    STUDIES ON BIOCONTROL POTENTIAL OF METHYLOTROPHIC BACTERIA AGAINST Exserohilum turcicum PATHOGEN OF MAIZE (Zea mays)
    (Acharya N G Ranga Agricultural University, Lam, Guntur, 2024-09-27) M. ADITHYA; Dr. V. MANOJ KUMAR
    Maize (Zea mays L.) is the third most important cereal crop grown in India after rice and wheat. Yield potential of maize is mainly affected by various biotic and abiotic stresses. It is attacked by a wide range of foliar and stem diseases at different growth stages. Among the various foliar diseases affecting maize, Turcicum leaf blight caused by Exserohilum turcicum (Pass.) Leonard and Suggs. is the most destructive and prevalent disease causing significant yield loss. Keeping in view of importance of this disease, studies were conducted on the prevalence of the disease in major maize growing mandals of Guntur district of Andhra Pradesh during rabi, 2020-2021. Survey in Guntur district revealed 31.53% of Turcicum leaf blight incidence incited by the fungus E. turcicum. Among the surveyed mandals, the highest disease incidence of 33.65% was recorded in Chebrolu mandal and least disease incidence of 29.55% was recorded in Duggirala mandal. As many as 35 methylotrophic bacterial isolates were isolated from the rhizospheric and phyllospheric ecosystem of maize and their morphological and cellular characterization was done. Morphologically most of them were light pink coloured, round shaped, smooth textured opaque colonies with entire margin and convex elevation. Microscopic studies revealed that most of them were single rod shaped Gram negative cells. Dual culture technique was carried out to evaluate the antagonistic potential of methylotrophic isolates against E. turcicum. The test pathogen was significantly inhibited by all 35 methylotrophic bacterial isolates tested. Five isolates viz., PPM 2, PPM 4, PPM 6, PPM 8 and PPM 13 were found to be the the most promising antagonists among all isolates with mycelial inhibition of 63.12, 61.67, 60.95, 59.68 and 59.42 per cent respectively. Microscopic examinations of the interaction zone revealed distinctive morphological changes in the fungal mycelium, including hyphal thinning, shortening xiv of hyphal septa, swelling, wrinkling, protoplasm disintegration, clustering of hyphae and hyphal tip shearing. Sealed plate experiment was carried out to evaluate the ability of methylotrophic isolates to produce volatile organic compounds. Among all the tested isolates, PPM 2 was found to be superior in volatile production with the appearance of restricted growth of fungal mycelium at their periphery during all hours of incubation followed by PPM 4, PPM 6, PPM 8 and PPM 13. Change in colour of the fungal mycelium from black to white due to the action of volatiles was also noticed. Physiological characterization of the five potential methylotrophic isolates revealed that neutral to alkaline pH ranging from 7 to 9 support maximum growth of methylotrophic bacteria and optimum growth occurs at pH 7. In case of salt tolerance, methylotrophic isolates exhibited maximum growth at 2.5 % NaCl concentration. The growth was decreased with increasing concentration. All methylotrophic isolates showed variable response to antibiotics. All the five potential methylotrophic isolates were tested positive for biochemical characters such as utilization of nitrogen sources, production of protease, amylase, catalase and siderophores whereas, only PPM 2, PPM 4 and PPM 8 poduced auxin. PPM 2 and PPM 8 were found positive for HCN production while PPM2 and PPM 4 exhibited phosphate and potash solubilizing actvity. All of them showed a negative reaction for ONPG, H2S production, methyl red and phenyl alanine deamination. The plant growth promotional ability of methylotrophic bacteria was evaluated under pot culture without pathogen inoculation. All the potential methylotrophic isolates significantly improved shoot length, root length and germination percentage of maize seedling over un-inoculated pathogen control and Mancozeb check. The treatment 7 where co-inoculation of all five potential methylotrophic isolates was done, was found to be superior over all other treatments in enhancing germination, shoot length, root length and vigour index of plants. Effect of methylotrophic isolates in plant growth promotion of maize under pathogen stressed condition was assessed after seed treatment followed by two foliar sprays with antagonists. Co-inoculation of all five methylotrophic isolates was found to be significantly superior over all other treatments in enhancing shoot length, root length, leaf length and leaf width at 60 days after sowing. Among different treatments employed for management of Turcicum leaf blight under green house conditions, treatment 8 where co-inoculation of all five potential methylotrophic isolates was done, was found to be superior in disease control with 46.68% inhibition over control which was found to be on par with the disease reduction by the chemical check.

