Downy mildew of sunflower is caused by the oomycete Plasmopara halstedii (Farl.) Berl. et de Toni. Italy has seen an increase in mildew infections in parallel with the spread of the crop. In the present situation, there is a substantial lack of information that could help farmers and researchers control the disease. The most reasonable explanation for pathogen spread appears to be the genetic variability of P. halstedii. To develop an effective control strategy, we conducted a preliminary test in the central part of the peninsula (Marche Region) to gather data on this variability.

We studied the role of the Arabidopsis At2g21490 (DH2) histidine-rich dehydrin gene in plant responses to copper and zinc stress. Transgenic plants overexpressing the DH2 gene were generated via Agrobacterium-mediated transformation. Progeny from both transgenic and non-transgenic (control) plants were cultivated hydroponically and subjected to short-term stress (100 µM CuCl2 or 200 µM ZnCl2 for 24 h) before analysis. The differences observed between transgenic and non-transgenic plants in the expression of phytochelatin synthase (NtPCS) and certain metal transporters (NtMTP1A, NtMTP1B,...

Anthracnose is one of the most destructive diseases that limits pepper production and quality worldwide. In this study, the causal agent of anthracnose in red chilli pepper in Southern Vietnam was collected and identified based on morphological characteristics and multilocus sequence regions (ITS, β-tubulin, GPDH, ACT). The antifungal activity of Bacillus amyloliquefaciens and Pseudomonas fluorescens was evaluated in vitro and in vivo under greenhouse conditions. The results revealed that the morphological analysis categorised the Colletotrichum isolates into three species: C....

A long-term experiment in the maise-pea cropping system was conducted in Palampur from October 2019 to September 2021 as part of the All India Coordinated Research Project on Weed Management (AICRP-WM). Ten methods for managing weeds, namely, T1 – hoeing, T2 – raised stale seedbed + hoeing, T3 – stale seedbed + hoeing, T5 – stale seedbed + mulch, T6 – raised stale seedbed + mulch, T4 – mulch 5 t per ha, T7 – intercropping fenugreek in rabi season and soybeans in kharif season,...

The wheat seed gall nematode Anguina tritici is a scientifically interesting nematode due to its aerial parasitic behaviour and ability to survive for years under desiccated conditions in seed galls. However, Anguina's life cycle and its correlation with host-plant growth and environment are poorly understood. Here, we conducted a microplot study at IARI, New Delhi, India, to examine the effects of early and late sowing dates on the life cycle of the wheat seed gall nematode using growing degree days (GDD). The study confirmed the presence of juvenile stages in the soft, undifferentiated floral mass and the upper one-third part of the...

The global decline in crop production poses a significant threat to food security, particularly in the context of a growing human population. Among various environmental constraints on agriculture, biotic stress, particularly that caused by insect pests, remains a major reason for yield losses. Traditionally, synthetic pesticides have been used to manage insect infestations; however, their excessive and non-targeted application has raised serious concerns regarding environmental pollution, adverse health effects, and the accelerated development of pesticide-resistant pest populations. In this context, plant-derived biocactive compounds, particularly...
