Cotton Aphids: If aphids and beneficial insects are dense in field inspections, application should be postponed. It is recommended to apply when 50% infested seedlings are detected after thinning in the seedling period and when an average of 25 aphids are detected in a leaf in the field period.
Cotton Leafhoppers: In surveys, a 50-da cotton field is divided into 4 sections. Leafhoppers are counted on all 25 leaves, 1 from the lower, middle and upper parts of the main stem of randomly selected plants from each section. In this way, the average number of pests per leaf in a total of 100 leaves from the entire field is found. Application is made when an average of 10 leafhoppers are detected per leaf.
Tobacco Whitefly in Cotton: Considering the density of whiteflies, control should be started when 10 larvae + pupae are found per leaf.
Potato Beetle in Potato: When the daily average temperature reaches 14-15 ˚C, the field is entered from the diagonal direction and the eggs, larvae and adults of the pest are searched in the pits. Encountering any of its stages indicates that the field is infected. If an application is to be made against the first generation, it should be done when the first mature (4th stage) larvae are seen on the plants. In case of application against the second generation, it should be waited for the egg hatching to be completed. Since the damage that will occur depending on the insect density during this period can be tolerated by the plant, application may not be necessary. As a result of the research, the 20% damage caused by the potato beetle on the leaves of the potato plant can be tolerated by the plants and there is no decrease in the product. This rate increases up to 40% depending on the phenological period and development status of the plant. Tomato (field), tomato (greenhouse), cucumber (greenhouse), gherkin (greenhouse), eggplant (greenhouse), pepper (greenhouse) - Tobacco Whitefly and Greenhouse Whitefly: The area detected to be infested with whitefly is entered in the diagonal direction. 50 leaves are collected from the lower, middle and upper leaves every five steps. Chemical control is applied when there are 5 larvae + pupae per leaf.
Pistachio Psyllid: Application should be made when 20-30 nymphs are seen per leaf as a result of weekly counts on 100 compound leaves, when the majority of the eggs hatch and before the first adult parasitoid hatches and before there is a sticky layer (fumagine) on the leaf surface.
Against Cherry Black Aphid in Cherries; Application is made when there are 7 infested branches on a tree between March and October.
Against Peach Aphid in Watermelon; By entering the field in the direction of the diagonals, one leaf is randomly picked from the fresh leaves and shoots of a plant in 3-5 steps. In large-leaved plants such as watermelon, if the number of aphids falling on a leaf is 10-20, application should be started.
Against Green Aphid in Apple; Application should be made when 15 infected shoots are seen in 100 shoots during the vegetation period.
Against Peach Aphid in Tobacco; Application should be started when an average of 25 nymphs + adults are seen on a leaf. Application is made when pests are seen during the seedling period.
Against Pomegranate Whitefly in Pomegranate: In order to determine the application time, the lower surfaces of the leaves on the lower branches are checked and counted as of the beginning of May in spring. If the total number of eggs, larvae and pupae is 10 and above per leaf, application is decided. S. phillyreae reaches the density required for application in pomegranate orchards generally in the second half of May in the Mediterranean Region. However, since the pomegranate plant is in full bloom during this period, applications should be made around the first half of June. A single application during this period is sufficient to combat the pest.
Against peach aphids, applications should be made when 7 infected branches are encountered in 50 trees, from the emergence of flower buds until 3/4 of the population turns into winged form.
