Plant diseases

Asparagus beetles
Crioceris duodecimpunctata=red; Crioceris asparagi=blue

These blue and red beetles lay their eggs on bushes. Its larvae chew at the bushes, causing their stems to turn brown and produce a lower yield in the following year. The damage occurs primarily in the first and second year of harvest. The disease usually begins with an attack on several plants and, then, spreads quickly into other plants.

Asparagus aphid
Platyparea poeciloptera

This dark-coloured fly with light-coloured dots on its wings may be easily noticed in an asparagus field. It is active from late April to early July and produces only one generation within a year. It lays its eggs on the tops of young stems. The larvae chew out holes in the stems, near the ground, and undergo metamorphosis inside them. As a result, the infected stems grow twisted and die prematurely. Aphids are at their most active during hot weather. The risk of infection is reduced through, in addition to the use of insecticides, the removal of bushes for the winter period.

Delia Platura

Delia Platura lays its eggs inside stems during harvest. The larvae chew out holes in the stems, making them inedible. In some years the plants are infected with the insects, in other years they are not.

Asparaguses


GIJNLIM

Gijnlim F1 is a 100% male hybrid and ideally suited for cultivation of both white and green asparagus in temperate climate zones. This variety is an exceptionally early grower and gives very high productivity. Gijnlim is ideal for forced cultivation conditions. This variety is highly valued for direct from farm sales.

Cultivation

Gijnlim performs well on sandy and clay soils. The more fertile the soil is, the later spear thickness will remain good even when the season is advanced. Extensive practical experience has shown that the best results for white asparagus are achieved with a planting density of 3 - 3.5 plants per m1. This plant density can be increased by approximately 30% if the asparagus is harvested green. Higher planting densities give a higher yield, but can lead to an accelerated decrease in spear thickness. Thanks to its natural earliness, Gijnlim is ideally suited for extra forcing techniques, such as anti-condensation sheeting, mini tunnels and thermal sheeting.

Product

Gijnlim has a very high production potential and exceptional quality. The main grade is class 16 -24 mm. Gijnlim has an excellent closed tip, is straight and smooth with high rust resistance. Good post-harvest handling will prevent pink discolouration.

Foliage

Gijnlim has full and heavy foliage. If correct attention is paid to disease control, the foliage remains sufficiently green and strong right into the autumn.

Seeds

All seed supplied by Limseeds is subjected to strict internal quality inspections to test germinating power and varietal purity. Before the seeds are supplied they are inspected and tested again by Naktuinbouw, an independent inspection service regulated by Dutch Ministry of Economic Affairs, Agriculture and Innovation.
