Entomopathogenic Nematode and Insect pest Management: A Review

Paper ID- AMA-21-09-2022-11687

The entomopathogenic nematodes of the genera Steinernema and Heterorhabditis have capacity to manage insect pests mutually and interact with bacteria of the genera Xenorhabdus and Photorhabdus. These nematodes kill insects within 24 to 28 hours by interacting with their symbiotic bacteria in contrary to other biological control agents that take days or weeks to do so. Entomopathogenic nematodes know to have great insect management potentially and also known safer to non targeted organism and effectively work with their symbiotic bacteria. The biological control agents like fungal bacteria and other micro-organisms require longer time for insect killing. The infective juveniles (IJs) are known to tolerate short-term exposure of various chemical compounds like insecticide, fungicides, herbicides, fertilizers including nematodes and growth regulators and provide opportunity of mass application. They are also known to be compatible with other biocontrol agents under various agro-climatic conditions. The use EPNs can also offer a cost-effective alternative to insect-pest control. Till today only about 12 species out of nearly 182 identified belonging to genera Steinernema and Heterorhabditis have been promoted to be used on commercial level. To help students and researcher understand their activity under field condition and to conduct in depth research on a variety of entomopathogenic nematode relative topics, this article summarises the work carried out in india & abroad integrated pest management systems. Although more research is needed, the use of EPNs can protect agriculture crops from the harm that insects do while having no adverse effects on people, animals, or the environment.

Response of Botanicals and Enzymes Activities as a Defense Mechanism against Root-knot nematode, Meloidogyne javanica in Tomato

Paper ID- AMA-19-09-2022-11685

Tomato (Solanum esculentum Mill) is an important vegetable crop and grown all around the world. It is one of the most important host for plant parasitic nematodes, mainly root-knot nematode (Meloidogyne javanica). Experiments was conducted to test the efficacy of botanicals (viz., garlic, parthenium, aak, datura, marigold and neem) against root-knot nematode in laboratory (0.5, 1, 2, 5 and 10 per cent concentration) as well as in pot and field condition (10 per cent concentration), PPO and PAL and Phenol were also estimated in tomato roots infected with root-knot nematode (M. javanica). The experimental results showed that all the botanicals significantly reduced the per cent hatched juveniles and increased the per cent mortality of juveniles, increased the level of PPO, PAL and phenol in tomato roots, increased the plant growth parameter and reduced the nematode reproduction as compared to untreated check. Among the tested botanicals neem leaves extract was found most effective treatment with minimum per cent hatched juveniles and maximum per cent mortality of juveniles @ 10 per cent concentration after 72 hrs followed by parthenium and garlic extract. Similarly, neem leaves extract @ 10 per cent concentration was found to be the best treatment to enhance PPO, PAL and phenol activity, plant growth parameter as well as in reducing nematode population in pot as well as field condition.

Allelopathic effect of leaf aqueous extract of Ipomoea carnea subsp. fistulosa on rice germination

Paper ID- AMA-19-09-2022-11684

Ipomoea carnea subsp. fistulosa (bush morning glory) is a alien invasive weed species, native of Latin America, spread throughout the fresh water ecosystems of tropic and sub – tropics [34]. I. carnea subsp. fistulosa infestation generally found in undisturbed areas, through release of allelochemical monopolise the natural resource, thus replace the original native species [14], [35]. Water from fresh water tanks and pond obviously feed to rice crop. Allelopathic effect of I. carnea subsp. fistulosa is not reported on any crop plants. This is the novel work which examine the allelopathic effect of I. carnea subsp. fistulosa aqueous leaf extract on rice. The leaf samples for aqueous extract collected from near by infestation. Here, aqueous leaf extract treatments namely 5, 10, 15, 20 per cent and control (distilled water) employed. Two sets of germination experiments were conducted viz., petri dish method and roll towel method with 25 seeds each. Periodic observations clearly indicates the potential inhibition of leaf aqueous extract of I. carnea subsp. fistulosa on rice crop germination.

The present study sought to determine the effectiveness of growth, yield and quality of strawberries in different container sizes and growing media. The experiment was carried out at Research Farm, Division of Fruit Science, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, Main campus, Chatha, during the year 2020-21. Three replicates of each plant were tested using containers of six different sizes, i.e., (24 cm × 24 cm × 14 cm), (25 cm × 21 cm × 12 cm), (20 cm × 20 cm ×10 cm), (37 cm × 23 cm × 9 cm), (35 cm × 18 cm × 14 cm) and (23 cm × 23 cm × 10 cm) in factorial randomized block design. The strawberry plants were planted in containers filled with a growing media of cocopeat, perlite and vermicompost in the following ratios: 1:1:1, 2:1:1, 3:1:1, 4:0:1, 4:1:0, 4:1:1, respectively, and control. At the end of the study, observations on the growth, shoot, leaf, flower, root and biochemical parameters of each plant were recorded. Among all the treatments, the results showed plants raised in PVC pots with a growing media ratio of 3:1:1 (C2T3) had significantly greater height, higher growth, maximum flowering and fruiting. Also, the cost and returns were reported to be higher in polyethylene bags with a growing media ratio of 3:1:1 (C1T3) with a benefit cost ratio of 1:1.70. Thus, it is recommended that for strawberry production in open areas, PVC pots with growing media in a 3:1:1 ratio be used, as this will ensure greater success in plant establishment and provide disease-free, healthy strawberries. It is also indicated that soilless production of containerized strawberries cv. Chandler can be taken as commercial cultivation.

The current investigation aims to study the effects of different IBA concentrations and growing media on karonda cuttings at Research Farm, Faculty of Agriculture, Division of Fruit Science at Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, Main Campus, Chatha during the year 2018-19. The treatments consisted combination of three levels of IBA (7000, 8000 and 9000 ppm) with three different concentrations of sucrose (3, 4 and 5% respectively) and also contains the three different types of rooting media viz., soil, sand, FYM (1:1:1), vermiculite (100%) and cocopeat (100 %) which was laid out in a factorial completely randomized design with three replications. The results obtained from the study exhibited that the shortest time to first sprouting i.e. 9.5 DAP, maximum sprouted cuttings i.e. 16.00, the maximum percentage of cuttings that sprouted i.e. 80 percent the longest shoot (8.46 cm), maximum number of shoots per cutting (6.15), longest diameter of shoot (8.31 mm), maximum shoot fresh weight (2.21 g), maximum shoot dry weight (1.16 g), highest leaf number per cutting (16.80), total leaf area (4.26 cm2), maximum leaf fresh weight (0.27 g), maximum leaf dry weight (0.14 g) and maximum leaf chlorophyll content (SPAD value of 75.20) were recorded with combination of 8000 ppm IBA, 4 percent sucrose and vermiculite media. Furthermore, the total number of roots per cutting (13.12), longest root length (8.46 cm), mean root length (11.30 mm), root fresh weight (0.53 g), root dry weight (0.29 g) and survival percentage (43.33) were also found to be highest with 8000 ppm IBA, 4 percent sucrose and vermiculite media. From this study, it is concluded that the combined effect of 8000 ppm IBA, 4 percent sucrose and vermiculite had a great impact on the successful propagation of karonda by cuttings, as it yielded best results in terms of growth and rooting parameters.
