Background: garlic reproduces mainly through clove planting, as sexual reproduction via seeds is uncommon. Growers encounter challenges with pathogens due to the larger size and vegetative nature of seed cloves, as well as the storage conditions conducive to fungal growth. Some Phyto-pathogenic fungi, previously unrecognized as garlic infections, can remain latent within bulb tissues long after harvest. Although outwardly healthy, these infected bulbs may develop rot under specific conditions. Aim of review: planting diseased seed cloves can contaminate field soil, with some fungal and bacterial infections persisting for extended periods. The substantial size of seed cloves makes complete eradication of deeply ingrained infections difficult, despite the use of systemic fungicides during the preplanting and postharvest phases. Additionally, viruses, resistant to fungicides, persist in vegetative material. They are prevalent in much of the garlic used for planting, and their host vectors are difficult to eliminate. To address these challenges, tissue-culture techniques are increasingly employed to produce disease-free planting stock. Key scientific concepts of the review: garlic faces a concealed spectrum of diseases that pose a global challenge, encompassing fungal threats like Fusarium’s vascular wilt and Alternaria’s moldy rot, bacterial blights, and the elusive garlic yellow stripe virus. The struggle to eliminate deeply ingrained infections is exacerbated by the substantial size of seed cloves. Moreover, viruses persist in garlic seeds, spreading through carrier vectors, and remain unaffected by fungicides. This review emphasizes eco-friendly strategies to address these challenges, focusing on preventive measures, biocontrol agents, and plant extracts. Tissue-culture techniques emerge as a promising solution for generating disease-free garlic planting material. The review advocates for ongoing research to ensure sustainable garlic cultivation, recognizing the imperative of safeguarding this culinary staple from an array of fungal and viral threats.

Background: Garlic primarily reproduces through vegetative propagation using seed cloves due to infrequent sexual reproduction by true seeds. Growers encounter challenges with pathogens due to the larger size and vegetative nature of seed cloves, as well as the storage conditions conducive to fungal growth. Some Phyto-pathogenic fungi, previously unrecognized as garlic infections, can remain latent within bulb tissues long after harvest. Although outwardly healthy, these infected bulbs may develop rot under specific conditions. Aim of Review: Planting diseased seed cloves can contaminate field soil, with some fungal and bacterial infections persisting for extended periods. The substantial size of seed cloves makes complete eradication of deeply ingrained infections difficult, despite the use of systemic fungicides during pre-planting and post-harvest phases. Additionally, viruses, resistant to fungicides, persist in vegetative material. They are prevalent in much of the garlic used for planting and their host vectors are difficult to eliminate. To address these challenges, tissue culture techniques are increasingly employed to produce disease-free planting stock. Key Scientific Concepts of Review: This review delves into crucial scientific aspects related to garlic propagation and health. Garlic primarily reproduces through vegetative propagation using seed cloves, facing challenges due to their large size and susceptibility to fungal infections. Some fungal pathogens, recently identified as garlic threats, remain dormant within bulbs long after harvest, potentially causing rot under specific conditions. Planting infected seed cloves can introduce pathogens into the soil, where they may persist. Deeply ingrained infections can be challenging to eradicate due to the size of seed cloves. Additionally, viruses persist in garlic seeds and spread through their carrier vectors, unaffected by fungicides. To address these issues, tissue culture techniques offer a promising approach to produce disease-free garlic planting material. This review explores these concepts, emphasizing the importance of producing disease-free garlic seeds and strategies for mitigation.

“…The increase in temperatures ends up reducing crop production, while causing the proliferation of weeds and pests, changes in rainfall regimes increase the probabilities of crop failure in the short term and reduction in productivity in the long term production [3]. The temperature of agricultural areas in Mexico has been increasing perceptibly since the 1990s [4], this increase in temperature brings with it modifications in agroclimatic variables such as the accumulation of cold in the winter period [5,6]. In northwest Mexico, climate change forecast of 2.5°C for the next ten years have already been exceeded [7]; In Sonora, average temperatures have increased by 3.59 °C during the summer and 3.3 °C in the winter [8], constituting a region under thermal stress.…”

Global warming has the potential to cause the reduction of the cold period available during the winter, which may affect the production of wheat and deciduous fruit trees. Wheat requires accumulated cold units (CU) to switch from a vegetative period to a productive one, making the phenological cycle slower and promoting greater productive yield. The objective was to analyze the accumulation of CU and wheat yield during the last five fall-winter agricultural seasons (2018-2019 to 2022-2023) in the Yaqui Valley, Sonora, Mexico. Data of air temperature were obtained from 21 meteorological stations from the network of automatic meteorological stations of the state of Sonora, located in the Yaqui Valley. The number of CU (≤ 10 °C) was calculated for the wheat season (November 15 to April 30) from the years 2018 to 2023, and the grain yield was obtained from the reports by the Agri-Food and Fisheries Information Service. Descriptive statistics of central tendency, dispersion and the Shapiro-Wilk test were performed to determine the normality of the data; also, correlation analysis and the simple linear regression model by least squares were performed. The 2022-23 crop season showed the highest average grain yield (7.79 t ha-1) and the highest average number of CU (882) among the five seasons analyzed. Wheat seasons 2018-2019 and 2019-2020 had an average number of CU lower than 500. The Pearson correlation analysis showed a highly positive correspondence between CU and grain yield. The linear regression model showed that starting from a base of 434 CU, wheat production per hectare would be 5.90 t, and it will increase 214.3 kg for every additional 100 CU.
