Pests and diseases threaten cacao production worldwide. Agroforestry systems are traditionally seen by farmers as one of the causes increased pest disease incidence, in contrast with full-sun monocultures. Cultural management practices—e.g. regular tree pruning, frequent pod harvest, removal infested pods, weed management—have been reported to be crucial for management. We performed two experiments purpose assessing effect (i) different systems, (ii) frequency harvest pods on incidence pests...

Mixed cropping has been suggested as a resource-efficient approach to meet high produce demands while maintaining biodiversity and minimizing environmental impact. Current breeding programs do not select for enhanced general mixing ability (GMA) neglect biological interactions within species mixtures. Clear concepts efficient experimental designs, adapted mixed encoded into appropriate statistical models, are lacking. Thus, model framework GMA SMA (specific ability) was established. Results...

Legume/cereal intercropping has the potential to maximize use of resources raise yields due enhanced nitrogen (N) fixation by legume root nodules, while high N fertilization may inhibit nodulation legume. However, whether legume/cereal can promote accumulation soil storage with and its underlying mechanism are less clear. Here, we evaluated long-term (5 years) effects maize/peanut mineral on peanut total content cycling functional genes. The experiment includes two planting patterns (peanut...

Plant health is recognised as a key element to ensure global food security. While plant breeding has substantially improved crop resistance against individual pathogens, it showed limited success for diseases caused by the interaction of multiple pathogens such root rot in pea (Pisum sativum L.).

Soil-borne pathogens cause severe root rot of pea (Pisum sativum L.) and are a major constraint to cultivation worldwide. Resistance against individual pathogen species is often ineffective in the field where multiple form complex (PRRC) conjointly infect plants. On other hand, various beneficial plant-microbe interactions known that offer opportunities strengthen plant health. To account for whole rhizosphere microbiome assessment resistance pea, an infested soil-based screening assay was...

ABSTRACT Fungal plant pathogens cause major crop losses worldwide, with many featuring compartmentalised genomes that include both core and accessory regions, which are believed to drive adaptation. The highly host‐specific fungus Colletotrichum lupini greatly impacts lupin ( Lupinus spp.) cultivation. This pathogen is part of clade 1 the C. acutatum species complex comprises four genetically uniform, presumably clonal, lineages (I–IV). Despite this, variation in virulence morphology has...
