Whiteflies are a major threat in glasshouse . For feeding , they directly harm plants by perforating leafage , and indirectly they can communicate viruses and make an optimum feeding reason for molds . The tent-fly quickly develop resistivity against pesticide chemicals , which may also affect the natural predators of the fly . biologic control with for exemplar Encarsia and Eretmocerus parasitoids wasps is possible but requires right management of a complex and finespun balance .
Intra Eco Shield is a fluid nutritional flora enhancer that hold a unequalled formulation with a eminent tightness of works - available orthosilicic acid . It physically hardens the industrial plant and better its water and calcium management , make the plant more resistant to stress billet . The effect of Intra Eco Shield was assess on whitefly infection at the horticulture enquiry center of Botany Group ( Horst - Meterik , The Netherlands ) .
pragmatic trial run countersink - upThe test was performed in a greenhouse with tomato plant representative for commercial-grade production ( design 3 ) . On day 13 after exercise set - up , whiteflies ( Trialeurodes vaporariorum ) were preface in the greenhouse . Foliar app of Intra Eco Shield 500 ml per hectare was performed preventative on twenty-four hour period -11 , sidereal day -6 and day -1 before infection , and post - transmission on Clarence Day 6 , day 13 , solar day 20 , and day 27 ( tabular array 1 ) .
hebdomadary evaluation of whitefly reproductive memory was started 13 days after infection . To follow the whitefly aliveness rhythm from egg to hatched pupa , 25 foliage punches ( ø1.5 cm ) were taken at leaves at the same meridian at each time point . In the hebdomad of the last app of Intra Eco Shield , the judgment was finish .
anatomy 2 cater an overview of the total identification number of whitefly eggs , crawlers , larvae , pupae , and hatched pupae per 25 leaf punches of untreated controls and after Intra Eco Shield treatment at three - time points after infection . The total number of eggs and crawlers did not significantly differ between treat and ascendence plants , but treatment with Intra Eco Shield result on day 27 post - infection in a 58 - 67 % decrease in the total routine of larvae , pupae , and hatched pupa . These data point indicate that flies did not make out between handle and untreated flora to place their eggs , and intervention did not dissemble the crosshatch of the ball , but the bit of crawlers that transitioned to larvae was significantly reduced . This indicate that Intra Eco Shield discussion impaired the development of the crawlers , probably by hardening the industrial plant leaf to forestall crawler feeding .
design 2 : Whitefly biography cycles/second and share reduction on twenty-four hours 27 with Intra Eco Shield . The graphs show the total number of whitefly eggs , crawlers , larvae , pupa , and hatched pupea per 25 foliage punches of untreated control ( puritanical bars ) and after Intra Eco Shield discussion ( green bar ) at three time points after contagion .
The use of Intra Eco Shield in whitefly controlOnce - a - calendar week preventive app of Intra Eco Shield on tomato industrial plant breaks the whitefly life sentence cycle and reduced the whitefly development into grownup with 67 % . This suggests that leaf solidification by Intra Eco Shield prevents crawlers from feeding , causing their starving . No spraying remainder were observed after app , since Intra Eco Shield does not contain any smarmy or greasy ingredients , and no phytotoxicity was observed . The natural ingredients of Intra Eco carapace are not harmful to other being , making it potential to compound the plant strengthen lotion of Intra Eco Shield with biologic approaches . In this way , Intra Eco Shield reduce the pest load , thereby make biological control easier .
