Heptaldehyde and its derivatives has got application in fungicide and insecticide formulations. It is very effective against all four wood decay fungi. It can be used in combination with undecylenic acid and oenanthol bisulfite. It protects the crop from fungal diseases in organic way, the cost effective organic solution with longer periods of protection from fungal diseases. The diseases include leaf spots, Downey Mildew, Powdery Mildew, Blights, and Sheath Rots etc. It has a broad spectrum of antifungal activity for a wide range of plants, vegetables and fruits. The advantages of these compounds are that they are safe and economical.

It can be used in formulations as an insecticide that can be safely used and can be economically prepared in large quantities and kept in storage for an indefinitely long time until there is need for its use. The product is non-poisonous to humanity and does not cause burns when brought into contact with the skin.

The material has volatile constituents therein although its vapor pressure is low so that it does not become rapidly dissipated in the air when it is exposed to attract insects or plant pests.

This material may be used in the usual ways that insecticides are used for destroying insects or pests. It has been found to be particularly useful for getting rid of Japanese and other winged insects since they are strongly attracted by the odor of the material. When the material is placed, for example, in an ordinary type of beetle trap such as an open vessel with baffles above the liquid, the insects are attracted by the odor and when they approach the bait and hover over the liquid, the concentrated vapors seem to paralyze them and they consequently fall into the liquid and perish.

1. Heptaldehyde compounds such as heptaldehyde and heptaldehyde bisulfite are exceptionally effective in inhibiting the growth of, or killing pathogenic fungus infection of the skin and particularly, the fungi of the genus Trichophyton which are responsible for tinea pedis.

2. Heptaldehyde bisulfite is an effective fungicidal and fungistatic agent against the dermatophytes responsible for common rnycotic infection even at lower concentrations.Heptaldehyde is also effective against all the listed dermatophytes at 0.5% concentration.

3. Heptaldehyde sodium bisulfite is nontoxic to humans and lower animals and non-irritating to the skin

4. Heptaldehyde and heptaldehyde bisulfite are effective over a wide range of pH.

5. Heptaldehyde and heptaldehyde bisulfite can be incorporated into the standard types of ointment bases.

6. Heptaldehyde and Heptaldehyde bisulfite may also be used in the form of a dermatologic dusting powder by combining them with a diluent powder consisting substantially of talc, fullers earth or other inert natural diluent powders.

7. Heptaldehyde bisulfite can also be used as a dusting powder in its undiluted state.

8. Heptaldehyde bisulfite can be incorporated into a 70% aqueous ethyl alcoholsolution to the extent of 5%

9. Heptaldehyde bisulfite is non-volatile and therefore, is retained longer on the surfaces where it is applied.
