Among the many things you have to consider when adjudicate what and how to spray to regale a plague or disease on cosmetic harvest are where the problem occurs on the plant life ; whether you may target it immediately with your program ; and whether or not you require some ‘ residual ’ activity within the plant .
Some insecticides , for case Syngenta ’s Hallmark Zeon ( lambda - cyhalothrin ) * , are only effective when in contact with the pest . But some pests , such as glasshouse spider mite ( also known as the two - spotted spider mite ) , thrip and leafminers , are difficult to hit directly with a spray . This is when a ware that can move within the plant after software program comes into its own . Some , such as Dynamec , can go comparatively short distance , for instance from the upper to lour leaf surface ; others can go further .
study how industrial plant protection products move within a plant – biokinetics – is an authoritative part of how we contrive and acquire new products but screw a little more about it can also facilitate you get the right from your applications .
The three biokinetic pathwaysIt ’s important to remember that when we talk about striking , translaminar and systemic activity , it only describes whether or not the product moves within a plant after it has been applied . That ’s quite separate from its ‘ mode of action ’ which , as we ’ve visualise in previous blogs of Syngenta , is the specific chemical substance reaction or physical mechanism by which a product terminate the target pest or pathogen .
tangency productsThe active center stay only on the sprayed surface of the flora . It must come into contact with the pest or pathogen to practise ascendancy .
professional : If the plague or infection is restricted to the works ’s surface , the aerofoil is all you postulate to treat .
Cons : Areas out of reach of the spray are unprotected , as are any new shoots or leaves that acquire after an software ; and there is limited or no ascendency of those pests or pathogen that spend part or all of their life - cycle within flora tissue paper
Art of lotion : Good app proficiency and addition of adjuvant to spread the nebulizer on the plant surface will optimise performance .
Translaminar ( also known as topically systemic ) productsThe active substance inscribe the plant tissue where it remains locally as a ‘ source ’ , affecting pests feed or pathogen produce on or within that tissue . The term translaminar comes from the substance ’s power to move within leaf tissue from the upper sprayed airfoil to the low surface .
pro : The active nitty-gritty come into inter-group communication with pests or pathogen living in punishing - to - reach parts of the plant such as the underside of leave , and inside shoots and flower buds , as well as within industrial plant tissue paper .
confidence trick : The active substance can not spread through the whole plant so any new shoots or leaves that grow after an program will be unprotected .
Art of software : These mathematical product , which include Syngenta ’s insecticide Dynamec , tend not to leave long - lasting residues on sprayed surfaces so fit out well into IPM programs .
Systemic productsAbsorbed by foliage or root tissue , the fighting substance infix the vascular organization within which it ’s transported to other parts of the works . It travels in the xylem , which impart weewee up from ascendant to parting and shoots in the transpiration stream ; or in the bast , which carry the product of its metabolism , such as sugars and amino acids , from where they are made to where they are used and stored .
Pros : The active meat move around the plant life so is more potential to reach land site where pests and pathogen are active , including parts heavy to target with sprays , and new tissue that develops after an app .
con : Fewer systemic product are being authorised because the reservoir of active substance in the works is more probable to involve some good organisms and biocontrol federal agent as well .
Art of app : Systemic product such as Syngenta ’s fungicide Subdue are good candidates for drench app or incorporation in growing medium .
Experienced growers will be running through these full point subconsciously each time they gear up to treat a crop , but it ’s important to check sporadically you are have the product you use every opportunity to lick for you .
Once you know what product you ’ll be using and what you ask to do to maximize control condition , you could align your program program in line with the recording label and the tips in theArt of Applicationseries to get the best potential results .
