Increases phytoalexin production and improves overall plant health. An ideal adjunct for microbe multiplication in the soil, on the leaf or during microbe brewing.
A spreader / sticker/synergist to improve foliar fertiliser response. Increases target penetration - the natural oils bond with the leaf surface, magnifying the penetration of the spray.
Excellent all-rounder for broad-spectrum nutrition and plant growth promotion. It is a completely natural product and can be used frequently as it is not overloaded with N.P.K.

Can be used as a natural wetter-sticker for use with foliar fertilisers. Effective over a wide pH range and is a recognised bio-balancer.
A broad-spectrum sanitation and water treatment solution. Effective over a wide pH area against a range of fungi and bacterial pathogens.
Promotes more efficient photosynthesis, increasing sugar and mineral levels (brix) in all plants, particularly orchard and vine crops. Produces an armour-like protective layer in the outer cell wall which can aid in the recovery of previously affected pathogen-damaged plants.
A combination of minerals to govern cell strength and cell division.
Helps to produce healthy plants that become more resistant to attack from insect pests or disease and this can result in a reduced need for application of plant protection materials.
Improves the nutritional value of grazing pasture with better balance between protein fibre and energy. Grazing animals need the energy to adequately convert and use the protein.
Provides an 'organic' where plants are grown in either soil or a 'non-soil' medium resulting in better quality, better tasting fruit and vegetables with a longer shelf life.
E-Protect is a brewed inoculum consisting of three ingredients. When these are combined, it gives a blend of bacterial strains and beneficial fungi.
Features a unique capacity to dissolve minerals and trace elements. This feature has tremendous importance for fast-tracking the plant availability of rock minerals, rock phosphate and lime.
It is a highly effective soil conditioner and powerful fungi promotant. It exhibits all of the characteristics of soluble humic acid, with virtually none of the myriad of compatibility problems.
This is a powerful phosphate-based liquid fertiliser with excellent brix-building capacity. Improves photosynthesis and earlier root development.
Is a humic acid liquid for use as a fertiliser, stabiliser/magnifier. plant growth promotant, soil life activator and soil conditiioner.
Downy mildew (DM) is an oomycetes (water mould) closely related to Pythium and phytophthora and also the moulds that appear in damp showers.
Each plant species tends to have its own spp. of DM and rose DM is called sparsa because the fungal spores are relatively sparse.
The spores are airborne and are activated when weather conditions are right i.e. cold nights and high RH.
DM can survive for a long time in rose stems as fungal strands so even healthy looking plants can contain the problem just waiting for the weather to change which explains how good looking crops can turn so quickly.
The first sign of trouble on the leaves and stems is a purplish/brown spot which can be confused with nutrient problems. Also the rose DM sometimes does not produce the mat of spores on the back of the leaves hence the name sparsa. Once DM has taken hold it can’t be stopped at that point and it is advisable to remove the damaged stems after you have applied treatment so that any surviving spores are taken from the house. Good management techniques are needed in this job to avoid spreading the spores.
In wet weather with high humidity DM can explode overnight if the spores have had 6 hours of the right conditions. Fog or mist is perfect for infection which is why the problem is often worse under polythene.
In the morning sporangia have formed on the leaves which are spread to new plants by air movement. The best temperature for the DM is around 14C with a RH of 85%.
Above or below this temp tends to hold DM in a static position but does not kill it.DM can also survive as oospores in dead material on the floor and in the top of the pot so good hygiene is essential as with many other problems.
A good drench with E-CleanTM will help keep the spores down although once the DM has taken hold this will need to done very regularly. The E-CleanTM will have no effect on the DM within the plant.
Some growers see a proliferation of mildews and other problems when there is a background weed problem so it makes sense to keep the area as clean as possible. Also poor light from dirty glass/polythene or old polythene can antagonise the situation so the brighter the light the less of a problem you will have. This can also have an effect on un-protected crops where rubbish or unkept windbreaks cause excessive shade.
There is no doubt that healthy plants get fewer problems but this doesn’t mean we can ignore the possibility of infection as even low nutrient levels that are not apparent can lead to problems. This goes back to the argument for raising the brix of the plants which is difficult at any time but especially so in short light periods.
Use a wide range of techniques to prevent DM including environmental, organic and chemical.
The starting point is to make sure you have the correct feeding regime so that the plants are in good condition without excessive N in the leaves and the other nutrients in balance. In times of poor weather I find it well worth dropping the Nitrogen levels as against the other nutrients plus cutting out a lot of fertigation in favour of foliar feeding which can be a lot more suitable. Foliar feeding can be many times more effective than fertigation.
At certain times of the year and at certain stages of growth foliar feeding builds the strength of the plant without softening growth, which is more susceptible to attack. On many crops a Urea spray chelated with a little Fulvic acid is a far better option than putting in Nitrates through the roots, an idea I will go into further in an article called foliar feeding.
Over the years I have found that a good background rate of Trichoderma (Elite-HKLTM) and Bacillus subtilus (Elite-GoldTM) can alter the starting point of DM [and] have actually cured the disease with a heavy drench after it has broken out, so it is safe to assume, that if these products are kept in the root zone, where they belong they will be able to either prevent infection or drastically reduce the harmful effects.
In the UK Bacillus subtilus are one of the major products used against DM in many crops. I tend to keep a colony going by the regular application of a brewed inoculum (E-ProtectTM) which gives a whole range of microbes and fungal spores around the root zone.
Constant spraying with E-CleanTM will also help reduce all harmful pathogen spores and two spotted mite eggs.
It is important in none biological programmes not to use too much E-CleanTM on the foliage, as it will deter the good pathogens as well as the bad.
As far as the ground is concerned it is important to use E-CleanTM lightly so that it does not build up in the soil where it will again be detrimental to natural flora and fauna and to help with this I drench with E-ProtectTM to keep the numbers of microbes well up. Remember that after an attack every effected stem that is left on holds the possibility of re-infection the next time conditions are right.
Also remember that secateurs used for cutting will transmit disease if they are not dipped very regularly (at least after each row and after each plant where a problem exists or if cuttings are being taken); E-CleanTM is ideal for this.
Keep the nutrition of the plants up to the maximum as an actively growing plant will automatically fight off pest and disease on its own, provided the right balance is maintained.
In the UK and Europe Bacillus subtilis has long been used on many crops as part of the DM control programme. Indeed on seedlings it became almost the sole product used as very little chemical is now used on seedlings at all. With this in mind it may be worth using Elite-GoldTM mixed with Kelp 372TM and Fulvic acid (Carrier1400TM) plus a source of Nitrogen – preferably urea or biological as in (Aero-LiberateTM) as a simple type of compost tea to build the Bacillus numbers in the root zone. If this is tried it must be pointed out that it would have to be applied regularly (at least every 10-14 days) and over a long period of time to build up positive effects.
