Organic matter in the pest and plant disease control: a meta-analysis

Abstract Background Pesticides have become a central public health problem and source of environmental contamination. The use organic matter is an important strategy to reduce synthetic agrochemicals, improve soil conditions, increase nutrient uptake by plants. Organic can also induce plant resistance against biotic stress in some circumstances. However, the results reported for different types applications are often very form each other, thus making difficult their interpretation hindering discouraging as valuable alternative. Identifying main factors involved efficacy these sustainable methodologies associated research gaps efficiency pesticides. Materials methods We performed comprehensive meta-analysis current recent scientific literature on control method pest disease, using data reduction techniques, such principal component analysis. found 695 articles listing keywords databases between 2010 2021 selected 42 that met inclusion criteria. Results In general, all showed high inhibition pests diseases. Control effectiveness was close 75% fungal diseases 67% control. most frequently vermicompost. humic substances greatest 74% when compared both bacterial disease concentration ranged from 1 500 mg L −1 , with highest concentrations used case application. Conclusions study demonstrated potential role elicitor plants, allowing partial/total pesticides crops. Despite works, mechanisms induction remains poorly studied. Graphical
