Preventive and Curative Effects of Treatments to Manage Strawberry Root and Crown Rot Caused by .

Strawberry root and crown rot caused by the fungus is an emerging disease that has caused yield losses of up to 70% in Mexico and other regions worldwide. This research evaluated the effects of biological and chemical fungicides applied as preventive and curative applications for controlling root and crown rot caused by in strawberries under greenhouse conditions. Treatments included these chemical fungicides: prochloraz, prochloraz + thiram, cyprodinil + fludioxonil, difenoconazole + azoxystrobin, iprodione, captan, thiram, pydiflumetofen + fludioxonil, fluxapyroxad + pyraclostrobin, and hymexazol; each was applied at commercial doses.

Tomato Plant Microbiota under Conventional and Organic Fertilization Regimes in a Soilless Culture System.

Tomato is the main vegetable cultivated under soilless culture systems (SCSs); production of organic tomato under SCSs has increased due to consumer demands for healthier and environmentally friendly vegetables. However, organic tomato production under SCSs has been associated with low crop performance and fruit quality defects. These agricultural deficiencies could be linked to alterations in tomato plant microbiota; nonetheless, this issue has not been sufficiently addressed.

Identification based on morphological and molecular characters of Phassus huebneri (Geyer) (Lepidoptera: Hepialidae), a ghost moth feeding on blackberry in Michoacán, Mexico: its biology and parasitoids.

Larvae of an unidentified Lepidopteran hepialid were found boring stems and crown roots of blackberry (Rubus sp.) in Michoacán, Mexico. In this study, the morphological and molecular identification of larvae and adults of this insect was performed.

A Comprehensive Evaluation of Primer Sets for Analysis of Host-Associated Microbiota.

is one of the most important bacterial groups within the Proteobacteria phylum. This bacterial group includes pathogens, commensal and beneficial populations. Numerous gene PCR-based assays have been designed to analyze diversity and relative abundance, and, to the best of our knowledge, 16 primer pairs have been validated, published and used since 2003.

Comparative Performance of Fungicides and Biocontrol Products in the Management of Fusarium Wilt of Blackberry.

Fusarium wilt of blackberry (FWB) is an emerging disease caused by a species complex. More than 3,000 ha of blackberry ( spp.) crops have been lost in Mexico since 2011.

In a belowground multitrophic interaction, Trichoderma harzianum induces maize root herbivore tolerance against Phyllophaga vetula.

Background: Trichoderma spp. are soil fungi that interact with plant roots and associated biota such as other microorganisms and soil fauna. However, information about their interactions with root-feeding insects is limited.

An Emerging Strawberry Fungal Disease Associated with Root Rot, Crown Rot and Leaf Spot Caused by in Mexico.

In the 2017 strawberry season, several transplant losses reaching 50% were observed in Zamora, Michoacán Valley, Mexico, due to a new fungal disease associated with root rot, crown rot, and leaf spot. In this year the disease appeared consistently and increased in the following seasons, becoming a concern among strawberry growers. Thus, the aim of this research was to determine the etiology of the disease and to determine the in vitro effect of fungicides on mycelial growth of the pathogen.

Insecticide resistance of adults and nymphs of Asian citrus psyllid populations from Apatzingán Valley, Mexico.

Background: Control of the Asian citrus psyllid Diaphorina citri Kuwayama, the most important pest of citrus worldwide, is based on the use of insecticides, though unsatisfactory results have recently been reported. In this study, insecticide resistance of D. citri to three insecticides (bifenthrin, malathion, and chlorpyrifos) was examined.
