Efficacy of Jatropha, Annona and Parthenium biowash on Sclerotium rolfsii, Fusarium oxysporum f. sp. ciceri and Macrophomina phaseolina, pathogens of chickpea and sorghum

The demand for products and technologies based on plants to control plant pathogens has increased in recent years due to concern about the use of hazardous pesticides. In the present investigation, washings of vermicompost (called biowash) prepared from foliage of Jatropha (Jatropha curcas), Annona (Annona squamosa) and Parthenium (Parthenium hysterophorus) were evaluated against fungal pathogens viz. Fusarium oxysporum f. sp. ciceri (FOC; causes wilt in chickpea), Sclerotium rolfsii (causes collar rot in chickpea) and Macrophomina phaseolina (causes charcoal rot in sorghum). Crude biowash of the botanicals were partitioned against ethyl acetate and the resultant organic and aqueous fractions were tested against the fungi. Similarly, crude biowash was also passed through C18 solid phase extraction cartridges and the resultant adsorbed and non-adsorbed fractions were tested against the fungi. Organic fractions of all the three biowash at 0.5% inhibited the growth of S. rolfsii between 78 and 87%, M. phaseolina between 62 and 65%, whereas only Parthenium was able to effectively inhibit FOC (91%), compared to control. Adsorbed fractions of all the three biowash at 0.5% inhibited the growth of S. rolfsii between 81 and 92%, M. phaseolina between 76 and 77% and FOC between 26 and 49%, compared to control. Both aqueous and non-adsorbed fractions of all the three biowash did not inhibit any of the fungi. Since Jatropha biowash showed consistently higher levels of inhibition (>80%) in both fractionation methods on S. rolfsii, this was selected for further purification of their secondary metabolites. When the organic fraction of Jatropha biowash was further fractionated by C18 open column chromatography with eluent 5, 10, 20, 40, 60, 80 and 100% MeOH fractions, only 80% methanol (MeOH) fraction was found to inhibit S. rolfsii. The active 80% MeOH fraction showed three clear bands when chromatographed on Silica Gel 60 F254 thin layer chromatography (TLC) plates with Rf values 0.95, 0.90 and 0.70. Hence, it was concluded that one of these three bands could be the active ingredients that inhibited S. rolfsii and can be further exploited as a bio-fungicide

Biocontrol of charcoal-rot of sorghum by actinomycetes isolated from herbal vermicompost

A total of 137 actinomycetes, isolated from 25 different herbal vermicomposts, were characterized for their antagonistic potential against Macrophomina phaseolina by dual-culture assay. Of them, eight most promising isolates (CAI-17, CAI-21, CAI-26, CAI-68, CAI-78, KAI-26, KAI-27 and MMA-32) were characterized for the production of siderophore, chitinase, protease, hydrocyanic acid (HCN), indole acetic acid (IAA) and further evaluated for their antagonistic potential against M. phaseolina by blotter-paper assay and in greenhouse. All the eight isolates produced HCN and IAA, seven produced siderophore (except CAI-78) and protease (except KAI-27) and four produced chitinase (CAI-26, KAI-26, KAI-27 and MMA-32). In the blotter-paper assay, no charcoal-rot infection was observed in KAI-26 and KAI-27-treated sorghum roots, indicating complete inhibition of the pathogen, while the other isolates showed 47 to 88% lesser charcoal-rot infection compared to the control. In the antifungal activity test against M. phaseolina (in greenhouse on sorghum), all the isolates increased in shoot dry mass by 28 to 53% and root dry mass by 5 to 21%, over the control. In order to confirm the plant growth promoting (PGP) traits of the isolates, the green house experiment was repeated, but in the absence of M. phaseolina. The results further confirmed the PGP traits of the isolates as evidenced by 15 to 34% increase in shoot dry mass on six isolates (except CAI-26 and KAI-27), 14 to 57% increase in root dry mass on five isolates (except CAI-68, KAI-26 and KAI-27), 17 to 60% increase in root length on five isolates (except CAI-17, CAI-21 and CAI-68) and 10 to 64% increase in root volume on six isolates (except CAI-17 and CAI-68). Culture filtrate of three potential actinomycetes (CAI-21, CAI-26 and MMA-32) at 0.5% inhibited the growth of M. phaseolina, indicating that the metabolites of these actinomycetes were responsible for the inhibition. The sequences of 16S rDNA gene of the isolates matched with Streptomyces but with different species in BLAST analysis. This study indicates that the selected actinomycetes have the potential for PGP and control of charcoal-rot disease in sorghum

Biological control of Botrytis cinerea and plant growth promotion potential by Penicillium citrinum in chickpea (Cicer arietinum L.)

