Koppert’s nematodes offer effective biological control against this pest.
The common asparagus beetle, a pest that specifically affects this crop and that can cause serious damage to the fruit, now has a complete biological control protocol available, developed by Koppert Biological Systems to guarantee an effective fight against this insect using 100% natural, residue-free solutions.
This protocol is based on the use of Capirel®, formulated with the entomological pathogenic nematode Steinernema feltiae. Capirel® is a biological, 100% natural insecticide that is authorised for ecological farming. It uses foliar application, from April to July, coinciding with the two larva cycles that the common asparagus beetle develops each year.
The nematode that contains Capirel® is highly effective against the common asparagus beetle larvae (Crioceris asparagi). Both adults and larvae of this pest feed on the asparagus leaves.
The Capirel® nematodes find the larvae and they infest them, entering them through any of their natural orifices. When the micro-organism is inside the larvae, it feeds on it and reproduces.
Depending on the pressure of pests, a second application of Capirel® is recommended one week after the first application. The product is very simple to prepare and its significant dissolution capacity makes its application much easier. Capirel® has a shelf life of four months from the packing date and it must be stored in a suitable place with temperatures of between 2 and 6 degrees.
In addition to Capirel®, Koppert recommends the use of Trianum® to naturally stimulate the plant’s growth, preventing the appearance of soil pathogens and contributing to the biological control of the common asparagus beetle. Trianum® is a biological fungicide formulated with an exclusive strain of Trichoderma harzianum.
