A higher weewee volume does not always give better upshot , according to a spray technique test on 12 March for Gerbera polish in combination with Mainspring - an insecticide for land - based decorative plants . The result : spraying with less water often gives similar or better results .
Gerbera jamesonii Cartwheel Strawberry Twist
The amount of pee that can be used in combination with insecticide is being baffle more and more . A demo test was typeset up by Syngenta Netherlands to be able-bodied to demonstrate the possibilities with the current spraying technique . All Gerbera agriculturalist in the Netherlands were invited on 12 March for an info confluence about spraying techniques and to view the trial . The meeting was arranged in coaction with Erik Mooij ( Guidance Crop Protection Greenhouse Horticulture ) and Royal Flowers in Moerkapelle , the Netherlands .
aim of the testThe main aim of the mental test was to see whether the water system bulk can be contract when using Mainspring . To make the results more visible , Helios was used - a fluorescent chemical formula that makes the spray visible under UV igniter .
Various pee volumes were tested on 12 March , browse from 600 to 2,000 liter . Normally , water volumes of 1,500 ltr / ha or more are used in Gerbera polish . The following quantities , fastness and pressure were therefore test :
ResultsThe test showed that there is a higher risk of exposure that the intersection will drip off of the leaf as soon as high water volumes are used . On the objects A and B ( 2060 and 1780 ltr / ha ) was understandably visible that the spray liquid started to float to the edges of the leafage and even partially left the leaf – a so - called run - off .
At the objects C and D ( 1326 and 665 ltr ) the drops did not fall off the plant life , but a good covering of the plant was still visible . An additional vantage is that if the pee mass / ha is reduced by maintaining a high driving pep pill , a considerable amount of time can be saved .
Although it is often preferred to expend more water , cultivator themselves saw under the UV light that more water system is not always well : the intersection is lose unneeded because it drips off the plant . The trial results also show that in many cases a reducing of the spraying book gives in many case similar or even better coverage results , which positively mold the effect of the product .