A total of 48 fungi were characterised for their antagonistic potential against Botrytis cinerea causing Botrytis Gray Mold (BGM) disease in chickpea by dual culture and metabolite production assays. The culture filtrate of the most promising isolate, VFI-51, was purified by various chromatographic techniques and identified as ‘citrinin’ by nuclear magnetic resonance and mass spectrometry studies. The efficacy of citrinin was demonstrated to control BGM in chickpea under greenhouse conditions. The sequences of 18S rDNA gene of the VFI-51 matched with Penicillium citrinum in BLAST analysis. The VFI-51 produced siderophore, hydrocyanic acid, indole-3-acetic acid, lipase, protease and β-1,3- glucanase; grew well in NaCl (up to 15%), at pH between 7 and 11 and temperatures between 20°C and 40°C; and was compatible with fungicides bavistin and thiram. Under greenhouse and field conditions, VFI-51 significantly enhanced the nodule number, nodule weight, root and shoot weight and stover and grain yield over the un-inoculated control. In the rhizosphere, VFI-51 also significantly enhanced total N, available P and OC over the un-inoculated control. Scanning electron microscopy analysis revealed that VFI-51 colonised on the roots of chickpea. This study concluded that VFI-51 has the potential for biocontrol of BGM and plant growth promotion in chickpea

Efficacy of botanical extracts and entomopathogens on control of Helicoverpa armigera and Spodoptera litura

Interest in biological control of insect-pests of economically important plants has been stimulated in recent years by trends in agriculture towards greater sustainability and public concern about the use of hazardous pesticides. Botanicals and microorganisms have the capability to synthesize biologically active secondary metabolites such as antibiotics, herbicides and pesticides. In this investigation, washings of herbal vermicompost (called biowash; viz. Annona, Chrysanthemum, Datura, Jatropha, Neem, Parthenium, Pongamia, Tridax and Vitax) and plant growth promoting (PGP) bacteria [viz. Bacillus subtilis (BCB-19), Bacillus megaterium (SB-9), Serratia mercescens (HIB-28) and Pseudomonas spp. (SB-21)] and fungus (Metarhizium anisopliae) were evaluated for their efficacy against Helicoverpa armigera and Spodoptera litura. When the feed was treated with crude biowash for healthy larvae (4-day old), 42 and 86% mortality and 32 and 71% weight reduction over control was reported for H. armigera, while in the case of S. litura, it was between 46 and 74% larval mortality and 47 and 77% weight reduction over control. When healthy larvae were treated with PGP bacteria and fungus, the mortality rate varied between 59 and 73%, with 55 and 92% weight reduction over control on H. armigera, while for S. litura, 54 and 72% larval mortality and 44 and 79% weight reduction over control was reported. The results of the compatibility studies (entomopathogenic potential biowash of the botanicals with PGP bacteria and fungus) indicate that there was no definite sign of suppression of any of the botanicals on the PGP bacteria and fungus, except Datura with B. subtilis BCB-19, whereas, there was definite sign of enhanced growth of B. megaterium SB-9 with all the botanicals. Compatibility studies between PGP bacteria and fungus showed that all bacteria are compatible with each other except M. anisopliae. Crude biowash of the promising botanicals (Annona, Datura, Jatropha, Neem, Parthenium and Pongamia) were further fractionated on C18 solid phase extraction cartridge (SPE) and the resultant adsorbed and non-adsorbed fractions were tested against H. armigera. Results indicate that both adsorbed as well as non-adsorbed fractions showed significant mortality on H. armigera. Adsorbed fractions of all the six biowash showed mortality between 81 and 93% (64 and 73% for non-adsorbed fraction) over control and the weight reduction of the larvae was found between 73 and 91% (80 and 97% for non-adsorbed fraction) over control. It was therefore concluded that the aforementioned six botanicals and five entomopathogens has great potential in the management of H. armigera and S. litur

Biological options for crop health (Nutrition, pest and disease) management-sanguine to sustainable agriculture

