Now that really depends on the &#x27;organic&#x27; standards the farmer has decided to follow.<p>The UK Soil Association Organic standards (<a href="http:&#x2F;&#x2F;www.soilassociation.org&#x2F;organicstandards" rel="nofollow">http:&#x2F;&#x2F;www.soilassociation.org&#x2F;organicstandards</a>) are known to be some of the strictest. And section 4.11 on controlling pests and disease makes me very pleased to support organic farming.
