White Oil
White oil is an insecticide spray used for controlling a wide range of insect pests in the garden. The spray works by blocking the breathing pores of insects, causing suffocation and death. It is effective in the control of aphids, scale, mealybug, mites, citrus leaf miner, and smooth skinned caterpillars. "White oil" is also an alternative name for mineral oil. Commercial organic pesticide White oil is sold commercially as a petroleum oil-based organic pesticide, in both a concentrate, and ready-to-use spray bottle or can. The term "horticultural oil" may be used to differentiate this petroleum oil-based product from home made products using vegetable oil. DIY recipe The quantities vary depending on the source, but a common concentrate typical mixture is 4 parts of vegetable oil (a non-mineral oil) to one part of liquid dish-washing soap/detergent (for washing by hand). It may be blended in a mixer or shaken by hand in a jar or bottle until homogeneous to be stored. Use Co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aphids
Aphids are small sap-sucking insects and members of the superfamily Aphidoidea. Common names include greenfly and blackfly, although individuals within a species can vary widely in color. The group includes the fluffy white woolly aphids. A typical life cycle involves flightless females giving live birth to female nymphs—who may also be already pregnant, an adaptation scientists call telescoping generations—without the involvement of males. Maturing rapidly, females breed profusely so that the number of these insects multiplies quickly. Winged females may develop later in the season, allowing the insects to colonize new plants. In temperate regions, a phase of sexual reproduction occurs in the autumn, with the insects often overwintering as eggs. The life cycle of some species involves an alternation between two species of host plants, for example between an annual crop and a woody plant. Some species feed on only one type of plant, while others are generalists, coloni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scale Insect
Scale insects are small insects of the order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the infraorder Coccomorpha which is considered a more convenient grouping than the superfamily Coccoidea due to taxonomic uncertainties. Adult females typically have soft bodies and no limbs, and are concealed underneath domed scales, extruding quantities of wax for protection. Some species are hermaphroditic, with a combined ovotestis instead of separate ovaries and testes. Males, in the species where they occur, have legs and sometimes wings, and resemble small flies. Scale insects are herbivores, piercing plant tissues with their mouthparts and remaining in one place, feeding on sap. The excess fluid they imbibe is secreted as honeydew on which sooty mold tends to grow. The insects often have a mutualistic relationship with ants, which feed on the honeydew and protect them from predators. There are about 8,000 descr ...

Mealybug
Mealybugs are insects in the family (biology), family Pseudococcidae, unarmored scale insects found in moist, warm habitats. Many species are considered pest (animal), pests as they feed on plant juices of greenhouse plants, house plants and subtropical trees and also act as a vector (epidemiology), vector for several plant diseases. Some ants live in symbiotic Ant#Relationships with other organisms, relationships with them, protecting them from predators and feeding off the Honeydew (secretion), honeydew which they excrete. Description Mealybugs are Sexual dimorphism, sexually dimorphic: females appear as nymphs, exhibiting reduced morphology, and lack wings, although unlike many female scale insects, they often retain legs and can move. Males are smaller, gnat-like and have wings. Since mealybugs (as well as all other Hemiptera) are hemimetabolous insects, they do not undergo complete metamorphosis in the true sense of the word. However, male mealybugs do exhibit a radical cha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mites
Mites are small arachnids (eight-legged arthropods). Mites span two large orders of arachnids, the Acariformes and the Parasitiformes, which were historically grouped together in the subclass Acari, but genetic analysis does not show clear evidence of a close relationship. Most mites are tiny, less than in length, and have a simple, unsegmented body plan. The small size of most species makes them easily overlooked; some species live in water, many live in soil as decomposers, others live on plants, sometimes creating galls, while others again are predators or parasites. This last type includes the commercially destructive ''Varroa'' parasite of honey bees, as well as scabies mites of humans. Most species are harmless to humans, but a few are associated with allergies or may transmit diseases. The scientific discipline devoted to the study of mites is called acarology. Evolution and taxonomy The mites are not a defined taxon, but is used for two distinct groups of arachnids ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Citrus Leaf Miner
''Citrus'' is a genus of flowering trees and shrubs in the rue family, Rutaceae. Plants in the genus produce citrus fruits, including important crops such as oranges, lemons, grapefruits, pomelos, and limes. The genus ''Citrus'' is native to South Asia, East Asia, Southeast Asia, Melanesia, and Australia. Various citrus species have been used and domesticated by indigenous cultures in these areas since ancient times. From there its cultivation spread into Micronesia and Polynesia by the Austronesian expansion (c. 3000–1500 BCE); and to the Middle East and the Mediterranean (c. 1200 BCE) via the incense trade route, and onwards to Europe and the Americas. History Citrus plants are native to subtropical and tropical regions of Asia, Island Southeast Asia, Near Oceania, and northeastern Australia. Domestication of citrus species involved much hybridization and introgression, leaving much uncertainty about when and where domestication first happened. A genomic, phylogenic, and b ...

