most dangerous pests of strawberries - strawberry mite, strawberry and stem nematodes are distributed mainly to the seedlings.A radical way to deal with these pests - it thermotherapy (treatment of plants in hot water).processing modes are as follows: anti-mite strawberry seedlings should be placed in water at 45-46 ° C for 13-15 minutes;against strawberry nematode - a temperature 46-47 ° C for 15 min;and it requires a strict regime against stem nematode - 47-48 ° C for 15-20 minutes.

plants do not need to warm up when they grow up, and in a state of rest.To do this, we can proceed in two ways: to prepare the seedlings in late autumn, winter to keep it at a temperature of 0-2 ° C, and in the spring, before it will begin to move into growth, heat the water at the right time.Or (the second option) to harvest, iedig up the seedlings in early spring is also at rest and immediately warm.In these cases, after thermotherapy plant waste will be less.

as warm baths can be used at home any large pot or bucket, p

ut them on any heat source (stove, electric or gas stove).To monitor the temperature of the water is better to take a mercury thermometer with a scale interval 0.1-0.5 ° C.Possible fluctuations in temperature during heating ± 0,5 ° C. unusual advice .Warm temperature accuracy can be improved seedlings by using a container of flowing water a predetermined temperature.

thermotherapy technique consists in washing the seedlings with roots (if the plants are decontaminated by stem nematode), heating at the selected mode and immediately cooled at a temperature of 10-15 ° C for 15-20 minutes to relieve heat stress.The ratio of water to the number of plants should be 1: 2.

In the case of disinfection of strawberry mites and nematodes strawberry seedlings are not necessarily completely immersed in hot water - enough to warm the aerial parts (horns and young leaves) and roots (even with a lumpland) leave outside.It will also increase the yield of the plants survived after thermotherapy.Such plants will serve as a masterbatch.
