What is Limonica?
Limonica is the trade name used by Zonda Beneficials for the predatory mite Amblydromalus limonicus.Limonica is used to control spider mite, thrips and whitefly. We have also seen good results in Psyllid control early in the season when infection pressure is not too high. It can be used in a wide range of salad and ornamental crops, except tomatoes as the hairs on the tomatoes hinder the mite.
Limonica is beige-pink in appearance; it reproduces quickly in humid conditions and in the presence of prey.
How does Limonica work?
Limonica is a generalist predatory mite, effective in the reduction of spider mite, thrips, psyllid and whitefly. It is also known to prey on broad mite. Limonica is a highly active predator, consuming more thrips per day than any other well-known predator mite. Limonica targets the eggs and all larval stages, hunting their prey or waiting for it to pass by before sucking it dry.
As Limonica also feeds on pollen, they can be introduced and established in to some crops before the appearance of pest mites.
Limonica does not enter diapause and can therefore be introduced in winter. Although still being effective at temperatures as low as 13˚c, Limonica perform best at temperatures between 25˚c and 30˚c.
How is Limonica supplied?
Limonica is supplied in 1L bottles. Each bottle contains min. 12,500 predatory mites and is mixed with millet husk, bran and sawdust. Limonica will need to be carefully sprinkled on to the leaves of your crop, evenly distributed over the total surface area. Make sure the material remains on the leaves undisturbed for some hours after introduction. It is strongly recommended not to carry out any work in the crop in the hours following application.
Limonica should be introduced when low levels of thrips or whitefly are present. As pest populations can grow rapidly, it is always best to introduce Limonica as soon as possible. Limonica also develops on pollen so; preventative introduction is possible from the moment crops flower continuously, (i.e. in sweet pepper crops).
Limonica are sensitive to low humidity, so misting systems can be very beneficial in hot, dry, summer conditions.
Preventative / Previous introduction – 2 x bottles/ ha
Low infestation – 5 x bottles/ ha
Heavy infestation – please contact us for more information and best course of action
Storage and Handling
Once received Limonica, can be stored for 1-2 days in a cool, dark place at between 12-14˚c.
Biological beneficials should be introduced into the crop as soon as possible after receipt.
The ideal environmental conditions for Limonica are:
- Relative humidity greater than 70%
- Temperatures above 20˚c for some hours of the day. Optimal temperature is between 25-30˚c.
Temperatures above 35˚c have a negative influence on the development of Limonica. Therefore, Limonica do not generally perform well under very dry and hot conditions.
Before introducing Limonica to any crop it is very important to consider what insecticides or fungicides have been used in the crop within the last two months. Many chemical sprays can have a long lasting residual effect on biological control agents. There is a limited number of chemicals that can be used in a crop when using beneficial mites. Please check the compatibility of certain chemicals before introducing any beneficial. Please refer to the Koppert Side Effects Guide – www.koppert.com/side-effects/.
