At HortiPro , they let the cat out of the bag about ‘ intensive control ' . And that ’s incisively what it is . It ’s not done covertly . But because of all kinds of sensitivity also not explicitly . There ’s a bit more to it than that . Say you have a clear idea of what pests are present in your craw . These could be red wanderer tinge , whitefly , or thripid . And you experience how these populations will develop . Then you could anticipate this in your crop protection strategy . And prediction agency improved , more effective use of pesticides . And , so , you deliver money while becoming more sustainable .
Eric Kerklaan ( tie-in ) and Leon Breugem .
Generally utter , you could reach that by using the correct pheromones . This method is always being developed . And it ’s gradually put on ground in horticulture . Leon Breugem of Breugem Plants is someone who ’s benefited from this . He grows tail-flower in the Netherlands .
Thrips can be a pain in the neck for these kinds of blossom . That ’s the Californian ( Frankliniella Occidentalis ) but peculiarly the so - shout pepper ( Thrips Parvispinus ) thrips . you could control most thrips with nematodes . However , these worms do n’t have much issue on Madagascar pepper thrip . If these thrips look , there ’s nothing else to do than to chasten selectively .
Tactic
But , a architectural plan was hatched with Eric Kerklaan of HortiPro ’s help . They hung several muggy traps throughout Leon ’s greenhouse . Some are fitted with a ' capitulum ' , a small tube containing non - selective thrips pheromone . This kernel is a specific ' sex substance ' . But it ’s been develop in such a way that both males and female are attracted to it .
These sticky traps should therefore pull significantly more thrips than the standard sticky ambuscade . And indeed , the divergence are vast . The two military personnel have been matter how many of these critter are caught and comparing the results . They ’ve been at this every week for more than a year .
This control method go to several conclusions . foremost , it hold a more up - to - escort , accurate picture of the current pestilence development . A particular cuss may or may not be present . Its numbers may be declining or increasing . And that may be at a temperate or alarming charge per unit . interpret that to Breugem Plants ' office . Leon could , for illustration , found that a little pepper thrips universe was maintaining itself throughout the winter .
He was also capable to make a more targeted assessment of when to deploy additional / new biologic controls . These controls let in Steinernema Feltiae nematode worm against thrips . And Aphidoletes Aphidimyza aphid midge against aphid . They then had more time to establish themselves and go to work . And spray with chemicals could part or even altogether be pretermit . If the chemical correction was of a sudden require , in the spoiled case , Abamectin was go for .
Improved industrial plant quality
The tribulation has been run for more than a twelvemonth . It ’s , of course , a erudition curvature . But Leon ’s already convinced of this method acting ’s effect and utility . " At time in the past , the pest pressure level was mellow . Then we ’d have to trim down several leaves from the works . That takes workplace , and it significantly lowers the plant ' timbre . Since we ’ve been doing the pheromone controls , we ’ve not had to do that . "
Eric , too , is proud of with the trial results . " There are few sticky sand trap . They , therefore , really only serve as an indication . However , establish on that data , the grower has already go through pronounced improvement in his harvest . He ’s using substantially few pesticides too . For us , it was also interesting to map out the wave practice . And to be able to conclude that our finding result to respectable results . That ’s combined with our shared knowledge of pest exploitation and control , " he close .
