A pot experiment was carried out using soils mixed with CaCO3 in the size of > 0.02, 0.2,
2.0 and 5.0 mm. diameters of CaCO3 particles. Each size was representing 40% CaCO3
for all solis. Wheat and bean plants were planted and applied with constant doses of fertilizers. Fresh and oven dried weights were recorded and tissues were chemically analyzed for phosphorus and potassium. Results could be summarized in the followings. Wheat seeds were bad affected by fineness in germination while horse-bean plants were less affected due to its strongth of seedlings. For wheat plants treatments of 0.2 and 2.0 mm. CaCO3 sizes were the best followed by the coatser sizes (50 mm.) and the lowest were those of the finest size. Horse-bean plants were of stronger roots to grow easier in relatively coarser sizes of CaCo3. This was true also in regard of phosphorus and potassium concentrations in wheat and -bean plants and their total content per pot orf each soil treatment. Thus it could be recommended that plants of strong seeds must be initially cultivated in calcareous soils to face the first environmental conditions. Therefore, finer crop seeds could be cultivated when the soil surfaces take the stable shape of particles either by coagulating the fine ones or by filling the wide pore sapces of coarse CaCO3 particles by humus. |

Monoterpenes are a highly diverse group of chemical scents that originate from plant secondary metabolic processes, one purpose of which is to serve as a defense against herbivores. Plant-derived monoterpenes pro- duced from Lamiaceae species have demonstrated acaricidal activity against pest mites and ticks. However, the mechanism by which these compounds carry out the demise of this group of arachnids is poorly understood. Here, we review the chemistry and bioactivity of these promising compounds and subsequently assess their potential toxicity to mites and ticks through measurement of their docking ability to amino acid residues of the binding pocket of Drosophila melanogaster acetylcholinesterase (AChE). We identified 27 monoterpenes of the Lamiaceae family from the literature that were effective against mite (Varroidae, Tetranychidae, Eriophyidae) and tick (Ixodidae) species that are problematic in agricultural production. Screening of these compounds showed that monoterpenoids possessing methyl groups, such as carvacrol, linalool, ?-terpineol, bornyl acetate, and terpine-4-ol, strongly bind to D. melanogaster AChE. Linalool, which fits into the binding pocket in the amino acid catalytic triad of AChE (oxyanion hole residues, hydrogen bond interaction with GLU 237, and anionic binding with TRP 83), was identified as the most promising target for further optimization studies. We propose that monoterpenes which interact strongly with amino acid residues of the AChE receptor be targeted for development of effective, naturally produced biocontrol pesticides, as this model demonstrates potential for discovery of new acaricide compounds in a high throughput manner MenosMonoterpenes are a highly diverse group of chemical scents that originate from plant secondary metabolic processes, one purpose of which is to serve as a defense against herbivores.
