Perfect  Bl end fertilizers with Phytophthora fighting increased concentrations of mycorrhizal fungus spores are designed to provide maximum Phytophthora fighting concentrations of mycorrhizae colonies.

High mycorrhizae formulations are now available for use in fighting Phytophthora diseased root systems. Scientifically formulated Perfect
Blend with mycorrhizae provides a two way-program for defeating Phytophthora attack. Phytophthora frequently attacks plants, trees, and turf that have poor nutrition or have suffered under repeated applications of synthetic fertilizers which weaken or destroy the soil micro-organisms that normally protect trees from root rot diseases. Perfect Blend mycorrhizae inoculated fertilizers provide the complete nutrition that enables the formation of complex fulvic and humic acids that arethe most efficient foods for soil micro-organisms. Fortified with these nutrients, and inoculated with beneficial mycorrhizae spores, a plant can quickly rebuild a Phytophthora defense system that has been weakened or destroyed by previous synthetic fertilizer applications. Over phosphorus application will destroy the beneficial mycorrhizal
colonies that actually protect tree roots by at least two important mechanisms. These mechanisms include the physical shielding of the tree roots by the beneficial mycorrhizal fungus and also the production of antibiotics that can kill the attacking Phytophthora fungus.

Can other fertilizers protect your trees from Phytophthora? Don't bet on it. Only Perfect Blend has a high technology formulation that
provides the slow release transfer of nutrients that are critical to the health and growth of the beneficial mycorrhizal contained within the
formulation. Perfect Blend with mycorrhizal should be injected or poured into the root zone or worked into the soil for to provide long term protection. The secret of the Perfect Blend formulations is that not only does Perfect Blend include mycorrhizae spores it is formulated to provide growing and expanding mycorrhizal colonies with the food necessary for the fungus to become established and spread. Simply [jutting mycorrhizae into the soil alone is not as effective as putting mycorrhizae into the soil along with a long term slow release organic food source. We invite you to try the new high mycorrhizae formulations. Ask your distributor for either the 100% organic 4-4-4 or 7-2-2 with enhanced Phytophthora grade mycorrhizae next time you aerate your soils. After aeration apply at the rate of approximately 1 ton per acre for maximum Phytophthora fighting   effectiveness. Its called  an  Phyto-Fighter - ask for it.

At Perfect Blend we believe you can evaluate science abstracts just as well as we can. Here are the cites for your review. Want more? Just ask. We have dozens.

Bio-control of Phytophthora root pathogens by AMF: a study of possible mechanisms
NORMAN, JAMES1, CLARA VIG01, JILL POVEY1, NEIL GOW2 , MIKE MORRIS2, KYRSTEN BLACK! &JOHN HOOKER!. 1 Soil Biology Unit, Land Resources Department, SAC Craibstone Estate, Aberdeen AB22 9TQ, UK. 2Department of Molecular and Cell Biology, University of
Aberdeen.Marischal College, Aberdeen AB9 IAS, UK. There are many reports in the literature of interactions between arbuscular mycorrhizal fungi (AMF) and Phytophthora root pathogens. Effective management of the symbiont-pathogen interaction requires an understanding of the mechanisms involved in order to ensure a consistent response. Interactions between Lycopersicon esculentum,
Fragariae x ananassa Duchesne and Phytophthora were investigated andupto60%diseasecontrol wasmeasured in rootsof AMF colonised
plants. Further studies aimed to identify the mechanisms involved and measured the impact of AMF on root architecture,  porangiaformation, zoospore taxis and root tip electrical fields.

1994    Contribution    of   arbuscular    mycorrhizal    to    biological protection of micro pro pa gated pineapple nananas-comosus (L) Merr against phytophthora cinnamomi rands, agricultural science in Finland 3:241-251 ENCE IN  FINLAND3:241-251.


Phytophthora cinnamomi Rands causes root rot of pineapple (Ananas comosus (L) Men.) and the development of this disease is harmftfl for fruit production. Micropropagated plants of two varieties, Queen Tahiti and Smooth Cayenne (clone CYO), were inoculated at transplanting from axenic conditions with an arbuscular mycorhizal  thngus to evaluate the importance ofendomycorrhiza development for biological protection against R cinnamomi. Growth and mineral nutrition of endomycorrhizal plants were not affected by different inoculum levels of P. cinnamomi, whilst they were reduced for nonmycorrhizal plants. Root/shoot ratio of endomycorrhizal plants was lower than that of non-mycorrhizal plants, and the pathogen did not modify this effect except at highest inoculum levels of P. cinnamomi. Endomycorrhizal colonization was not altered by the pathogen; however symbiotic functioning was reduced by the highest concentration of inoculum of P. cinnamomi. Endomycorrhization is an interesting biotechnology forth e produ cti on of micropropagated pineappl e.
