Just got a report from an austrian gardener who treated thrips in Primula obconica successfully. (496)
Ms S. had six cucumbers in her greenhouse ... as every year, they developed well until they were affected by spider mites in June. The affected leaves had yellow spots, caused by the sucking action of the pests, which later became larger, until finally the entire leaf dried out and turned brown ... Ms S. treated the cucumbers with a mixture of Petroleum 30 C and Psorinum 200 C. The spider mite infestation improved a little but then returned strongly again. At this stage the cucumber plants looked distinctly unwell. At the beginning of August, she tried Amblyseius 6 X. She removed the old affected leaves and watered the cucumbers 2x per week with 10 ml of remedy solution in 10 litres of water.
To her astonishment, the cucumbers developed new shoots, with healthy leaves and fruit, right through to the end of September - completely free of spider mites. In previous years the cucumber plants were finshed already in August. (Edda S., Schwaigern 2013) (133)
