What is Tomato Guidance (Tuta absoluta)? How to fight?



The tomato-friendly, scientific name Tuta absoluta was first seen in South America in 1965. In 2006, he entered Europe from Spain. Thanks to the quarantine measures implemented, the period of spreading to Europe is prolonged. After Europe-wide, its expansion has accelerated. first time in Turkey was detected in 2009. The most important reason for this is that quarantine measures are not implemented among the European Union countries. In addition to not implementing quarantine measures, tomato sauce spreads very quickly in our country as it has a very fast breeding and spreading structure. This harmful damage that spreads to many of the tomatoes produced is causing serious damage.


Tomatoes are the most important tomatoes harmful, and besides tomatoes, many plants from the family of Solanaceae have damaged in the same way. tomato moth is a native species of South America, Turkey on the Aegean and the entrance of the Mediterranean have made it here and spread quickly. This harmful factor is a very important threat to our farmers. Tomatoes' confidence is particularly high in the Aegean and Mediterranean regions where they have entered the country, and the populations in the regions are increasing day by day. It has been observed that this spread has increased after 2010, causing too much damage to growing environments. It has been observed that this spread which took place in about 1 year gave 100% damage to tomatoes.

The adult is thin, about 7 mm in length. The grayish brown wings have black spots. The antennas resemble thread. Male individuals live 6-7 days and their teeth live 10-15 days. A female moth leaves 120-260 eggs during her life. These eggs are not only transferred to tomatoes, but to all sides of the plant. Egg is 0.4 mm long. It has a cylindrical structure. Cream-yellow color shows itself. The ovaries open in 4-5 days. The larva from the egg is creamy and the head is black. It looks like a crawler. This harmful 4 larval period passes. The height of 0.9 mm in the first period and 8 mm in the fourth period. Larva live 13-15 days. From day 10 onwards, the color starts to shine. The pupa is 6 mm tall and the color is light brown. It can give 12 generations a year. It is known that the places where the Mediterranean climate is seen are growing more rapidly.

It enters the larvae of tomato juice by piercing through the leaf, the body and the fruit. It opens wide transparent gaps in the foliage. Then these voids turn into brown. The pores of the pest grow into irregularities and increase towards the stem of the fruit. Reliable black colored nutrient residues are visible in the open space of the pond and the fruit. Especially the black residues on the leaves are striking. These holes in the grove then cause decay and damage. Decayed and damaged fruits are not suitable for consumption and sale, which causes your labor to be wasted. Tomato can be mixed with other harmful substances. Tomatoes are more likely to be found in unripe tomatoes, and the holes in the fruit are smaller in diameter than other pests. Tomato Juice, unprepared, 50-100% of untreated plants will cause harvest loss and farming will cause economic damages. As long as no measures are taken, it causes the manufacturer's labor to disappear. For this reason, it must be taken in advance and struggled in this regard. 'How to fight tomatoes with the urge?' There are many methods developed to answer the question.

Cultural precautions that can be taken in battle with tomatoes


All periods of tomato juice can be transported with seedlings, plant juice, tomato juice, as well as safe, box and transportation vehicles. For this reason, care should be taken not to contaminate these materials with harmful substances, quarantine measures should be taken during the passage of the products to the area or zone. If it is not careful, it will also cause harm to other plants and cause great damage.

One of the main reasons for the spread of tomato sauce is the use of fidelites which are harmful during production. Care should be taken not to cause any harm to fidelites when they are used. In the same way, harmful plants must be removed from the production area. It is very important that the weed, which is a reliable host, is not kept in the production area and its vicinity.

Soil release and solarization are among the cultural precautions that can be taken in combat with the destruction of harmful and harvested land after harvest, the cultivation of non-host products, the covering of open areas with tulle, irrigation and fertilization in accordance with cultivation technique.

Pheromone trap for tomato-friendly (tuta)


Pheromone trap is used by the manufacturer as biotechnical method. These traps are mostly used for the detection of the existence of tomato sauce, collective catching and observation purposes. The more harmful they are caught, the more they will breed and multiply. Traps set aside from the seedling period are counted twice a week and recorded. These pheromones used for tomato-based challenge attract only male individuals. The effect of a pheromone capsule lasts 6 weeks. Chemical and biotechnical struggle is started according to the number of moths trapped in traps. The harmful effects of the pollutant and the plant are sent to the institute for diagnosis.

Water trap


A few drops of detergent are placed inside the 40-60 cm water filled basins. Put pheromone capsules on the edges. The harmful substances from the pheromone drown in the water and sink into the water due to the dishwashing detergent in the water.

