JKMH-502, PAC-740, NK-121, Pro-311, DK-984 and Swarna registered resistant reaction under artificial inoculated field condition. A systemic fungicide, Tebuconazole 250 EC and nonsystemic fungicide, Mancozeb + Phyton and botanical product, Neemazol F 5% were most effective which resulted in less per cent germination of uredospore. The ITK’s viz; Jeevamrutha @ 20 per cent concentration caused significantly less per cent germination (22.69%).

Howeever, carbendazim was found most effective followed by Mancozeb, carbendazim + Mancozeb, Propiconazole, Hexaconazole, Difeconazole, Propineb, Focetyl AL while fungicide chlorothalonil was found comparatively least effective against the test pathogen.All the nine botanicals / plant extracts tested at various concentrations significantly inhibited the mycelia growth of C.truncatum. However, Garlic found most effective followed by Tulsi, Onion, Giner, Neem, Parthenium, Bougenvilia and Eucalyptus. While plant extract of Mehandi was found least effective against test pathogen.5. All the four bioagents tested at various concentrations significantly inhibited the mycelia growth of C. trunchatum. However, T. viride was found most effective followed by T. hamatum

All crop plants produced have the potential to become diseased under certain conditions. Diseases of crops can affect yield and/or quality of the harvested commodity. This can impact profitability and increase the risks of farming. A plant is diseased when it is affected by some agent that interferes with its normal development. Some disorders are caused by noninfectious factors, such as temperature extremes or nutrient deficiencies. However, this publication focuses on diseases caused by infectious microorganisms. Diseased plants exhibit a variety of symptoms. These can include stunting, yellowing, wilting, twisting, reddening, browning, blighting, root rot, fruit rot, or other abnormalities. Accurate diagnosis is important in order to effectively control a plant disease. Diagnosis is an art as well as a science, andexperience is important. Until a disease is properly diagnosed, a farmer may waste time and money trying to correct a problem with an unknown cause. Once a disease is diagnosed, appropriate control practices can be selected. Your local Extension agent can provide information on identification and management of crop diseases.

System of Rice Intensification (SRI) is under evaluation in 29 countries at present, where it has been shown that yields can be enhanced by suitably modifying certain management practices such as controlled supply of water, planting of younger seedlings and providing wider spacing. This method of cultivation is said to promote greater root growth and higher soil biological activity in the rhizosphere. The benefits of SRI include increased yield (20-25%), a reduction in seed requirement (75%), water saving (45-50%), strong and profuse root system and tillering resulting in lodging resistance, improving soil health, reduction in pests, diseases, grain shattering and unfilled grains. The System of Rice Intensification improves yields with less water, less seed, and less chemical inputs than most conventional methods of rice cultivation. This means that the returns on inputs are higher, making the method potentially more profitable than most of the traditional methods.

As a component of biology, Plant Pathology enjoyed a prestigious position and its applied aspects; plant disease management was an integral part of agroecosystem management. In the era of globalization, our country is progressing very fast in agricultural sector by developing innovative techniques and augumenting increased production and productivity. In recent years the disease problems in many crop plants attracted the attentions of the scientists to device newer techniques in an integrated approach. The practical manual on “Introductory Microbiology” is prepared by integrating all the available approaches viz. staining, culturing on media, shape and size of bacteria etc. This book will be useful not only to the students and researchers in the field of plant pathology, but also to the extension functionaries who concerned with disease management.

Agriculture has been facing the destructive activities of numerous non insect pests from time immemorial, leading to radical decrease in yields. Pests are constantly being introduced to new areas either naturally or accidentally, or, in some cases, organisms that are intentionally introduced become pests. Global trade has resulted in increased numbers of invasive non-native pest species being introduced to new areas. There is a group of animal other than the insects, which cause the considerable yield losses to agricultural crops and commonly called as non insect pests. It includes mammals (monkey, wild animals etc), rodents, birds, molluscs, mites. The latest control problems are caused by non insect pests are not control by planting a resistant variety and advocate use of pesticides. Controlling these invasive species presents an unparalleled challenge worldwide.

Soybean (Glycine max L.Merill) has been found to affect and considerable losses caused by collar rot incited by Sclerotium rolfsii Sacc. Seed treatment with fungicides Carbendazim +Thiram in field and pot culture was found effective and significantly reduced pre-and post-emergence mortality in soybean Cv.MAUS-71 thereby increased the seed yield as well as test weight . In pot culture evaluation of bioagents and plant extracts , T.viride +T.harzianum combination and Neem extract was found effective in reducing pre-and post-emergence mortality. All the fungicides (7), bioagents (5) ,plant extracts (9) and non-target pesticides (8) evaluated in vitro (1000 and 2000 ppm) were found fungistatic/fungitoxic against S.rolfsii.However, Propioconazole recorded highest mycelial inhibition (85.28%), bioagent T.harzianum recorded(73.33%) maximum inhibition of mycelial growth, Neem extract was found effective (10 and 20 %) and recorded highest inhibition (73.37%).Nuvan was found most effective among the other pesticides and recorded maximum mycelial inhibition (72.03%) of the test pathogen.

Soybean belongs to the family Leguminoseae and sub-family Papilionoidae and believed originated from Eastern Asia. The crop is presently grown in most of the part of world and is a primary source of vegetable oil and protein. Among the bacterial diseases bacterial blight caused by Pseudomonas syringae is causing considerable losses in soybean.The highest diseases incidence was observed in Parbhani districts and the minimum disease incidence noticed in Jalna districts. The samples collected during survey were used for isolation of pathogen. The in vitro evaluation of chemical indicated that streptocycline (100 ppm) + copper oxychlrolide (0.25%) was significant inhibited the growth of pathogen. In natural condition the streptocycline (100 ppm) + copper oxychlrolide (0.25%) was found superior over rest of treatment. In evaluation of botanicals, Neem extract significantly in habited the growth (59.26 %), the same treatment was found superior in glasshouse condition.Among the antagonist bio-agents the Trichoderma viride was significantly superior in reduction of growth of pathogen.
