The diamondback moth (DBM), Plutella xylostella (Linnaeus, 1758) (Lepidoptera: Plutellidae), is a severe and most destructive pest of cruciferous vegetables in many parts of the world, including Nepal. The natural history and ecology of the diamondback moth are summarized here, along with appropriate management options. Caterpillar is the most devastating stage of DBM that matures and causes “windowing” damage, leaving only the epidermis. Biological control, cultural practices, effective chemical control, botanical pesticides, and host plant resistance are the most viable options. Insecticide abuse and resistance concerns are likely to persist, as numerous research-based outcomes have proven that none of these measures will suffice independently. However, these techniques can complement each other and result in a better long-term management system when combined. This review highlights the integrated eco-friendly management strategies for DBM and other cruciferous insect pests. Integrated Pest Management (IPM), which focuses on sustainable production, has shown promising results. Modern management techniques include genetic modification, use of parasitoids, modified cultural methods, the precautionary application of chemicals, resistant cultivars, fungal, bacterial (Bt. based biopesticides), and viral entomopathogens, etc., which are found to be more effective and eco-friendlier.

Turkey is known as a top producer and exporter of apricots, both fresh and dried. More than half of Turkey's apricot production is provided by Malatya province. There are many pests and diseases affecting apricots in addition to climatic factors such as frost and hail. Partial shoot drying and sudden drying in apricot orchards have increased in recent years. In this study, it was aimed to determine the chemical control possibilities of Neoscytalidium dimidiatum (Penz.) Crous &Slippers, which is one of the fungal agents that cause partial branch drying and sudden drying in apricot orchards in Malatya province by in vitro studies. For this purpose, Kale 4-C isolate of N. dimidiatum collected from Malatya in a previous study was used. Mycelial growth of N. dimidiatum Kale 4-C isolate in PDA were observed in 0 (control), 0.01, 0.03, 0.1, 1, 3, 10, 30 ve 100 μg/mL concentrations of Azoxystrobin 250g/L, Trifloxystrobin %50, Tebuconazole %25, Floupyram 200 g/L+Tebuconazole 200 g/L, Cyprodinil+Fludioxonil %37.5+25, %70 Thiophanate-Methyl and 400 g/L Phosphorous acide fungicides applications. As a result of the study, Floupyram 200g/L+Tebuconazole 200g/L ve Cyprodinil+Fludioxonil %37.5+25 fungicides effectively inhibited the mycelial growth of the fungus.

This study was carried out to determine the plant protection practices of the garlic growers in Gaziantep province. For this purpose, a survey consisting of 20 questions and based on simple random sampling method was conducted with 81 growers in each of the districts of Araban, Oguzeli, Yavuzeli, Central, Nurdagı, Nizip and Karkamış districts in 2018. The data evaluated and expressed as percent ratio. According to the findings from the surveys, garlic growers stated that they preferred pesticide dealers suggestions for the selection and determination of doses of pesticides used in pests and diseases, they also stated that the price and expiration date were not an important factor in the selection of pesticides. In addition, it is found that growers avoid using the same pesticide continuously against same diseases and pests, they do not make any changes in there commended pesticide doses, pesticides leave residues on the products, they paid attention the time between the last application and harvest. It has been reported that the use of protective clothing and mask during the application by the growers is relative, they do not use pesticides as a mixture, they apply different processes to empty pesticide boxes. It was determined that garlic growers prefered chemical control and did not have knowledge about the concept of biopesticides.
