Insecticidas naturales contra la mosca blanca en tomate. El poder de Nakar.

Natural insecticides against whiteflies on Tomato Plants

Whitefly pests are causing serious problems in the Spanish tomato crops, especially due to the transmission of viruses such as Tomato Yellow Leaf Curl Virus (TYLCV). Hence the importance of combating this problem through an integrated management that includes effective natural insecticides against whitefly on tomato plants.

In order to keep the whitefly population at bay, integrated pest management is the best method of action. Its objective is the rational and efficient control of pests and diseases, minimizing the amount of residues in the products to be harvested. It is necessary combine cultural measures, biological control and phytosanitary treatments, with priority of natural ones versus chemicals.

Farmers do not find it easy to find specialized, effective natural formulations that do not leave residues in the crop, but they exist.

The best natural insecticides against whiteflies on tomato plants

Natural insecticides against whiteflies on Tomato Plants

Among all the natural insecticides against whiteflies on tomato plants, Nakar product stands out given the good results it has demonstrated in trials and in commercial application, and given its high specialization. It is a bioinsecticide that presents excellent contact control of soft shell insects in all stages of development and especially of the whitefly in tomato.

Its state-of-the-art formulation gives it the ability to penetrate and fragment the lipoprotein matrix of insect cell membranes. The disruption of the membrane causes the evacuation of the cellular contents causing the dehydration and death of the insects.

Given its natural origin and its compatibility with the action of the natural predators and parasitoids of the whitefly is an ideal tool for Integrated Pest Management (IPM), so that the insecticide’s power is combined with the biological control action.

Along the same lines, Pirecris, an insecticide based on natural pyrethrins, is made with co-formulants of botanical origin, totally natural, so it does not use Piperonil Peroxide (PBO) as synergist. Its formula is patented.

Advantages of the natural insecticides against the whiteflies on tomato plants

1.- No security deadlines

These natural insecticides do not have safety period. In fact, both Pirecris and Nakar can be applied even the day before harvesting.

 2.- Resistance management

Optimum result in resistance management strategies.

3.- Efficacy in all biological stages of insects

Although their efficacy develops over all biological stages of insects, the insects are more vulnerable to the effects of the active substance in its immature stages of development and non-flying phases.

 4.- Wetting effect

The fact that whitefly populations are placed on the underside of the leaves conditions the effectiveness of the products that act by contact, so it is advisable to use wetters.

However, Nakar has achieved a potentiating and wetting effect, so that it improves adhesion in spray applications. Moreover, it increases the adhesion of other treatments because it decreases the surface tension of the water and increases the contact surface, as well as the contact time between the pathogen and the applied active material.

 5.- Avoid molasses and bold in the crops

The whitefly secretes a species of molasses that hinders the growth of the plant because it interferes with photosynthesis and causes less vigor and, therefore, a worse quality in the fruits. This molasses favors the attack of the fungus that causes the bold in leaves, flowers and fruits, and also reduces the photosynthetic capacity of the vegetable and its respiration, depreciating the quality of the harvest, but also hindering the penetration of phytosanitary treatments.

Besides its potential as a natural insecticide, Nakar contributes to the cleaning of these molasses produced by attacks of sucking insects such as the whiteflies, in a way that avoids the fatal spread of fungi. In the same way, Nakar cleans the bold formed by the fungi.

6.- Efficiency comparable to chemicals

The different tests carried out with the bio-insecticide Nakar (SEIPASA) have shown that the efficacy of this natural insecticide equals the reference chemical in whitefly control, with the added value of not leaving residues and being suitable for integrated and ecological production.

In the last study carried out by researchers at the Technological Park of Almería (Tecnova) on integrated control of whitefly on greenhouse tomato, results confirmed the high efficiency of Nakar on immature and adult populations of this pest, cutting off their biological reproduction.

The synergy of this product with the action of Pirecris was conclusive in the control of the whitefly Bemisia tabaci.

Sandía virus venas amarillas

Cucumber vein yellowing virus CVYV

This disease, transmitted by the white fly, Bemisia Tabaci, affects cucurbitaceae such as the cucumber, courgette, melon or watermelon

The disease known as “Cucumber vein yellowing virus” (CVYV) is transmitted through the adult individuals of the whitefly (Bemisia tabaci) and affects cucurbitaceae species such as the cucumber, courgette, melon or water melon.

It was located for the first time in 1960 in cucurbitaceae cultivated in Israel. It appears to be related to the sweet potato mild mottle virus (SPMMV). It is wide-spread in Western Mediterranean countries, and since 2001 it affects the fields of Andalusia.

Symptoms of the vein yellowing virus

In cucumber and melos:
Yellowing of the veins is observed in the leaves of the shoot, a characteristic whence the virus derives its name, although, depending on the moment of infection, this yellowing can also occur in a generalised manner in the entire plant.  The plant development is also less.

In cucumber fruit, a light green, dark green, mosaic occurs, whilst no symptoms occur in melon fruit.

Virus venas amarillas en sandíaIt seems that this virus, associated with the cucurbit yellow stunting disorder  virus (CYSDV), produces a synergism that boosts the symptoms of both virus

In courgette:
The symptoms observed on the leaves are a slight yellowing of the veins.

In watermelon: In leaves where it has been detected, the chlorosis symptoms are very mild and may go unnoticed. At times, they are even symptom-free. A strong internal necrosis has been observed in the fruit, as well as splitting of this fruit, which is attributed to the virus, although whether this is a unique and/or direct consequence has not been entirely demonstrated.

Transmission of the vein yellowing disease

The virus is transmitted by the vector insect, Bemisia Tabaci (Homoptera: Aleyrodidae). The adults of this whitefly can be observed on the backs of the leaves like small insects that measure somewhat more than 1 millimetre long with a yellowish body and white wings due to the secretion of waxes that covers them.

A virus acquisition period of at least 30 minutes is needed, and at least 15 minutes feeding on the plant is required to inoculate it. The insect retains the virus for 6 hours and has a latent period of 75 minutes. Low transmission effectiveness by the Bemisia Tabaci has been indicated, and at least 15 to 20 insects are required per plant for its transmission.

Methods to combat Bemisia Tabaci

The management methods are based mainly on controlling the Bemisia Tabaci vector by means of prevention and culture practices (use of meshes, elimination of plant waste, use of resistant varieties, use of certified virus-free material, …), as well as plant health and integrated management practices.

The Regional Ministry of Agriculture and Fishery of the Junta of Andalusia, advises a series of specific measures:

  • Placement of double mesh on the edges and ridges of the greenhouses and placement of double door or mesh at the entrance.
  • When the climate conditions (especially humidity) permit adequate ventilation of the greenhouse, placement of anti-trip meshes.
  • Use of yellow chromotropic traps.
  • Surveillance and control of the white fly in early cultivation stages and seed beds.
  • Set up the measures relating to cleaning plant remains and weeds in the greenhouse and surrounding areas. Pull out and immediately eliminate plants affected by the virus during cultivation.
  • Not abandoning the crops and carrying out treatment against Bemisia Tabaci before pulling them out is compulsory as a management method, as well as correctly eliminating the plant remains.
  • Leave a rest period of at least one month between one cucurbitaceae crop and the next one to break the cycle of whitefly.

To control the whitefly in the framework of the integrated management of pests, natural specialised plant health products that have proved to be very effective in eradicating Bemisia Tabaci can be resorted to, as is the case of Pirecris.
