Propiconazole
Propiconazole is a triazole fungicide, also known as a DMI, or demethylation inhibiting fungicide due to its binding with and inhibiting the Lanosterol 14 alpha-demethylase, 14-alpha demethylase enzyme from demethylating a precursor to ergosterol. Without this demethylation step, the ergosterols are not incorporated into the growing fungal cell membranes, and cellular growth is stopped. Agriculture Propiconazole is used agriculturally as a systemic fungicide on turfgrasses grown for seed and aesthetic or athletic value, wheat, mushrooms, corn, wild rice, peanuts, almonds, sorghum, oats, pecans, apricots, peaches, nectarines, plums, prunes and lemons. It is also used in combination with permethrin in formulations of wood preserver. Propiconazole is a mixtureL. Toribio, M. J. del Nozal, J. L. Bernal, J. J. Jeménez und C. Alonso,'' J.

Anthrenocerus Australis
''Anthrenocerus australis'', commonly known as the Australian carpet beetle, is a species of beetle belonging to the Dermestidae family. It is one of the most researched of the thirty-one species in the genus Anthrenocerus. This is generally attributed to its prevalence throughout Australia and New Zealand and the negative economic and agricultural impact it has as a pest. It is the larvae that causes damage to products, not the adult beetle. The total Biological life cycle, life cycle of this insect is around three years, most of which is spent as a larva. Once the beetle reaches maturity, it only lives for between two and six weeks. Physical description The adult ''A. australis'' is a dark brown and black oval beetle, which grows to be around 2.2-2.5mm long. At the front of the head are two small eyes and a pair of Antenna (biology), antennae. Below are six outward facing legs and a mouth. The back of the beetle's body has a hardened shell to provide protection for the delicat ...

Triazole
A triazole is a heterocyclic compound featuring a five-membered ring of two carbon atoms and three nitrogen atoms with molecular formula C2H3N3. Triazoles exhibit substantial Isomer, isomerism, depending on the positioning of the nitrogen atoms within the ring. Many triazoles are versatile, biologically active compounds commonly used as fungicides and plant retardants. However, triazoles are also useful in bioorthogonal chemistry, because the large number of nitrogen atoms causes triazoles to react similar to Azide, azides. Lastly, the many free lone pairs in triazoles make them useful as coordination compounds, although not typically as Piano stool complex, haptic ligands. Isomerism There are four triazole isomers, which are conventionally divided into two pairs of Tautomer, tautomers. In the 1,2,3-Triazole, 1,2,3-triazoles, the three nitrogen atoms are adjacent; in the 1,2,4-Triazole, 1,2,4-triazoles, an interstitial carbon separates out one nitrogen atom. Each category ...

Peaches
The peach (''Prunus persica'') is a deciduous tree first domesticated and cultivated in China. It bears edible juicy fruits with various characteristics, most called peaches and the glossy-skinned, non-fuzzy varieties called nectarines. Peaches and nectarines are the same species, though they are regarded commercially as different fruits. The tree is regarded as handsome and is planted in gardens for its springtime blooms in addition to fruit production. The peach tree is relatively short lived, usually not exceeding twenty years of age. However, the peach fruit is regarded as a symbol of longevity in several East Asian cultures. The specific name ''persica'' refers to its widespread cultivation in Persia (modern-day Iran), from where it was transplanted to Europe and in the 16th century to the Americas. It belongs to the genus ''Prunus'', which also includes the cherry, apricot, almond, and plum, and which is part of the rose family. The peach is very popular; only the ...

Fungicides
Fungicides are pesticides used to kill parasitic fungi or their spores. Fungi can cause serious damage in agriculture, resulting in losses of yield and quality. Fungicides are used both in agriculture and to fight fungal infections in animals, including humans. Fungicides are also used to control oomycetes, which are not taxonomically/genetically fungi, although sharing similar methods of infecting plants. Fungicides can either be contact, translaminar or systemic. Contact fungicides are not taken up into the plant tissue and protect only the plant where the spray is deposited. Translaminar fungicides redistribute the fungicide from the upper, sprayed leaf surface to the lower, unsprayed surface. Systemic fungicides are taken up and redistributed through the xylem vessels. Few fungicides move to all parts of a plant. Some are locally systemic, and some move upward. Most fungicides that can be bought retail are sold in liquid form, the active ingredient being present at 0.08% i ...

