pherolit®-d

to combat corn rootworm

The western corn rootworm (also known as Diabrotica virgifera virgifera) is the nightmare of all maize farmers. Until 2014, insecticides from the neonicotinoid group were used to keep its spread in check. Following the ban of these pesticides because they are harmful to bees, the problem has intensified out of all proportion.

Our natural solution

We have developed and registered the first ever sprayable pheromone (pherolit®-d) for protecting maize plants by using the naturally derived female pheromone of Diabrotica v. v. for large-scale use on maize crops. Using lithos micro dispenser® technology a carrier allows slow release of the pheromone to bring about seasonal disruption of mating.

How pherolit®-d works

The pheromone pherolit®-d confuses the male beetles so that they are disturbed in their reproductive behaviour. This means fewer eggs are produced in the following year, causing less damage to the maize crop as a result.

Reduces the fertility rate of the pest
reduces root damage in the following season by up to 50%
Effective for up to 8 weeks
targeted and specific effect, harmless to all other living organisms (conserves biodiversity)
Can be applied by all standard field sprayers
Use in conventional and organic farming

Current status of pherolit®-d development

The active ingredient pherolit®-d is currently undergoing EU-wide approval. Applying for approval has involved a large number of studies and field trials being carried out so far. The next step is a product approval. Our newsletter keeps you up-to-date on the progress of our product developments:
