Why Majestik

Use Majestik to control spider mites and whitefly adults and eggs in outdoor and protected crops.

Majestik acts fast on contact, yet has 0-day harvest interval, with short persistence in the crop.

Based on a naturally-derived food additive (49% w/w maltodextrin), Majestik is suitable for IPM and low-residue programmes, and is accepted for organic use.

It allows you to introduce beneficials quickly and safely – and indeed works in tandem with beneficial wasps that seek out pupae.

IPM compatibility

Key beneficials show how high levels of survival after crop are treated with Majestik 2.5%.

Mode of action

Classed in IRAC group UN, Majestik helps avoid resistance. In fact, none is recorded for this product.

Its effectiveness is simple: the active substance blocks the insect’s spiracles (breathing holes), leading to asphyxiation.

And don’t forget: in case of high pest pressure, you’ll benefit from using Majestik alongside Botanigard.

How maltodextrin works:
 

Mode of Action : Electron Micrograph

Proof

When to apply

Spray at first sign of pest attack; maximum 20 applications per crop.   As with all crop protection products derived from naturally-occurring substances, you’ll need to apply Majestik using best practice to achieve optimum results. Your advisor will confirm what is appropriate.

Why Spruzit

Use Spruzit to control biting and sucking pests – spider mites, aphids and caterpillars – in carrots, brassicas and an extensive range of outdoor and fully-enclosed crops.

It’s highly effective, yet allows you to introduce beneficials quickly and safely soon after application. Short persistence and a 0-day harvest interval contribute to bee safety, the flexibility of the product and lower impact on the environment. Together with a novel IRAC class (Group 3 + UNE) and organic approval, this makes Spruzit a strong contender for resistance management in your IPM programme.

Gives Double Defence

Spruzit delivers two hits against pests – one reason why we call it ‘smarter’.

The first active gives quick knock-down, particularly on caterpillars. Natural pyrethrins in chrysanthemum flowers act on sodium channels in the insect’s nervous system.

At the same time, the natural rapeseed oil base has a physical impact; a mixture of triglycerides derived from fatty acids, it blocks the pest’s trachea.

In addition, as you’ll see below, independent bodies show that Spruzit’s oil content helps reduce pest-transmitted viruses

 

 

How Spruzit works

Pyrethrins:       

  • Disrupt sodium channels

 

Insect nervous system 

 

Rapeseed oil:

  • Increases absorption and penetration
  • Damages spiracles
  • Softens the cuticle

Insect anatomy

Proof

Trials show that Spruzit gives effective broad-spectrum pest control on a wide range of outdoor crops.

When to use

Timing and dose rate with Spruzit depend on target pest and crop height, though in general it's two applications for all crops and four for many. As with all crop protection products derived from naturally-occuring substances, you'll need to apply Spruzit using best practice to achieve optimum results. Please consult your advisor.

Why Botanigard

Use Botanigard mainly against whitefly in fully-enclosed veg crops. You may also see side-effect activity on thrips, as well as spider mites, aphids and some beetle species through its contact action.

It’s ideal for ICM and IPM systems, especially where you need to be compliant with low-residue programmes. There’s no harvest interval: Botanigard  occurs naturally in the soil.

However, Botanigard comes into its own under high whitefly pressure, when you can use it alongside Majestik to create an effective IPM programme across the insect lifecycle.

Using Botanigard with Majestik

Targeted control of the whitefly lifecycle

Mode of action

Put simply, Botanigard is a fungus that produces toxins and feeds on the insect.

In more detail, it’s a microbiological insecticide containing 200 g/kg of the entomopathogenic fungus Beauveria bassiana strain GHA, which is particularly aggressive. Unlike bacterial and viral pathogens of insects, Beauveria infects by contact and does not need to be ingested.

Beauveria bassiana is found naturally in soils and occurs as white muscadine disease in insects. When the fungal spores come in contact with the cuticle of susceptible insects, they germinate and grow directly through the cuticle to the inner body of the host. The fungus proliferates throughout the insect’s body, producing toxins, draining the insect of nutrients and eventually killing it.

Once the fungus has killed its host, it grows back out through the softer portions of the cuticle, covering the insect with a layer of white mould (hence ‘white muscadine’). This may take several days under normal conditions. The mould then produces millions of new infective spores (ascospores) that are released to the environment to find the next host.

Proof

Trials show Botanigard to be highly effective against at least one of the key vectors for virus transmission in veg crops.

Easy tank-mixing

You can tank-mix Botanigard with other active ingredients, but need to choose carefully. For the most up-to-date tank-mix sheet, please contact Certis.

When to apply

Timing and dose vary by crop  , so consult your advisor. Botanigard WP contains living microorganism, so it’s essential to follow best-practice guidelines – in particular, maintaining viability of the spores prior, during and after use – to maximise efficacy on targets such as whitefly and thrips. Again, your advisor will confirm what is appropriate.

Studies show that using a biopesticide containing rapeseed oil, such as Spruzit, can reduce the spread of viruses through aphid vectors and is therefore a significant aid to resistance management.

Why this is important

We all know that insect pests spread damaging, costly viruses in valuable veg crops. In the UK national carrot crop alone, losses are estimated at 15%, worth £20 million in 2015 at farm gate prices. Some emerging threats such as CYLV (carrot yellow leaf virus) can be undetectable during processing, leading to total crop rejection¹.

The peach-potato (or green peach) aphid (Myzus persicae) is a highly efficient virus vector² and can transmit more than 150 types of virus³.

It’s therefore a concern that the peach-potato aphid has multiple resistance mechanisms, while the willow-carrot aphid is becoming resistant to synthetic pyrethroids¹.

How rapeseed oil makes a difference

Some conventional insecticides take time to control pests, allowing viruses to cause damage in vegetable crops. Pyrethrins, one of the active substances in Spruzit, give the necessary fast, thorough knock-down to prevent this. But perhaps more significant is its rapeseed oil base in providing a physical solution - which is why we say it offers ‘Double Defence’.

Field and greenhouse trials comparing rapeseed spray oil with other pesticides against green peach aphid in pepper show high levels of efficacy and persistence, due to the total reduction of newly-deposited white eggs, and that the mode of action suffocates insects and mites, making resistance unlikely².

In addition, modern, non-mineral horticultural oils such as rapeseed oil are less disruptive than conventional insecticides to natural enemies and non-toxic to vertebrates, break down easily in the environment and are generally much safer to use*.
