The activity of the compounds obtained is determined in the fight against insect pests, including ticks and some insects (such as caterpillars, beetles and flies).
Suspensions of test compounds were prepared by dissolving one gram of compound in 50 ml of acetone, in which 0.1 g (10% of the weight of the compound) of an alkylphenoxypolyethoxyethanol type surfactant was previously dissolved as an emulsifier or dispersant. The resulting solution is kneaded in 150 ml of water, yes. Approximately 200 ml of suspension containing 0.5% by weight of the compound in finely divided form. Aphids (Aphis fabaE Scop), intended for experiments in the form of aerial specimens and larvae, are grown in dwarf plants planted in garden nasturiations at 18.321, and 60-70% relative humidity. The number of aphids per pot is standardized at 100,150 by trimming and trimming plants containing an excessive amount of aphids. Compositions containing test compounds are prepared by diluting the base suspension with water in order to obtain a suspension containing 500 parts of the test compound per million parts of the final composition. Plants planted in pots (one pot for one test compound) infected with 100-150 tons of each is placed on a turntable, rotatable, and sprayed with 100,150 ml of the composition tested with the compound. Spraying is carried out with the help of a complete spray gun with compressed air under a pressure of 2.8 kg / cm for 25 seconds, which is sufficient to moisten the plants close to the appearance of flowing drops. As a control, infected and sprayed are also sprayed with 100-110 m of an emulsifier solution in a mixture of acetone and water that does not contain the test compound. After spraying, put the pots in the middle of a sheet of white paper for a meograph, which is pre-graflen to facilitate counting. The temperature and humidity in the test room for a 24-hour exposure period is, respectively, 18.3-21.3 s and 50-70%. Aphids falling on paper and unable to return to their original position, when turned upside down, are considered dead. Aphids remaining on the plants thoroughly settle, observing their mobility. Those who are not able to move for body length after stimulation by adjustment are considered killed. For various levels of concentration, a degree of mortality is expressed, expressed as a percentage. The test results are shown in the table. The pesticidal activity of the compounds at the indicated degree of dosage in relation to tl mites, ticks, chertsev, legume, and houseflies are characterized by the following estimated indicators: A-good lesion results; B-partial lesion; B-inactive or lesion is essentially absent at a concentration of 500 parts per million. Experimental organisms are mature individuals, and individuals in the nymphal (underbone) period of two-tick mites (Tetranychus urtica Koch), bred on soft bean plants at a relative humidity of 80t5%. The infected leaves of the basic culture are placed on the main ones (the primary leaves of the two beans are 15–20 cm high, grown in a clay pot 6.2 cm high. 150–200 mites are sufficient for testing. They are transferred from cut leaves to fresh plants in 24 After a 24-hour transfer period, cut leaves are removed from infected plants.The test compounds are formulated by diluting the base suspension with water so as to obtain a suspension containing 500 parts of the test compound per million parts Plants planted in pots (one pot per compound) are placed on the turntable and sprayed with 100-110 MP of the composition containing the test compound. Spraying is performed using a complete spray gun with compressed air under a pressure of 2.8 kg / cm per million. Experimental plants are sprayed (according to the method for the experiment on spraying the foliage with mites on it, about 100 ml of the test solution. Sprayed and control plants are set aside for about 1 hour to dry the foliage, then they are placed in a greenhouse. After 10 days, the plants are visually inspected to determine the degree of foliage damage using the following estimates: 1 — no noticeable damage; 5-death of the plant. Values 2-4 indicate intermediate damage rates depending on the number of affected leaves and the extent of their damage.
