Siltac EC – an alternative, physical method of eliminating pests of crop plants

How does Siltac EC work?

Siltac EC is an innovative solution designed to provide an effective method of controlling herbivorous insects and mites that feed on crop plants. The product does not contain traditional active substances of chemical pesticides, therefore it does not require a pre-harvest interval. This makes plant protection much safer.

The mechanism of action the product against insects and mites is typically physical and is based on the unique 3D-IPNS ™ technology (Three-dimensional Immobilizing Polymeric Net Structure).

All ingredients of Siltac EC (all monomers contained in silicone copolymers of which the product is composed) satisfy the registration conditions that apply to such compounds, as required by Regulation (EC) No. 1907/2006 of the European Parliament and of the Council of 18 December 2006.

Siltac EC - product

Benefits of use

  • High effectiveness

    It shows high effectiveness in reducing populations of many troublesome pests of crop plants, for example spider mites, aphids and scale insects.

  • A wide range of applications

    Due to the wide range of use, it is very useful in protecting crops for which there are no registered, traditional insecticides/acaricides for controlling pests.

  • No pesticide residues in plants

    The product does not contain any active substances of pesticides (therefore, it does not leave any residues of plant protection products). It meets public expectations concerning safe plant protection.

  • Pests do not develop resistance to the product

    It is especially effective in combating pests which quickly develop resistance to traditional insecticides and acaricides, such as aphids and spider mites.

  • It controls a wide range of pests

    Due to a purely physical mechanism of the product action, pests do not become resistant to Siltac EC is very useful in anti-resistance strategies and in combating pest populations that are resistant to traditional zoocides.

  • It improves effectivenes of insecticides

    It is suitable for use in combination with plant protection products, improving the pest-control effect. Such combined use enhances the effect of both Siltac EC and a traditional agent.

Note: before applying pest control treatment, please read and strictly observe the notes and precautions regarding the use of Siltac EC!

Recommended dilution rates

Fruit trees and berries

Controlled pests: aphids (including woolly apple aphids), spider mites, rust mites,  scale insects, blackcurrant gall mites, psyllids.

Recommended dilution rates:
0.12% – 0.15 % (120 – 150 mL of the product per 100 L of water)

Recommended amount of water:
500-800 L/ha

When applied in early spring, Siltac EC is very effective in eliminating the European red mite.
The procedure should be performed when larvae hatch from overwinter eggs:

  • apple tree – at the stage of between green buds and pink buds.
  • plum trees – at the stage of green buds.

In order to control blackcurrant gall mites, Siltac EC should be used during the migration period of this pest – from the beginning of the growing season until the stage immediately following the blooming period (2-3 treatments applied at intervals of about 7-10 days).

During the flowering of blackcurrant bushes, the product should be applied at a concentration of 0.1%.

Notes (restrictions in use):
In the case of apple and pear trees, in order to avoid any damage to plants, treatments should be applied in conditions allowing for fast drying of spray solution on plants (e.g. in dry weather, in daytime or on a dry evening).

A drizzle or light rain within 8-10 hours after the spray may increase the risk of phytotoxicity, especially for leaves of pear trees and fruit of apple trees.

Plants in bloom stage – in some species, the product may cause damage to flower petals.

THE PRODUCT SHOULD NOT BE USED IN HONEYBERRY ORCHARDS.

Ornamental plants

Controlled pests: aphids, spider mites, scale insects. Suppression of whiteflies, thrips.

Recommended dilution rates:
Ornamental trees and bushes: 0.1 % – 0.15 % (100 – 150 mL of the product per 100 L of water)
Roses: 0.1 % (100 mL of the product per 100 L of water)
Other species of ornamental plants: 0.05 % (50 mL per 100 L of water)

Recommended amount of water:
The amount of liquid to be used depends on the size of plants. Use sufficient spray volume to ensure thorough coverage of plants.

Notes (restrictions in use):
To protect the leaves of sensitive varieties of crop plants against the risk of burns, Siltac EC must be used when in conditions allowing for fast drying of spray solution on plants (e.g. in dry weather, in daytime or on a dry evening).

Crops in bloom stage – it may damage petals in some species.

It may cause damage to the leaves of geraniums, gerberas, chrysanthemums and of other plants with delicate leaves.

Before using the product:
IT IS NECESSARY TO PERFORM A PRELIMINARY TEST ON A FEW PLANTS TO CHECK POSSIBLE PHYTOTOXICITY.

Tomato, pepper, aubergine: 0.05% – 0.07 % (50 – 70 mL of the product per 100 L of water).

Recommended amount of water:
The amount of liquid to be used depends on the size of plants. Use sufficient spray volume to ensure thorough coverage of plants.

Notes (restrictions in use):
To protect the leaves of sensitive varieties of crop plants against the risk of burns, Siltac EC must be used when in conditions allowing for fast drying of spray solution on plants (e.g. in dry weather, in daytime or on a dry evening).

Notes and contraindications

Notes concerning the use of Siltac EC
  • Siltac EC is sprayed onto plants as a water dilution.
  • Siltac EC should be used when the first colonies of pests appear. If necessary, treatment should be repeated after about 5 – 7 days or later, when pest colonies appear again.
  • Siltac works only through contact action. Good spray coverage of all plant sites where pests are feeding is necessary for control. In the case of spider mites, it is important to spray the both sides of leaves.
  • Siltac EC works only when it is applied directly onto pests that feed on plants.
  • Pests do not develop resistance to the product, because of it's physical mode of action.
  • It can be used every year, many times during a season without losing any of its effectiveness. It doesn't have residual activity. For this reason Siltac EC is not used as a preventive product. In the case when the product is used frequently, an interval of at least 2 weeks must be maintained between the third and the fourth treatment.

 

Precautions
  • The product was tested in terms of plant safety only on some crop species and varieties. Therefore before making widespread applications for the first time in new conditions or to new crops treat a limited number of plants and observe for phytotoxicity. It is especially recommended for ornamentals.
  • In the case of ornamentals and vegetables - DO NOT use the product on plants in their earliest stages of development, e.g. on seedlings) due to a high risk of foliage injuries.
  • In the case of vegetable crops, an interval of at least 7 days should be maintained between treatment with Siltac EC and application of herbicides.
  • In the case when the product is used frequently, an interval of at least 2 weeks must be maintained between the third and the fourth treatment.
  • Do not use the product when rain is expected within several hours (4 - 5) after treatment.
  • The product must not be mixed with any wetting agents, adjuvants, etc.
  • The instructions for use must be strictly followed. DO NOT EXCEED THE RECOMMENDED DILUTION RATES.
