The increasing rate of fungicide use in agriculture is slower in recent years as compared to the data of 2000s (FAOSTAT, 2019). Many farmers are inclined towards the use of organic fungicides. Does the use of botanical fungicide play significant role for this situation?
Most fungicides are used to prevent the spread of viruses and bacteria, to protect the seeds, to disinfect the soil and for foliar application.
It is important to take into account that like other chemical products it is necessary to use it in moderation to avoid physiological damage to plants or harm to the environment, and for this reason there are alternatives that allow to reduce this problem with less risks to the environment, for example organic fungicides made from natural products, which are self-protective mechanisms. Useful for plants.
The use of postharvest biocontrol and biological products in general will probably continue to increase.
No, I think, that we must search new secondary metabolites from plants
Because, the massive use of the chemical fungicides induce the resistance of strains and the increase of the agrissiveness. So, many plants offered some interesting fungicidal molecules.
Yes mycoparasites such as Trichoderma viridiae and paecilomyces are commonly used as bio-fungicides.
Dear, Sagar Bhandari,,
The increase use of botanical fungicides and biofungicides in biocontrol programs are the main reason for slow increase in the use of chemical fungicide.
Best wishes
Some important bioagents fungi can be used effectively as biofungicides for controlling plant diseases, such as Trichoderma harzianum, T. koningii, T. viride, T. longibrachiatum, etc..
Also, some botanical extracts can be used significantly against plant pathogenic fungi which cause plant diseases.
With best wishes.