Aromatase Inhibitors
Aromatase inhibitors (AIs) are a class of medication, drugs used in the treatment of breast cancer in menopause, postmenopausal women and in men, and gynecomastia in men. They may also be used off-label to reduce estrogen conversion when supplementing testosterone exogenously. They may also be used for chemoprevention in women at high risk for breast cancer. Aromatase is the enzyme that catalyzes a key aromatization step in the synthesis of estrogen. It converts the Alpha-beta Unsaturated carbonyl compounds, enone ring of androgen precursors such as testosterone, to a phenol, completing the synthesis of estrogen. As such, AIs are estrogen synthesis inhibitors. Because hormone-positive breast and ovarian cancers are dependent on estrogen for growth, AIs are taken to either block the production of estrogen or block the action of estrogen on receptors. Medical uses Cancer In contrast to premenopausal women, in whom most of the estrogen is produced in the ovary, ovaries, in postmeno ...

Stereoisomer
In stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space. This contrasts with structural isomers, which share the same molecular formula, but the bond connections or their order differs. By definition, molecules that are stereoisomers of each other represent the same structural isomer. Enantiomers Enantiomers, also known as optical isomers, are two stereoisomers that are related to each other by a reflection: they are mirror images of each other that are non-superposable. Human hands are a macroscopic analog of this. Every stereogenic center in one has the opposite configuration in the other. Two compounds that are enantiomers of each other have the same physical properties, except for the direction in which they rotate polarized light and how they interact with different enantiomers of ...

Permethrin
Permethrin is a medication and an insecticide. As a medication, it is used to treat scabies and lice. It is applied to the skin as a cream or lotion. As an insecticide, it can be sprayed onto outer clothing or mosquito nets to kill the insects that touch them. Side effects include rash and irritation where it is Topical medication, applied. Use during pregnancy appears to be safe, and it is approved for use on and around people over the age of two months in the United States. Permethrin is in the pyrethroid family of medications. It works by disrupting the function of the neurons of lice and scabies mites. Permethrin was discovered in 1972. It is on the WHO Model List of Essential Medicines, World Health Organization's List of Essential Medicines. In 2022, it was the 351st most commonly prescribed medication in the United States, with more than 40,000 prescriptions.

Prunes
A prune is a dried plum, most commonly from the European plum (''Prunus domestica'') tree. Not all plum species or varieties can be dried into prunes. Use of the term ''prune'' for fresh plums is obsolete except when applied to varieties of plum grown for drying. In this usage, a prune is the firm-fleshed plum fruit of ''P. domestica'' varieties that have a high soluble solids content, and do not ferment during drying. Most prunes are ''freestone'' cultivars (i.e., the pit is easy to remove), whereas most plums grown for fresh consumption are ''clingstone'' (the pit is more difficult to remove). The sorbitol content of dietary fiber likely provides the laxative effect associated with consuming prunes. Prunes are 64% carbohydrates, including dietary fiber, 2% protein, a rich source of vitamin K, and a moderate source of B vitamins and dietary minerals. Production More than 1,000 plum cultivars are grown for drying. The main cultivar grown in the United States is the 'Improv ...

Plums
A plum is a fruit of some species in ''Prunus'' subg. ''Prunus''''.'' Dried plums are often called prunes, though in the United States they may be labeled as 'dried plums', especially during the 21st century. Plums are likely to have been one of the first fruits domesticated by humans, with origins in East European and Caucasian mountains and China. They were brought to Britain from Asia, and their cultivation has been documented in Andalusia, southern Spain. Plums are a diverse group of species, with trees reaching a height of when pruned. The fruit is a drupe, with a firm and juicy flesh. China is the largest producer of plums, followed by Romania and Serbia. Japanese or Chinese plums dominate the fresh fruit market, while European plums are also common in some regions. Plums can be eaten fresh, dried to make prunes, used in jams, or fermented into wine and distilled into brandy. Plum kernels contain cyanogenic glycosides, but the oil made from them is not commerci ...

Apricots
An apricot (, ) is a fruit, or the tree that bears the fruit, of several species in the genus ''Prunus''. Usually an apricot is from the species '' P. armeniaca'', but the fruits of the other species in ''Prunus'' sect. ''Armeniaca'' are also called apricots. In 2022, world production of apricots was 3.9 million tonnes, led by Turkey with 21% of the total. Etymology ''Apricot'' first appeared in English in the 16th century as ''abrecock'' from the Middle French or later , from Spanish '' albaricoque'' and Catalan , in turn from Arabic (, ), from Byzantine Greek (, ), derived from late Greek (, ) from Latin () (, ). Description The apricot is a small tree, tall, with a trunk up to in diameter and a dense, spreading canopy. The leaves are ovate, long, and wide, with a rounded base, a pointed tip, and a finely serrated margin. The flowers are in diameter, with five white to pinkish petals; they are produced singly or in pairs in early spring before the leaves. T ...