    INTEGRATED WEED MANAGEMENT IN KABULI CHICKPEA
    (Acharya N G Ranga Agricultural University, Lam, Guntur, 2024-08-22) VINUKONDA VENKATA SAI TEJASWINI; Dr. K. SRINIVASULU
    A field experiment entitled “Integrated weed management in kabuli chickpea” was conducted during rabi 2022-2023 on clay soils at the Agricultural college farm, Bapatla of Acharya N.G. Ranga Agricultural University, Guntur. The experiment was laid out in randomized block design with eleven treatments and three replications. The treatments consisted of T1 : Weedy check, T2: Hand weeding at 15 DAS and 30 DAS, T3: Butachlor @ 1.5 kg a.i. ha-1 as PE, T4: Butachlor @ 1.5 kg a.i. ha-1 as PE fb Sodium Acifluorfen @ 160 g + Clodinafop Propargyl @ 80 g a.i. ha-1 as PoE at 30 DAS, T5: Butachlor @ 1.5 kg a.i. ha-1 as PE fb Fomesafen @ 110 g + Fluazifop-p-butyl @ 110 g a.i. ha-1 as PoE at 30 DAS, T6: Butachlor @ 1.5 kg a.i. ha-1 as PE fb Topramezone @ 25 g a.i. ha-1 as PoE at 30 DAS, T7: Butachlor @ 1.5 kg a.i. ha-1 as PE fb Quizalofop ethyl @ 50 g a.i. ha-1 as PoE at 30 DAS, T8: Butachlor @ 1.5 kg a.i. ha-1 as PE fb Hand weeding at 30 DAS, T9: Butachlor @ 1.5 kg a.i. ha-1 as PE fb Intercultivation at 30 DAS, T10 : Intercultivation at 15 DAS and 30 DAS, T11 : Hand weeding at 15 DAS fb Intercultivation at 30 DAS. The chickpea variety used in the experiment was NBeG-119. Chickpea crop was sown on well prepared experimental plot. The crop was supplied with recommended dose of 20 kg N, 50 kg P2O5 and 40 kg K2O fertilizers as basal. Application of both pre emergence and post emergence herbicides were done as per the treatments. Pre emergence herbicide was sprayed to the respective treatments on the next day of sowing. Post emergence herbicides were sprayed on 30th day after sowing on actively growing weeds as a blanket spray. Hand weeding and Intercultivation were done to the respective treatments. Plant protection measures were taken as per the recommendations of ANGRAU. The data on plant height (cm), number of branches plant-1, dry matter production (g m-2), crop growth rate, relative growth rate, number of pods plant-1, number of seeds pod-1, test weight (g), seed and haulm yield (kg ha-1) and xv harvest index (%) were recorded as per standard procedures. Data were analyzed using ANOVA and the significance was tested by Fisher's least significance difference. The predominant weed species observed in the experimental plot were grasses like Cynodon dactylon, Dinebra retroflexa, Dactylactenium aegyptium and Chloris barbata, sedge (Cyperus rotundus) and broad leaved weeds like Trichodesma indicum, Cleome viscosa, Digera arvensis, Phyllanthus niruri, Parthenium hysterophorus, Euphorbia hirta, Chrozophera rottleri and Physalis minima. Lower density and dry weight of weeds were observed with all the weed management practices over the weedy check. The density and dry weight of weeds recorded with hand weeding at 15 DAS and 30DAS was on par with butachlor @ 1.5 kg a.i. ha-1 as PE fb hand weeding at 30 DAS. Among the herbicide combinations, butachlor @ 1.5 kg a.i. ha-1 as PE fb topramezone @ 25 g a.i. ha-1 as PoE at 30 DAS performed better throughout the crop growth period than other treatments. All the herbicide combinations, except for quizalofop ethyl, showed phytotoxic effect on the chickpea crop. Butachlor @ 1.5 kg a.i. ha-1 as PE fb sodium acifluorfen @ 160 g + clodinafop propargyl @ 80 g a.i. ha-1 as PoE at 30 DAS caused slight phytotoxicity and the crop recovered within 7-14 days after spraying. In butachlor @ 1.5 kg a.i. ha-1 as PE fb fomesafen @ 110 g + fluazifop-p-butyl @ 110 g a.i. ha-1 as PoE at 30 DAS treatments the crop recovered within 14-21 days after spraying. All the growth, yield attributes and yield were found superior in hand weeding at 15 DAS and 30 DAS and butachlor @ 1.5 kg a.i. ha-1 as PE fb hand weeding at 30 DAS over rest of the treatments, whereas, 77.5 % yield reduction was noticed in weedy check treatment. Among the herbicide combinations studied, butachlor @ 1.5 kg a.i. ha-1 as PE fb sodium acifluorfen @ 160 g + clodinafop propargyl @ 80 g a.i. ha-1 as PoE at 30 DAS was found superior and on par with butachlor @ 1.5 kg a.i. ha-1 as PE fb fomesafen @ 110 g + fluazifop-p-butyl @ 110 g a.i. ha-1 as PoE at 30 DAS. Hand weeding at 15 and 30 DAS recorded higher gross returns (Rs.1,56,668 ha-1) but higher net returns were obtained with butachlor @ 1.5 kg a.i. ha-1 as PE fb hand weeding at 30 DAS (Rs. 1,04,783 ha-1) as hand weeding twice was expensive. Higher benefit cost ratio observed with butachlor @ 1.5 kg a.i. ha-1 as PE fb intercultivation at 30 DAS (2.23). Thus, the present investigation clearly revealed that butachlor @ 1.5 kg a.i. ha-1 as PE fb hand weeding at 30 DAS is the best integrated weed management practice for better weed control and monetary terms. Among the herbicide combinations, butachlor @ 1.5 kg a.i. ha-1 as PE fb sodium acifluorfen @ 160 g + clodinafop propargyl @ 80 g a.i. ha-1 as PoE at 30 DAS was found to be superior.
