The intensive production of strawberries coincides with the development of plasticulture in Algeria, in 1989 for the wilaya of Tipaza. Strawberry cultivation was launched on an experimental basis in Jijel in 2001-2002, on a four (4) hectare surface area. Today two (2) wilayas TIPAZA and JIJEL on the sidelines of the traditional wilaya of SKIKDA, share the strawberry market, the intensive cultivation of which covers approximately 1,200 ha.
Like any living being, the strawberry plant is subject to various attacks from parasites, diseases and pests, among which we will mention the most important;
Spider Mites (Tetranychidae)
Caused by small spiders barely visible to the naked eye, preferentially localized on the underside of leaves, the attacks of mites causes a yellowish gray appearance to the foliage which dries up, causing a slowdown in the growth of the fruit.
In case of severe infestation, the foliage is covered with webs. The twospotted spider mite Tetranychus urticae is considered the most harmful species on strawberries.
Thread-Footed (Tarsonemid) Mites
These small transparent or yellowish mites are cell-emptying biters but do not weave webs.
Their stings cause the stunting of plants (dwarfism) characterized by the yellow tint of the young leaves which remain small and wrinkled.
Integrated Control
- Be very vigilant about changes in the color of the foliage.
- Practice a reasoned chemical control based on the choice of appropriate products (ovicide, larvicide, adulticide) according to the stages of development of the mites.
- Alternate products from different chemical families.
- Frequently monitor mite populations.
Tarsonemids attack
Uproot and burn plants with more than one leaf in 5 affected.
FLORAMITE 240 SC
- Recommended at a dose of 0.4 L/ha. Volume of the mixture = 1000L/HA.
- Used at the rate of two treatment sequences per year.
- In order to optimize the effectiveness of FLORAMITE 240 SC, complete coverage of the plant (upper and lower surfaces of the leaves) is essential to best reach the mites.
- Alternate FLORAMITE 240 SC treatments with other products with different modes of action, such as the ZORO product, active ingredient ABAMECTIN 18g/L. The recommended dose is 500ML/HA.
The interval between two treatments must be seven (07) days.
