Why is organic pesticides better?
Natural pesticides have many advantages over synthetic ones and may be more cost-effective as a whole, considering the environmental cost of chemical alternatives. Natural pesticides are biodegradable, barely leave residues in the soil and are less likely to harm humans or animals.
Are organic pesticides better for the environment?
Organic farming is widely considered to be a far more sustainable alternative when it comes to food production. The lack of pesticides and wider variety of plants enhances biodiversity and results in better soil quality and reduced pollution from fertilizer or pesticide run-off.
Do organic farmers use more pesticides?
Organic agriculture limits pesticide use as much as possible, using it only as a last resort. And for toxic products such as copper sulfate, organic also limits the amount used to 6 kg per year per hectare. All this means a lower use of pesticides and, therefore, fewer residues.
Is organic a sham?

What are bio-pesticides used in organic farming?
This study to h omemade bio-pesticides used in organic farming. Pests are classified as ‘major’ or ‘minor’ depending upon the extent of damage they cause in any particular ecosystem.
