Melo, strategy to defend it

Italy has always been a leading country in Europe production of quality apples. Stone fruit defense techniques have undergone significant changes in recent years related to larger ones attention to the environment and the consumer on the one hand, and on the other hand, to the arrival or renewal of new problems that complicated rational and effective defense. To meet the needs of fruit growers BIOGARD®a division of CBC Europe Srl, provides fruit growers with a large number of solutions that are integrated into strategies aimed at sustainability environment and efficiency, according to the criteria of low impact, absence of residues and are not dangerous for the operator.

Use pheromones for the application sexual confusion and use microbiological agrochemicals based on CpGV granulosa virus (Cydia pomonella Granulo Virus) today represent the basic basis for finding an effective and rational strategy defended by a curler (Cydia pomonella).

Systems for sexual confusion on pome fruit can be divided into two groups. On the one hand, a classic passive release regulators which contain a pheromone that then emerges from the walls and is dispersed into the environment and the other side innovative aerosol formulations with active release and timed with various emission programs.

It should always be emphasized that for sexual confusion to be successful it is essential that it be applied before the flight of the species it is directed against begins. In addition, the system must always be foreseen tracking to be able to intervene with emergency treatment if necessary.

BIOGARD® proposes a wide range of means for the application of sexual confusion in various conditions found in the field to defend against the curler:

  • Isomate C plus for the control of leafhoppers (Cydia pomonella) with a single capillary diffuser that can be used even on small areas (1-2 ha);
  • Isomate C TT for control of weevils with a double capillary diffuser for areas larger than two hectares;
  • Isomate C LR MAX TT for the simultaneous destruction of curlers and embroiderers;
  • Isomate C/OFM for the simultaneous control of the weevil and the peach squid (Grapholita molesta) using a single capillary diffuser;
  • Mr. C for exterminating the curler, which consists of an aerosol container in combination with Mr. PROnew timed emitter, pre-programmed and automatically activated when the can is inserted;
  • Mr. C LR aerosol container for simultaneous eradication of curlers and embroiderers;
  • Mr. CG aerosol container for the simultaneous control of curlworm and peach tree.

BIOGARD defense line® then provides an opportunity to intervene with insecticide treatment foliar (larvicides) based on granulovirus (CpGV):

  • Madex Top (CpGV – isolate V15) only for the control of the weevil;
  • Madex Twin (CpGV – isolate V22) for the combined control of the wilt and peach chard and is particularly suitable for interventions just before harvest.

CpGV-based preparations used against the curler find the optimal application period in first generationwhen the larvae, before penetrating the fruits, have a wandering phase during which they can more easily ingest the capsid containing the virion.

It is one of the most feared pestsgray aphid (Dysaphis plantaginea). The danger of this aphid is particularly evident during the flowering period and in the early flowering stages, when the sucking bite causes deformation of the fruits in the fruit set.

BIOGARD®to defend against this dangerous phytophage, he suggests NeemAzal®– T/S. It is an insecticide of botanical origin based on azadirachtin Aextracted from the Neem tree (Azadirachta indica).

Active by contact and ingestion (has a systemic effect), acts primarily as a growth regulator, causes blocking of insect molting (blocks the production of ecdysone, i.e. the molting hormone in the insect class), which results in the death of the insect. It doesn’t have a knockdown action, but it does repellent action (treated leaves are less palatable, less colonized and visited) and prevents oviposition and reduces fitness and fertility of individuals.

The intervention strategy on apple trees includes 2 treatments with NeemAzal®-T/S at a dose of 2-3 l/hectare before and after flowering to control populations of this dangerous aphid in the bud. A mixture with a product such as Plantswith an acidifying function, improves the effectiveness of the treatment.

In recent years, the presencewoolly aphid (Eriosoma lanigerum) in apple orchards both in integrated production and in organic farming. Significant occurrences of phytophages are reported with increasing frequency in major apple production areas.

For this dangerous phytophagous BIOGARD® suggests Naturalis® an insecticide/acaricide containing an entomopathogenic fungus Beauveria bassiana strain ATCC 74040.

Naturalis® It works primarily through contact with spores that, once they reach the target, germinate and attack the host, which dies from nutrient depletion and dehydration.

The treatment should be started at the end of winter, when the first colonies appear, and then continue at a regular interval (3-5 interventions), taking care to moisten the growth well.

Naturalis applications must be set up with some rules in mind:

  • Naturalis works by contact and is therefore essential take good care of watering the plantin the case of aphids, including the stem;
  • Naturalis has no clotting power, repeat the treatment at least 2-3 timesespecially when used alone and not in strategy with other insecticides/acaricides or beneficial insects/mites;
  • be the active ingredient and mushroompay attention to possible fungicide interventions (see the compatibility table, available on the website www.BIOGARD.it).

The Naturalis employment strategy against the wavy aphid counts on execution 3-5 treatments in spring-summer (end of May-June) and further interventions in late summer-autumn, if the aphid resumes its activity and attacks the shoots again. In this way, the presence of the woolly aphid is limited in the moments of resumption of its activity and allows parasitoid Aphelinus bad express its potential for pest control.

Naturalis can be effectively added Soft soapoil of vegetable origin and perfectly compatible with Naturalis, which improves plant resistance to biotic and abiotic stresses and reduces the possibility of secondary problems such as soot.

For fungal diseases BIOGARD® primarily suggests Heliocuivre Terpene-based fungicide containing copper hydroxide for protective treatment against they fallWhile Heliosoufre S Terpene-based antoid with sulfur is indicated for defense against infections they fall in the central stages of the vine’s vegetative cycle.

It is about terpene-based fungicidesor with the addition of terpene alcohols to improve product adherence and persistence while reducing phytotoxicity risks.

It is then possible to use it in a specific antioid function Vitikappa plant protection product based on potassium bicarbonate (KHCO3; concentration 99% w/w), which exerts a complex activity against fungi causing cracking and drying of hyphae up to the total collapse of the mycelium of sensitive fungi. Vitikappa it also affects the vitality of fungal spores.

It is a contact fungicideformulated in a soluble powder, with preventive and curative effects and is particularly suitable for use in a mixture and/or rotation with other pesticides in order to implement strategies against the emergence of resistance and exploit synergies between different mechanisms of action.

Excellent results have also been achieved with the mixture of Vitikappa and Heliosoufre S, as the bicarbonate utilizes the adhesion of the terpenes.

It is a portfolio of innovative, alternative and effective means of application and sustainable defense of the apple tree.

BIOGARD® offers agricultural companies a completely unique proposition that can provide access to the highest level of development in the approach to sustainable reduction of adverse crop conditions.

products allowed in organic farming but which also fit perfectly into rational integrated defense strategies.
