Nanoparticles of Sulfur as Fungicidal Products for Agriculture

Abstract

Sulfur is a nonmetallic element necessary for life. Sulfur nanopartieles display unique physical and chemical feature because of effects such as the quantum size effect, mini size effect, surface effect and macro-quantum tunnel effect. So sulfur nanoparticles would present higher efficacies such as removal of heavy metals, radical-scavenging, antimicrobial activity, antioxidant and antitumor activities. It is used as a fungicide product in agriculture, also used in medicine, to obtain sulfur fertilizers and cosmetics industries, as well as in obtaining nanocomposite lithium batteries. In synthesis of sulfur nanowires with carbon to from hybrid materials with useful properties for gas sensor and catalytic applications. This work presents the results of obtaining the sulfur nanoparticles, which can be used in agriculture as a fungicide treatment. Sulfur nanoparticles were obtained by modifying the surface of sulfur by various surfactants including cetyltriammoniumbromide (CTABr), Sulfanol, Sodium Ligninsulfonate (CMN), Sodium salt of polynaphthalene sulphonic acid (NNO), water soluble polymer sodium carboxymethylcellulose (NaCMC), mineral mixtures and their compositions. The size and the structure of sulfur nanoparticles were determined by methods as LSA, XRD, SEM. Been studied the value of adsorption at the interface of solid/gas. It is shown that the nanoparticles have a sulfur monoclinic B-form, and their average size is in the range 500-1000 nm. The received products can be considered as perspective forms of application in agriculture.

Structuring of an Aqueous Suspension of a Sulfur-Gypsum Mixture in the Presence of a Composition of Surfactants and Water-Soluble Polymers

“…Осыған байланысты күкіртті халық шаруашылығында тиімді пайдалануды зерттеу өзекті мәселелердің бірі болып табылады. Бұл затты әдетте медицинада, ауыл шаруашылығында, ветеринарияда, химиялық тыңайтқыш және нанокомпозитті литий батерияларын алуда пайдаланады [7][8][9][10]. Көптеген жұмыстарда мұнай өндірісіндегі жинақталған күкіртті тұрмыста бос жертөлелердегі, көкөніс, астық қоймаларындағы, шөп сақтайтын орындардағы, шарап қоймаларындағы, тоңазытқыш камералар мен жылыжайлардағы ауру қоздырғыштарды, бактериалды инфекцияларды, зең саңырауқұлақтарын, жәндіктерді жоюдағы тиімді құрал ретінде отандық өнім ретінде түтіндеуші күкіртті (күкірт шашкалары) өндіру жолы ұсынылды.…”

A Review on Wide Range Application of Nanoparticles in Agriculture and its Implications in Plant Disease Management

“…In the conventional application methods like spraying and broadcasting which cause losses by leaching, runoff, evaporation, microbial and photolytic degradation. In these conventional methods, fewer amounts of fertilizers get available to the plants wherein about 40-70% Nitrogen, 80-90% Phosphorus and 50-90% potassium get lost in the environment [38]. Due to this loss of fertilizers farmers apply more fertilizers which cause pollution, reduction of microflora and have residual effect on plant produce.…”

Synthesis and application of sulfur nanoparticles

“…In order to improve the SNP production by mechanical milling, a surfactant assisted route has been developed: colloid milling (Turganbay et al, 2012). In this method cetyltrimethylammonium bromide (CTAB), sulfanol, sodium lignin sulfonate, sodium salt of polynaphthalene sulfonic acid or water soluble polymer sodium carboxymethylcellulose (NaCMC) are added as surface active agents to reduce the surface tension at the solid/liquid interface and thus facilitate the formation of a stable suspension of sulfur.…”
