The objective of the present study is to investigate the impact of spraying boric acid on vegetative and reproductive growth of ‘Camarosa’ strawberry (Fragaria × ananassa Duch.). The strawberry plants were sprayed with Boric acid at 0 (control), 50 and 100 mg L-1 at 30 days after planting. In general, results indicated that spraying plants with boric acid had a significant effect on yield, frui...

The reaction of Np(V) chloride with molten boric acid results in the disproportionation of Np(V) into Np(IV) and Np(VI), and the crystallization of K(2)[(NpO(2))(3)B(10)O(16)(OH)(2)(NO(3))(2)]. UV-vis-NIR spectroscopy demonstrates that in addition to the Np(VI) and Np(V) found in the crystal structure, Np(IV) is also present.

In order to study the effects of micronutrients zinc (Zn) and boron (B) foliar application on seed yield, yield components, seed oil and protein content and growth indices of canola (Brassica napus cv okapi), a field experiment was conducted during 2008 growing season. The experiment was a factorial with sixteen treatments and three replications on the basis of a completely randomized block de...

Freeze-dried, granular sugar baits containing boric acid as the toxicant were evaluated against house flies, Musca domestica L., in two bioassays with toxicant dose ranges of 3, 5, 7, 8, and 12%, and 3, 5, 9, 17, and 33% boric acid, respectively, calculated and expressed on a dry weight basis. Flies in bioassay 1 were mixed sex and unstarved and flies in bioassay 2 were females only and starved...

Background: Vulvovaginal candidiasis is one of the most common infections in gynecologic filed, and non–albicans Candida species are emerging causative microorganisms. This species shows resistance to routine treatments. One of the suggested treatments is administration of vaginal suppositories of boric acid. The aim of the present study was to compare boric acid with clotrimazole in the treatm...

In June 2010, the European Chemicals Agency (ECHA) added boric acid to the candidate list of SVHCs (substances of very high concern) under the Registration, Evaluation, Authorization and Restriction of Chemicals (REACH) Regulation. In polarizing plates, only unreacted (free) boric acid which is not bound to PVA is considered to be an SVHC. We developed a quantitative analytical method for unrea...

Populations maintain considerable segregating variation in the response to toxic, xenobiotic compounds. To identify variants associated with resistance to boric acid, a commonly-used household insecticide with a poorly understood mechanism of action, we assayed thousands of individuals from hundreds of strains. Using the Drosophila Synthetic Population Resource (DSPR), a multi-parental populati...

The structure of the title compound, catena-poly[[[di-μ-aqua-μ-fumarato-μ-(boric acid)-disodium]-di-μ-aqua] boric acid monosolvate], contains two crystallographically independent Na(+) cations, each being six-coordinated by one fumarate O atom, one boric acid O atom and four water O atoms in a distorted octa-hedral geometry. Adjacent [NaO(2)(OH(2))(4)] units share edges and are linked into chai...