Delta trap


Roof-shaped delta traps are established. Place the adhesive plate on the base and place it on the pheromone capsule. The impurities coming from the pheromone stick to the adhesive sheet.

Pheromone trap locations and prices


The pheromone traps, which are highly effective capture and observation methods, are easily accessible from the internet. 'How much do pheromone trap?', 'Where can I buy pheromone trap?' they can browse the following internet sites.

Mechanical struggle with tomatoes


It is a method applied by removing damaged, damaged leaves. This practice has been exemplified in the study named 'Tomato-relief, Tuta absoluta (Lepidoptera: Gelechiidae)' in the struggle of removing harmful and detached leaves from the environment and researching the effect of azadirachtin application altogether. Plants in 5 rows in 10 m area were checked. If the remains of the plants are left on the leaves of the plants, they are left untouched. However, the leaves have been removed from the production area before the larval reaches the stage. Larvae covered leaves were observed, the length of the holes formed by the larvae, the period of the larvae were examined. The leaves were left for the next census when they were found to be at the beginning of Larva's developmental period.

This is to observe the production contributions of the intact parts of the leaves from which the destructive damage begins to damage. This process continued until the harvesting period. When the tomato fruit was first damaged, the first fruits that had been damaged were removed from the environment. NeemAzal-T / S was then applied to the immature fruit only with a sprayer at a dose of 50 ml / 10 l water 3 times at intervals of 15 days.
As a result of this study, it was observed that the harm of tomato guile (tuta) was significantly reduced when mechanical combat and partial spraying were applied together. As a result, mechanical struggle and partial disinfection have proved to be an important effect in combat with tomatoes' reliance.

Biological struggle with tomatoes


More natural methods should be preferred before the chemical in the battle with the vitality of tomatoes. The methods applied to get rid of pests can also damage the product. In order to minimize this loss, biological fighting methods should be tried first. If chemical struggle is needed, it is necessary to use finished protective drugs which will cause minimal damage to natural enemies. Care must be taken to protect the benefits at this point.

Tomato entered the safe Mediterranean countries towards the end of 2006. However, many natural enemies of this harmful have been identified. Trichogramma pretiosum Riley and Podisus nigrispinus Nesidocorus tenuis, Macrlophus caliginosus are the most effective beneficiaries in the battle with the vitality of tomatoes. It is also among the natural enemies of the tomato sauce. From these natural enemies, Trichogramma spp. (Hym .: Trichogrammatidae) parasitizes the eggs of the pest, and is effective in the larval stage of the pests of Braconidae, Eulophidae and Chalcididae. Nesidiocorus tenuis and Macrolophus caliginosus (Hem .: Miridae) are fed on eggs and larvae of the pest.

Larval will spend most of his time in the gallery. However, in the second period, larvae can get out of the gallery due to reasons such as temperature and food consumption. This situation is very important in terms of biological fighting. When the larvae go out of the gallery, they will be easier to parasite or hunt by natural enemies.

Chemical struggle with tomatoes


Chemical fighting is not always the first choice. If tomatoes can not be tackled with natural methods with the help of chemical countermeasures techniques are applied. At this point, time of spraying, spraying technique, plant protection products and doses to be used, tools and machines to be used are very important. For the detection of the presence of tomato sauce and for the purpose of observation, the pheromone traps are used in the field and in the sera from the beginning of production. The number of these is determined as 1-2 traps per week in the field and 1 trap in the sera. When the first pest is detected in the trap, at least 100 plants in the production area are controlled. This number may vary depending on the size of the production area. The plant is checked for flowers, leaves, stalks, fruit and occasion days, eggs and larvae.

Technique is very important in medicine. The medicine needs to reach all over the plant. The drug should reach the lower surface of the lid in particular. The application should be done so that all sides of the plant are covered. Drug time is also important at this point. The plants should be checked about 1 week after spraying. If necessary, it should be sprayed again.

During the selection of the crop protection products to be used, there are points to be considered in terms of protecting the fruits from harm. At this stage ministerial licensed medicines should be used. When these drugs are used, attention should also be paid to their dosage. These drugs and their active ingredients with their doses can be listed as follows: 45 g / l Chlorantraniliprole + 18 g / l Abamectin (Greenhouse) - 80 ml / 100 liters water, Spinosad 480 g / l (Greenhouse) - 25 ml / 100 liters water, Metaflumizone 240 g / l (Field-Greenhouse) - 100 ml / da, Azadirachtin 10 g / l (Greenhouse) - 300 ml / 100 l water (2 medications with 7 days interval)

When these drugs are used, the time interval between the last application and harvest is determined as 3 days. Plant protection medicines can be supplied easily from the internet.
