The invention relates to agriculture, in particular to adhesive compositions used for the destruction of pests in gardens, and, preferably, for winter grounds, to determine their number, and can be used to predict protective measures.

The aim of the invention is to increase the stability of sticky properties, elasticity at low temperature and high humidity, the efficiency of trapping,

As a modified rosin, the composition contains a partially esterified glycerol or disproportionate rosin containing neutral rosin oils of 10-12%.

Partially esterified rosin is produced by heating pine rosin (gum, extraction or tall) with glycerin (1% by weight of rosin) at 200-260 ° C for D-5 h. The product contains 10-12% neutral rosin oils,

Disproportionated rosin is obtained by heating rosin at 270 g, at 2.5 hours in the presence of a calcium iodide catalyst (0.3% by weight of rosin). The disproportioned grandchild rosin is also used without distilling off neutral rosin oils.

The polyterpenes used are a product of the polymerization of terpenic hydrocarbons, which are part of gum, extraction or superegonic scapidar, with a degree of polymerization of 2-A and mol.m. 280-300.

Polyterpenes are oily transparent oil, light yellow in color with a density of 0.94 g / cm and a viscosity at 20 800 800–900 cSt.

The oxidized polyethylene wax OPV-40, which is a part of the proposed composition, is obtained by oxidation of polyethylene -o-wax PV-25.

VM-1 vacuum oil is used as a solvent for the preparation of the adhesive composition.

The adhesive composition is prepared as follows.

In the mixer, equipped with a stirrer and heater, load the estimated amount of crushed rubber. Then the solvent is loaded, modified

After the melting of the rosin (), the mixture is stirred for 2 hours until a homogeneous composition is formed. The adhesive composition is determined visually. The resulting glue is light brown or brown in color. the low odor characteristic of resins and mineral oils is easily applied to the substrate (paper) in a thin layer, does not flow from it. The method for preparing the composition is simple and does not require special equipment.

Example 1. 5% by weight of crushed rubber and 25% by weight of polyterpenes are loaded into the mixer and mixed at 135 ° C until the rubber is completely dissolved. Then the mixer is switched off, 35% by weight of partially esterified rosin containing 10–12% of neutral rosin oils is loaded, after melting the rosin 10% by weight of polyethylene oxidized wax and 25% by weight of vacuum oil VM-1 and ne - Remiv; mix the mixture for 2 hours to form a homogeneous composition.

NOTE 2-14. The adhesive composition is prepared analogously to example 1 using pine gum rosin.

In tab. 1 shows the compositions of examples 1-14 (examples 7-14 - control).

In tab. 2 shows the results of laboratory tests of the adhesive composition of examples 1-14 and the adhesive composition of the prototype.

The tests are carried out as follows.

Pa substrate (parchment paper 100x250 mm) is applied with a thin layer of glue, evenly distributed over the surface, and tested under conditions as close as possible to operating conditions (temperature from -5 to and air humidity 97.5%).

Examples The adhesive composition is prepared analogously to Example 1, using extraction and tall rosin.

In tab. 3 presents the compositions of examples 15 and 18, and in table. 4 - their properties.

Samples of the adhesive composition (examples 1 and 4), which showed good performance properties (stickiness,

elasticity and stability when tested in laboratory conditions, tested in the field, then under production conditions on the efficiency of catching winter butterfly butterflies. The trials were carried out in a fruit bearing common blond garden for 3 years during the mass summer of butterflies of the winter peak in October.

Blons were laid on the parchment paper 20 x 70–80 cm (depending on the tree diameter), tied up with a string and put on a thin layer of glue, evenly distributed over the paper surface. Consumption of glue 60-70 g for one s. For 6 days, on average, 196-322 butterflies of the winter n stuck on each of them. With a square tree planting scheme (156 trees per 1 ha), more than 31,200 pest butterflies were harvested per hectare per hectare. Its wintering stock in the garden has been greatly reduced by this technique.

The results of catching the winter penny butterfly on glue in sa in the blond garden are given in Table. five.
