Researchers at Cornell University ’s Long Island Horticultural Research and Extension Center ( LIHREC ) are using Svensson ’s Econet 1515 insect control concealment to exclude thrips and other insects from their greenhouse benchtop breeding trials of impatiens ( Impatiens walleriana ) . The Research Center take in peculiar care of plants for sensitive research , keeping these plants in exclusion cages which are lined with Econet , preventing exposure to thripid and other insect that are transmitter for computer virus - borne disease .
Impatiens were formerly one of the most pop annuals for horticulture and landscaping in the easterly US due to the many colors uncommitted , margin to develop in full shade or sun , and accessibility early in the spring season . Although , in 2004 , a new , virulent kind of impatiens downy mildew ( IDM , Plasmopara obducens ) , was identify on vegetatively - propagated impatiens cultivars that were already commercially distributed over a large sphere . The disease unfold quickly throughout the US and worldwide , and from 2009 - 2014 there was a tenfold decline in impatiens sales in New York State alone . Susceptibility is nearly ecumenical within the common impatiens metal money .
Dr. Mark Bridgen leads inquiry efforts at LIHREC to breed an impatiens hybrid that is immune to IDM . “ We have successfully confirm that other impatiens species compatible with I. walleriana were also resistant to IDM and utile for breeding , ” Dr. Bridgen say . “ Cornell University now has 2 lines of impatiens hybrids that are resistant to IDM . The next step is to stay this fostering syllabus and explicate seed - propagate lines of the resistive hybrids . By doing this , we will be capable to fill up the garden niche that has been restrain by Impatiens and put up more options for growers . ”
The Cornell greenhouse where Dr. Bridgen and his staff conduct breeding visitation formerly faced gadfly challenges with thrips ) and other computer virus - carrying dirt ball which need to be 100 % excluded from the intercrossed plants throughout the trial . The Econet 1515 dirt ball censure screen carry off the University ’s plague challenges , providing a secure barrier that excludes harmful insects , including thrip , while still allowing light and airflow to the plants .
“ Econet 1515 was lop over three greenhouse benchtop Al frame to mold dirt ball - free cages where the intercrossed impatiens plants could be grown , ” Dr. Bridgen said . The enclosure host plant life that need to grow in a strictly ensure environment with a guaranteed protection against insects .
He is very pleased with the resultant role of the insect sack up so far and believes it is doing just what it is supposed to do . “ Econet has been working absolutely to keep thripid and any other insects out . It ’s a with child product and has been wonderful for our impatiens . ”
These trial will continue in 2019 , aided in part by the insect ejection that Econet 1515 has provided .
