Very effective product.... but.... By Elizabeth Hitchens 5 1st October 2012

I am a professional horticulturist. Took too long to arrive, (I was told it was in stock) so had to spend much time spraying with SB Plant Invigorator in order to keep infestation suppressed until predatory mites arrived. I was away when product finally arrived,"but not to worry, it will come with instructions" I told my clients.....it didn't! So I had to go in on my time off to apply the mites.

Worked well By Anonymous 4 25th September 2012

Most importantly, the product worked well, although I needed three applications (rather than 2) to get good control in my conservatory. None of my plants has died from spider mite this year. Slight negatives are that the hole in the top of the pot it comes in is too small and it takes ages to apply unless you cut the top off and that the sawdust makes a mess of everything. Particularly if you apply three doses of sawdust. Is there a less durable media you could pack the little mite in?

Good product, poor despatch and poor customer supp By Anonymous 1 31st July 2012

Bought this product for my polytunnel, took 11 days to arrive, by then cucumber plant was dead from infestation. There were no instructions for use when the product arrived. Website said 3-5 day delivery. I rang customer services who said they had to order it in from another company and this is only done once weekly, this should have been noted on website which it wasn't ,however this has now been added to the description, but this did not help me. I would have expected an apology but none was f

RED SPIDER MITE

Order; Arachnida

Family; Tetranychidae

Symptoms

The red spider mite (tetranychus urticae) is distantly related to small spiders, which they resemble. They are a common pest and their presence is indicated by a very fine light speckling or as localised pale yellow spots on the upper surfaces of leaves. Extensive damage is caused to leaves, buds and flowers and leaves will eventually becomes bronzed – in severe cases, leaves may even wither and die. Examination of the underside of leaves with a magnifying glass should reveal colonies of red mites with minute spherical eggs. In extreme cases which remain untreated, greenhouses and house plants may be covered by masses of mites and webbing which they spin. Damage may occur at any time of year under glass, and strawberries, peaches, nectarines, cucumbers, tomatoes, cacti, carnations, fuchsias and poinsettias are at risk, although mites will attack almost any plant.

Description and Life Cycle

Adult female mites are about 0.5mm long and the males are slightly smaller. The mites are usually yellow or green with darker green markings, although hibernating females turn bright red when they stop feeding in autumn. The female mites live for a month or more and lay up to 100 eggs each, on the underside of leaves. These eggs hatch after 3-30 days depending on the temperature, and the six-legged larvae pass through two nymphal stages before developing into adults – at 26.5 degrees centigrade, this will take only 8 days. Breeding is continuous throughout the spring, summer and early autumn when the females stop laying eggs and seek places to hibernate.

Biological Control Treatment

Accidentally introduced from Chile on a shipment of orchids in 1958, phytoseiulus persimilis is a fast moving predatory mite and the principal biological control for greenhouse red spider mite. The adult phytoseiulus are slightly larger than the spider mites with longer legs and an orange-red body. They move rapidly over plants, searching for they prey and each individual can consume 5 adults or 20 immature stages of spider mite per day. The secret of phytoseiulus’ success is simple; it’s development from egg to adult is twice as fast as that of the spider mite at 20-22 degrees centigrade, although the predator does have a problem moving from plant to plant; leaves that touch provide a transfer from one plant to another, and where this is unpractical, the use of string or netting to provide a miniature walkway is advised. This predator is capable of totally eradicating red spider mite infestations but there is a negative to this positive; the phytoseiulus will die out from starvation and will need to be reintroduced if new spider mite infestations occur.
