Abstract:
... This work explores the use of chitosan as an active matrix to develop biofungicides. Two chitosans from marine resources, of 4.8 and 78 kg/mol respectively, were structurally characterized. Both chitosans diluted in acidic conditions (lactic or acetic acid at 1%, v/v) were efficient in reducing the growth of Fusarium graminearum. Ammonium groups of chitosan chains were suggested as key determinant ...
... Trans-2-hexenal (T2H) has great commercial value for development as a biopesticide, but its toxicity risk to nontarget organisms is unknown. Here, the toxicity and underlying mechanism of T2H on zebrafish (Danio rerio) were investigated. The LC₅₀ (48 h) of T2H on zebrafish is 4.316 μg/mL, and the aldehyde group is essential to its toxicity. In 14-day chronic toxicity tests, 0.432 μg/mL T2H resulte ...

Abstract:
... Spinosad is one of the world's most widely applied natural bioinsecticides and its use has been growing rapidly in the past decade. Biologically based plant protection products can also have unexpected effects on beneficial arthropods. Previous studies examining the lethal and sublethal effects of spinosad on different groups of spiders have shown widely diverging results. This work aims at an ext ...

Abstract:
... The introduction of fall armyworm (FAW) Spodoptera frugiperda (JE Smith) (Lepidoptera: Noctuidae) on the African continent has led to paradigm shifts in pest control in maize systems, occasioned by year-round populations. The discovery of resident parasitoid species adapting to the new pest significantly informed decision-making toward avoiding highly hazardous synthetic insecticides to control th ...

Abstract:
... Several compounds produced by Actinomycetes group of bacteria have proven potential in inhibiting plant pathogenic fungi. In the present study, two microbial ethyl acetate extracts from Streptomyces were tested for their antifungal properties against Thielaviopsis paradoxa, the causal organism of stem bleeding disease in coconut. The cultural filtrates of 2 strains of Streptomyces (AFL-1 and AFL-2 ...
biopesticides, etc ; Tetranychus urticae; agriculture; climate; issues and policy; plant protection; spiders; Show all 7 Subjects
Abstract:
... Tetranychus urticae is one of the most important pests of many species of economically important crops, cultivated both under cover and in open ground. Feeding T. urticae reduces the size and quality of the yield. Nowadays, in connection with the popularization of organic farming and the green order policy, non-chemical methods that provide an effective reduction in the harmfulness of this spider ...

Abstract:
... Over the past decades, a growing interest in allelopathy has been recorded due to the effective use of allelochemicals as growth regulators, bioherbicides, insecticides, and antimicrobial crop protection in the sustainable agriculture field. So far, the genetic aspects of the allelopathic effects have been poorly studied, and the identification of allelopathic genes and/or genomic regions (QTLs) h ...

Abstract:
... A rapid LC/tandem MS method for the quantitative determination of matrine-based biopesticides is proposed for the analysis of fruit and vegetable samples. A simple extraction process by acidified methanol was selected, ensuring reduced solvent consumption and time, and allowing a simultaneous preparation of multiple sample extracts. Excellent chromatographic results were obtained in terms of peak ...