Mineral Oil
Mineral oil is any of various colorless, odorless, light mixtures of higher alkanes from a mineral source, particularly a distillate of petroleum, as distinct from usually edible vegetable oils. The name 'mineral oil' by itself is imprecise, having been used for many specific oils over the past few centuries. Other names, similarly imprecise, include 'white oil', 'paraffin oil', ' liquid paraffin' (a highly refined medical grade), (Latin), and 'liquid petroleum'. Most often, mineral oil is a liquid by-product of refining crude oil to make gasoline and other petroleum products. This type of mineral oil is a transparent, colorless oil, composed mainly of alkanes and cycloalkanes, related to petroleum jelly. It has a density of around . Nomenclature Some of the imprecision in the definition of the names used for mineral oil (such as 'white oil') reflects usage by consumers and merchants who did not know, and usually had no need of knowing, the oil's precise chemical makeup ...

Homogenization (chemistry)
Homogenization or homogenisation is any of several processes used to make a mixture of two mutually non-soluble liquids the same throughout. This is achieved by turning one of the liquids into a state consisting of extremely small particles distributed uniformly throughout the other liquid. A typical example is the homogenization of milk, wherein the milk fat globules are reduced in size and dispersed uniformly through the rest of the milk. Definition Homogenization (from "homogeneous;" Greek, ''homogenes'': ''homos,'' same + ''genos,'' kind) is the process of converting two immiscible liquids (i.e. liquids that are not soluble, in all proportions, one in another) into an emulsion (Mixture of two or more liquids that are generally immiscible). Sometimes two types of homogenization are distinguished: primary homogenization, when the emulsion is created directly from separate liquids; and secondary homogenization, when the emulsion is created by the reduction in size of droplets ...

Spray Bottle
A spray bottle is a bottle that can squirt, spray or mist fluids. History While spray bottles existed long before the middle of the 20th century, they used a rubber bulb which was squeezed to produce the spray; the quickly-moving air siphoned fluid from the bottle. The rapid improvement in plastics after World War II increased the range of fluids that could be dispensed, and reduced the cost of the sprayers because assembly could be fully automated. The Drackett company, manufacturers of Windex glass cleaner, was a leader in promoting spray bottles. Roger Drackett raised soybeans, converted the soybeans to plastic using technology purchased from Henry Ford, and was an investor in the Seaquist company, an early manufacturer of sprayers and closures. Initially, the brittle nature of early plastics required that sprayers be packaged in a cardboard box, and the sprayer inserted in the glass Windex bottle by the consumer. The cost in the manufacturing sprayers was also a factor; co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pesticide Application
Pesticide application refers to the practical way in which pesticides (including herbicides, fungicides, insecticides, or nematode control agents) are delivered to their ''biological targets'' (''e.g.'' pest organism, crop or other plant). Public concern about the use of pesticides has highlighted the need to make this process as efficient as possible, in order to minimise their release into the environment and human exposure (including operators, bystanders and consumers of produce). The practice of pest management by the rational application of pesticides is supremely multi-disciplinary, combining many aspects of biology and chemistry with: agronomy, engineering, meteorology, socio-economics and public health, together with newer disciplines such as biotechnology and information science. Decision making Optical data from satellites and from aircraft are increasingly being used to inform application decisions. Seed treatments Seed treatments can achieve exceptionally high ...

Gardening Australia
''Gardening Australia'' is an Australian lifestyle television program which suggests and promotes organic and environmentally friendly ways of gardening. It is created by the Australian Broadcasting Corporation and airs on ABC TV, in an hour-long weekly show each Friday evening. A monthly magazine, ''Gardening Australia'', was spawned by the show. History The series has its origins in 1969 as ''It's Growing'', with five minute segments broadcast ahead of the Sunday night news on ABT2 in Hobart. It was hosted by Peter Cundall, an experienced gardener with a passion for growing plants using organic methods. He had hosted a gardening talkback segment on ABC radio in Hobart since 1967. It was renamed ''Landscape'' in 1972 and extended to 15 minutes per episode. The format was adapted into ''Gardening Australia'' in 1990, broadcast nationally with the format expanded to 30 minutes per episode. It was still hosted by Cundall with other gardening experts from around Australia. Ste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
