However, insect pests often necessitate pest management practices, which, while targeting pests, inadvertently disrupt pollinator foraging and visitation, resulting in reduced yields. Recognizing this, the impact of pest management modules on sunflower cultivation was studied, focusing on major insect pests, pollinators, and natural enemies. Over a two-year study, conducted at Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu (SKUAST-J), two major insect pests, <i>Helicoverpa armigera,</i> and <i>Spodoptera litura</i> (Noctuidae: Lepidoptera), alongside twenty-five pollinating bee species and five natural enemies were recorded within the sunflower ecosystem. Four pest management modules (M-I: deep plowing + hand picking + pheromone traps @ 4/acre + bird perches @ 10/acre + alternative spray of <i>Bacillus thuringiensis</i> @2 ml/lit and Spinosad 45 SC @0.2 ml/lit; M-II: deep plowing + hand picking + pheromone traps @ 4/acre + bird perches @ 10/acre + blanket spray of Neem oil @5 ml/lit and <i>Beauvaria bassiana</i> @ 2 ml/lit; M-III: deep plowing + hand picking + pheromone traps @ 4/acre + bird perches @ 10/acre + alternative spray of emamectin benzoate 5 SG @ 0.4 g/lit + chlorantraniliprole 18.5 SC @0.3 ml/lit; M-IV: control) were evaluated for their efficacy against major insect pests, bee visitation, and natural enemy populations. Module-III emerged as the most effective, reducing larval counts of <i>H. armigera</i> and <i>S. litura</i> by 81.05% and 82.98% over the control, respectively, comparable to Module-I. However, bee visitation varied among modules, with Module-III consistently exhibiting the lowest mean values and substantial reductions compared to the control (56.73%). Dynamics of natural enemies revealed significantly higher predator populations and parasitization rates in modules using non-synthetic chemical insecticides, namely Module-IV (control), Module-I, and Module-II, compared to Module-III. Seed yield analysis highlighted Module-I as the most influential, showcasing a 215.95% increase over the control, underscoring its agronomic and economic superiority (cost–benefit ratio: 1:1.89). These findings emphasize the importance of integrating non-synthetic chemical insecticides into pest management strategies to effectively combat major insect pests, yielding higher returns while maintaining harmony among pollinator and natural enemy populations.</p>","PeriodicalId":16838,"journal":{"name":"Journal of Plant Diseases and Protection","volume":"12 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2024-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142207830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The review also maps the distribution of the most dangerous genera, analyzes biological control methods for root knot nematodes <i>Meloidogyne</i> particularly, and identifies gaps and future research needs for sustainable PPN management. A total of 61 genera of PPNs were identified in Morocco, with <i>Meloidogyne</i> spp. being the most prevalent and dangerous genus, posing a serious threat to crop production in the country. The extensive distribution of PPNs, notably root knot, may be attributed to factors such as contaminated plant material and a lack of farmer awareness. Biological agents from Morocco’s ecosystems, including plant extracts, nematophagous fungi, and entomopathogenic nematodes, showed great potential as control agents for root knot nematodes.

In this sense, potyviruses have the greatest economic impact, since they can cause losses of more than 50% in agricultural yields. The movement of propagules between plantations without phytosanitary certification has facilitated the spread of viruses throughout the production areas. Understanding the relationships between the host, virus, vector, and ecosystem is fundamental for successful disease management and for increasing agricultural yields. The objective of the present work was to determine the effect of using virus-free planting material and plantain barriers on the production of two yam cultivars. For this purpose, potyvirus-free certified and non-certified planting material were evaluated inside and outside a live barrier based on plantain ‘Burro CEMSA’. The virus incidence and production of these plants were determined in each of the experiments conducted. It was possible to reduce the field incidence of viral diseases (average infection decreased from 60 to 15%).

This is of particular interest with regard to the occurrence of ash stem necrosis, a decisive factor for the severe course of the disease. In order to gain a more differentiated insight into the pathogen-load in ash stands, we analysed soil samples from four ash tree sites in southern Germany, covering a clone plantation, two seed orchards and a forest. The pathogen-load was determined using a quantitative TaqMan real-time PCR assay for ten to twenty plots per stand. Results obtained by the species-specific assay highlighted that the pathogen-load is heterogeneously distributed in the ash stands. <i>H. fraxineus</i> DNA targets were detected in 17% of the soil samples. The pathogen-load differed according to soil depth, with the highest pathogen abundance in the top 5 cm, followed by 5–10 cm and finally 10–15 cm. Pathogen-load and thereby infection pressure were found to be highly variable for the individual trees in one stand. Overall, the study discovered detectable levels of <i>H. fraxineus</i> in the soil of all four study sites, which supports the hypothesis that <i>H. fraxineus</i> can be found in the soil of ash stands. The qPCR approach was found to be an effective method for monitoring the load of <i>H. fraxineus</i> in soil and for demonstrating the successful application of the method on the sample type of custom-made spore traps.
