PREPARATION AND TESTING OF THE ANTI FUNGAL, ANTI TANNED PRODUCTS ON THE GRAPEFRUIT TREE, ON THE BASIS OF APPLICATION OF NANO COMPOUNDS

Abstract

Grapefruit and citrus fruits often fungal infection in leaves and fruits, such as scabies, anthracnose, rust,
melasma, tan. Fungal diseases make greatly influence in the productivity, quality and colors of grapefruit,
especially is Dien grapefruit. Organic fungicides currently are restricted use due to have high toxicity and pollute
the environment. Nano-products with high anti fungal effect, non-toxic and non-polluting environment are
being interested. This paper presents the results of research on preparation and testing of anti fungal for Dien
grapefruit from nano compounds. The preparations is dispensed with the ratio of substances: 500 mg/liter of
nano silver, 10,000mg/liter of nano copper oxichloride, 50g/liter of polyvinylpyrrolidone, 15g/liter of nonyl
phenol ethoxylate and 15g/liter of trietanolamine. Validity of anti Rust fungi, anti Anthracnose fungi and anti
Scabies of the product reaches 71.5%, anti tanned grapefruit reaches 80.6% at the concentration is 100ml/10
liters of water. At the concentration of 150ml/10 liters of water, the validity of anti fungal reaches 79.3%, anti
tanned reaches 85.1%. And at the concentration of 200ml/10 liters of water, the preparations for validity of anti
fungal reaches 83.7%, anti tanned reaches 90.3%.
