6 key steps to safeguarding Sweet Peppers in Murcia
Your step-by-step guide on how to defeat aphids, thrips and spider mites in Spanish peppers
January marks the month sweet peppers officially begin their growing season in Murcia in Spain. Given the Government of the Region of Murcia reported Murcia’s peppers exports reached 100 million Euro in 2013 (41% more than in the previous year), the pressure growers face each season to continue bettering the number of high quality and nutrient rich peppers that predominantly feed the European Union is expanding.
With this weight in mind, we decided to speak to our IPM technical specialist based in Murcia to provide you with some valuable hints and tips on how to optimise biocontrol in your Murcia sweet pepper growing strategy for 2018.

1. START CLEAN AND MONITOR WITH STICKY TRAPS
Start with the greenhouse disinfected, free of rest of crops and weeds. Put 1 blue sticky traps/100 m2 for testing and capture populations of thrips in the first states of the cycle. Remove and replace plants affected for TSWV.
2. USE AMBLYLINE IN EARLY PLANTATIONS
Release Amblyline (Amblyseius cucumeris) sachets ( 2500 sachets/ha) 5-6 weeks after planting with the first flowers to maintain protected the young plants against the thrips. Introduce Swirskiline from February.
3. ADD SACHETS 5-6 WEEKS AFTER PLANTING
Release Swirskiline (Amblyseius swirskii) sachets 5-6 weeks after planting with the first flowering or 6 weeks after Amblyline.
4. APPLY ORILINE
Apply Oriline (Orius laevigatus) 2 weeks after Amblyseius application at rate of 3 ind/m2
5. IMPLEMENT APHID CONTROL
Add Aphiline (Aphidius colemani) to combat aphids (Myzus persicae & Aphis spp.), 0,25 ind/m2x5
6. DON’T FORGET RED SPIDER MITE TREATMENT
Preventive application of 400-1000sachets/Ha of Californiline on the risky areas of the greenhouse (usually close to paths and edges) is recommended. Add Phytoline 5-10 ind/m2 from presence of red spider mite (Tetranychus urticae).
