In June 2018 , Biobest Nederland perform an online survey of 141 Nutrimite users from the Netherlands . Biobest introduced Nutrimite , a food supplement free-base on Typha pollen , onto the marketplace in 2013 . The product perk up the population growth and improves the statistical distribution of predatory mites throughout the craw .
One third of user in the Netherlands participated in this study . The majority of those questioned practice Nutrimite for supplementary eating of A. swirskii , follow by A. montdorensis and , in third place , A. degenerans . In the Netherlands , Nutrimite is used primarily in fresh peppers , potted plants , cucumber and cut flower craw ( see graph ) .
Survey resultsEighty - two percent ( 82 % ) of the Nutrimite substance abuser were satisfied with its effects . The bulk of Nutrimite exploiter argue that the predatory mite universe in their crops increased by 25 % or more as a solution .
When we focalise in on the crops in which Nutrimite is most normally used in the Netherlands , such as sweet peppercorn , we see that 90 % of current user were slaked with the result . Here Nutrimite is in the main applied in the first two to six weeks of cultivation and responder signal that the introduction of the predatory mites ( chiefly A. swirskii and A. degenerans ) as well as the spraying of Nutrimite were considered to be relatively wanton to very easy .
Potted plantsIn potted plant life cultivation , 66 % of those taking part in the view supplemented their predatory mites with Nutrimite . In the bulk of these cases , the predatory mites ( primarily A. swirskii and A. montdorensis ) were given the supplement every 14 days . The potted plant growers rated distributing Nutrimite as comparatively easy to very easy .
CucumbersOf the eight Cucumis sativus growers who complete the survey , six were supplement with Nutrimite at the fourth dimension of the survey . The other two had already discontinue , since their growing season had ended . All drug user question were very satisfied with Nutrimite and had seen their swirskii population increase by 25 % . The approach varied from grower to grower with some supplementing only during the first two to six weeks ; others supplemented every 7 or 14 Clarence Day .
The spraying of Nutrimite and the distribution of the predatory mites was denounce as being comparatively easy to very slowly .
burn flowersThe bulk of cut flower growers survey give supplemental feeding to the predatory jot population . In most case , the predatory speck ( mainly A. swirskii and A. montdorensis ) were give the supplement every 14 day . However , several growers only supplemented immediately after introduce the predatory mites . raiser saw between 15 % and 75 % growth in the predatory mite universe when they used Nutrimite and , generally speaking , were very satisfied with this performance . The most noteworthy reason that growers stopped using Nutrimite was that the predatory mites had sufficient target available to them in the summertime season . As a result , the need for supplementation was significantly reduced .
Rose growers indicated that while it was difficult for them to express in bit the impact of Nutrimite on the E. gallicus population , they were generally speak satisfied with the product .
Vegetable seed productionFinally , one sketch responder conveyed a prescribed experience using Nutrimite in the seed yield of assailable - field veggie . This agriculturist , who apply Nutrimite on a hebdomadary ground , witness his swirskii population addition by an average of 20 % and was extremely quenched with the result .
