MagGrow heeft wereldwijd gevallestudies gedaan om de effectiviteit van onze producten te bewijzen.
Late blight, caused by Phytophthora infestans, is the most important disease in potato production. Under favourable conditions the pathogen can destroy the potato foliage very rapidly and cause tuber blight. To avoid infection of the foliage, fungicides are frequently sprayed onto the crop.
In the Netherlands, in some years up to 15 sprays are necessary to prevent the crop from infection by the pathogen. A field experiment was conducted at the Wageningen University, Lelystad facility to evaluate the performance of the MagGrow system vs conventional spraying methods in the efficacy of fungicide spray programs in their control of potato late blight. This paper is a condensed version of the report that was completed by Wageningen University
This study was conducted in June 2014 by the research institute Proeftuin Zwaagdijk, which is located 50km north of Amsterdam. The goal of the trial was to compare the control of Fusarium Head Blight in Winter Wheat between MagGrow and conventional spraying at varying dose rates.
• The trial plots measured 10m x 3m and each plot was replicated 4 times.
• The application was sprayed on 17 June at growth stage 61 (beginning of flowering).
• On 1 July the ears infected by fusarium were counted (white ears).
• On 5 August the trial was harvested with a combine harvester which is specially designed for trials.
This study was conducted in a field near the Friesian village Nij Altoenea in a region called ’t Bildt. It is a coastal area where a lot of Seed Potatoes are grown. The potatoes are grown for an internationally operating trading company and therefore sold all over the world. Quality is absolutely essential to maintain this market. Disease tolerance in the highest class of Seed Potatoes is zero. The field is 370m in length and for the purpose of the trial one of the tramlines was dedicated for spraying with MagGrow using the Dubex sprayer, with the remainder of field being sprayed by the grower’s conventional sprayer. The grower used XR110-05 nozzles on the entire boom. MagGrow was used @79% rate (XR110-04).
Seed potato SCHuiLING case study
This case study was conducted over an entire growing season in the northern region of the Netherlands, where the majority of Seed Potatoes are grown. The potatoes are grown for supply across international markets, sold to companies all over the world. Quality is essential to maintain the market share and leadership position. Disease tolerance in the highest class of Seed Potatoes is zero.
The farm size is far above average in the Netherlands and around 30% of the cropping plan consist of seed potatoes. The crop was sprayed with Fungicides, Herbicides and Insecticides using MagGrow Technology retrofitted onto a new Agrifac 51 meter sprayer. Previously, conventional spraying techniques used 250 litres of water per hectare, and now with MagGrow Technology the usage has dropped to 200 litres of water per hectare. In addition, the chemical dose has also been reduced to 75%-80% of conventional rates.
In a trial set up on Flamingo Horticulture Naivasha farms, the MagGrow spraying apparatus was compared to Conventional apparatus as presently used on the farms. There was a marked reduction of 20% in spray volume with the use of MagGrow compared to Conventional, while no significant difference in the control of both pest and disease was recorded.
MagGrow is a pioneering, patented magnetic spraying technology system for the horticulture & arable sectors of the agricultural industry. The technology is based upon the premise of attaching magnetic inserts onto a sprayer which imparts an electromagnetic charge into the sprayed liquid. The aim of this trial was to evaluate a targeted volume reduction of 20% in the use of MagGrow Spraying Technology compared with Conventional Application Technology.
Within horticulture and agriculture, pesticide application can be financially intensive practice. Furthermore, increasing environmental concerns have also led to an emphasis on reducing chemical inputs along with other resources such as water. Volumes of pesticide application on high value crops often range in 1000’s of litres per hectare. Therefore, there is increasing interest in methods to reduce such inputs within all sectors of horticulture. As such, this report sought to prove that water inputs could be reduced using patented MagGrow system.
MagGrow was tested at reduced rates, alongside conventional application methods on mature Rose crops grown in two separate glasshouses at Gallica Flowers, Ethiopia from Dec 2015 to Feb 2016. The study applied the use of hose and reel lance as a control and MagGrow backpack products at reduced rates of 60% on the fungal disease Powdery Mildew. MagGrow and conventional plots were sprayed for Powdery Mildew every 3-4 days, using products Meltatox and Impulse at does rates of 21/ha and 1l/ha respectively. Application rates for conventional were 1000l/ha while MagGrow application rates were set at 600l/ha (i.e. 60%). Between each spray, for both MagGrow and conventional, disease scouting was carried out to establish a pre-and post-spray disease level. The pre application and post application Powdery Mildew levels were used to determine results (i.e.% disease reduction)
