摘要:
The invention relates to a novel method to produce small RNAs targeting virulence factors, essential genes and /or antimicrobial resistance genes of phytopathogens. More specifically, the invention involves the expression of exogenous RNA interference (RNAi) precursor(s) in Chlorella cells, which in turn express and release Extracellular Vesicle (EV)-embedded antimicrobial small RNAs. These EVs can be collected from the cell-free medium of Chlorella cultures, and further concentrated and purified for biocontrol applications. Importantly, Chlorella EVs protect small RNAs from ribonuclease-mediated digestion, indicating that these lipid-based particles not only act as natural vectors of small RNAs towards pathogenic cells, but also presumably limit their degradation in the environment. The invention can thus likely be used to reduce the pathogenicity and growth of a wide range of pathogens or, potentially, to enhance beneficial effects and growth of plant-associated symbiotic and commensal microbes. Furthermore, because the integrity of Chlorella EV-embedded antimicrobial siRNAs remains unaltered when produced in photobioreactors, and when stored frozen, this method has the potential to be further exploited for the industrialization and manufacturing of a novel generation of microalgae-based biologicals.

摘要:
The present invention aims to supply formulas of agricultural agents with no undesirable effect on crops and low risk of running off of agricultural agents from a paddy field, due to the excellent dispersion of the active ingredients of agricultural agents as well as quick sank of the carriers into the water after dispersion, and being prepared at reasonably low costs. Formulation of agricultural agents characterized by containing active ingredients of agricultural agent, a porous carrier of which average particle diameter is in the range of 10 to 100 microns, a surfactant, a binder and a polymer of high water absorption.
摘要:
The invention relates to novel active ingredient combinations containing at least one known compound of formula (I), in which R is defined as cited in the description, and at least one additional known active ingredient from the classes of organophosphates or carbamates. Said combinations are extremely suitable for controlling animal pests such as insects, nematodes and undesired acarides.