Interest in biological control of plant insect pests and pathogens has been stimulated in recent years by trends in agriculture towards greater sustainability and public concern about the use of hazardous pesticides. Microorganisms have the capability to synthesize many different biologically active secondary metabolites such as antibiotics, herbicides, pesticides, antiparasitic and enzymes like cellulase, chitinase and xylanase. Microbial collection at ICRISAT, Patancheru, India has over 2000 accessions of bacteria and actinomycetes isolated from various sources and/or niches of composts, rhizosphere and rhizoplane soil samples of sorghum and rice. These accessions possess at least one of six agriculturally beneficial traits studied viz. phosphate solublization, siderophore production, cellulose degradation, nitrogen fixation, antagonism to disease causing fungi and fluorescent Pseudomonas. In addition to that ICRISAT has also identified 28 entomopathogenic bacteria and actinomycetes capable of managing the mos

Plant growth-promoting traits of biocontrol potential bacteria isolated from rice rhizosphere

Seven isolates of bacteria (SRI-156, SRI-158, SRI-178, SRI-211, SRI-229, SRI-305 and SRI-360) were earlier reported by us as having potential for biocontrol of charcoal rot of sorghum and plant growth promotion (PGP) of the plant. In the present study, the seven isolates were characterized for their physiological traits (tolerance to salinity, pH, temperature and resistance to antibiotics and fungicides) and further evaluated in the field for their PGP of rice. All the seven isolates were able to grow at pH values between 5 and 13, in NaCl concentrations of up to 8% (except SRI-156 and SRI-360), temperatures between 20 and 40?C and were resistant to ampicillin (>100 ppm; except SRI-158 and SRI-178) but sensitive (<10 ppm) to chloramphenicol, kanamycin, nalidixic acid, streptomycin (except SRI-156 and SRI-211) and tetracycline. They were tolerant to fungicides benlate and captan, except SRI-158 and SRI-178, bavistin and sensitive to thiram (except SRI-156 and SRI-211) at field application level. In the field, four of the seven isolates (SRI-158, SRI-211, SRI-229 and SRI-360) significantly enhanced the tiller numbers, stover and grain yields, total dry matter, root length, volume and dry weight over the un-inoculated control. In the rhizosphere soil at harvest, all the isolates significantly enhanced microbial biomass carbon (except SRI-156), microbial biomass nitrogen and dehydrogenase activity (up to 33%, 36% and 39%, respectively) and total N, available P and% organic carbon (up to 10%, 38% and 10%, respectively) compared to the control. This investigation further confirms that the SRI isolates have PGP properties

Management of Soil-Borne Diseases of Grain Legumes Through Broad-Spectrum Actinomycetes Having Plant Growth-Promoting and Biocontrol Traits

Chickpea (Cicer arietinum L.) and pigeonpea (Cajanus cajan L.) are the two important grain legumes grown extensively in the semiarid tropics (SAT) of the world, where soils are poor in nutrients and receive inadequate/erratic rainfall. SAT regions are commonly found in Africa, Australia, and South Asia. Chickpea and pigeonpea suffer from about 38 pathogens that cause soil-borne diseases including wilt, collar rot, dry root rot, damping off, stem canker, and Ascochyta/Phytophthora blight, and of which three of them, wilt, collar rot, and dry root rot, are important in SAT regions. Management of these soil-borne diseases are hard, as no one control measure is completely effective. Advanced/delayed sowing date, solarization of soil, and use of fungicides are some of the control measures usually employed for these diseases but with little success. The use of disease-resistant cultivar is the best efficient and economical control measure, but it is not available for most of the soil-borne diseases. Biocontrol of soil-borne plant pathogens has been managed using antagonistic actinobacteria, bacteria, and fungi. Actinobacterial strains of Streptomyces, Amycolatopsis, Micromonospora, Frankia, and Nocardia were reported to exert effective control on soil-borne pathogens and help the host plants to mobilize and acquire macro- and micronutrients. Such novel actinomycetes with wide range of plant growth-promoting (PGP) and antagonistic traits need to be exploited for sustainable agriculture. This chapter gives a comprehensive analysis of important soil-borne diseases of chickpea and pigeonpea and how broad-spectrum actinomycetes, particularly Streptomyces spp., could be exploited for managing them
