Aerial Application
Aerial application, or crop dusting, involves spraying crops with crop protection products from an agricultural aircraft. Planting certain types of seed are also included in aerial application. The specific spreading of fertilizer is also known as ''aerial topdressing ''in some countries. Many countries have severely limited aerial application of pesticides and other products because of environmental and public health hazards like Pesticide drift, spray drift; most notably, the European Union banned it outright with a few highly restricted exceptions in 2009, effectively ending the practice in all member states. Agricultural aircraft are highly specialized, purpose-built aircraft. Today's agricultural aircraft are often powered by turbine engines of up to and can carry as much as of crop protection product. Helicopters are sometimes used, and some aircraft serve double duty as water bombers in areas prone to wildfires. These aircraft are referred to as SEAT, or "single engine ai ...

Curtiss JN Jenny
The Curtiss JN "Jenny" is a series of biplanes built by the Glenn Curtiss Aeroplane Company of Hammondsport, New York, later the Curtiss Aeroplane and Motor Company. Although the Curtiss JN series was originally produced as a training aircraft for the US Army, the "Jenny" (the common nickname derived from "JN") continued after World War I as a civilian aircraft, becoming the "backbone of American postwar [civil] aviation". Thousands of surplus Jennys were sold at bargain prices to private owners in the years after the war, and became central to the barnstorming era that helped awaken the US to civil aviation through much of the 1920s. Design and development Curtiss combined the best features of the Curtiss Model J, model J and Curtiss Model N, model N Training aircraft, trainers, built for the United States Army, US Army and United States Navy, US Navy, and began producing the JN or "Jenny" series of aircraft in 1915. Curtiss built only a limited number of the JN-1 and JN-2 bipl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fungicide
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insecticide
Insecticides are pesticides used to kill insects. They include ovicides and larvicides used against insect eggs and larvae, respectively. The major use of insecticides is in agriculture, but they are also used in home and garden settings, industrial buildings, for vector control, and control of insect parasites of animals and humans. Acaricides, which kill mites and ticks, are not strictly insecticides, but are usually classified together with insecticides. Some insecticides (including common bug sprays) are effective against other non-insect arthropods as well, such as scorpions, spiders, etc. Insecticides are distinct from insect repellents, which repel but do not kill. Sales In 2016 insecticides were estimated to account for 18% of worldwide pesticide sales. Worldwide sales of insecticides in 2018 were estimated as $ 18.4 billion, of which 25% were neonicotinoids, 17% were pyrethroids, 13% were diamides, and the rest were many other classes which sold for less th ...

Catalpa
''Catalpa'' (, ), commonly also called catawba, is a genus of flowering plants in the family Bignoniaceae, native to warm temperate and subtropical regions of North America, the Caribbean, and East Asia. Description Most ''Catalpa'' are deciduous trees; they typically grow to tall, with branches spreading to a diameter of about . They are fast growers and a 10-year-old sapling may stand about tall. They have characteristic large, heart-shaped leaves, which in some species are three-lobed. The appearance of the leaves sometimes causes confusion with species such as the unrelated tung tree ('' Vernicia fordii'') and ''Paulownia tomentosa''. ''Catalpa'' species bear broad panicles of showy flowers, generally in summer. The flower colour generally is white to yellow. In late summer or autumn the fruit appear; they are siliques about long, full of small flat seeds, each with two thin wings to aid in wind dispersal. The large leaves and dense foliage of ''Catalpa'' species provid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caterpillars
Caterpillars ( ) are the larval stage of members of the order Lepidoptera (the insect order comprising butterflies and moths). As with most common names, the application of the word is arbitrary, since the larvae of sawflies (suborder Symphyta) are commonly called caterpillars as well. Both lepidopteran and symphytan larvae have eruciform body shapes. Caterpillars of most species eat plant material ( often leaves), but not all; some (about 1%) eat insects, and some are even cannibalistic. Some feed on other animal products. For example, clothes moths feed on wool, and horn moths feed on the hooves and horns of dead ungulates. Caterpillars are typically voracious feeders and many of them are among the most serious of agricultural pests. In fact, many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce, whereas the moths are obscure and do no direct harm. Conversely, various species of caterp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceratomia Catalpae
''Ceratomia catalpae'', the catalpa sphinx, is a hawk moth of the family Sphingidae. The species was first described by Jean Baptiste Boisduval in 1875. Other common names are the Catawba worm, or Catalpa sphinx. Range ''Ceratomia catalpae'' is a native of southeastern North America and can be located on catalpa trees that grow within this region. It can be found from Maine, west to Iowa, south to Florida, the Gulf States and Texas. Life cycle From oviposition of the eggs to pupation, about four weeks will pass. Where multiple broods occur, pupae will eclose in two weeks, or when conditions are suitable. Adult ''C. catalpae'' do not reflect the wonderful colors of their larvae. They are a dull brown color lacking the show-off appearance of its larval stages. Egg Translucent, milky-white, green, or yellowish eggs are oval, being about 0.5 mm in diameter. Eggs are deposited in masses of 100-1000 eggs on the undersurface of leaves, while smaller masses are deposited onto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lead Arsenate
Lead hydrogen arsenate, also called lead arsenate, acid lead arsenate or LA, chemical formula PbHAsO4, is an inorganic insecticide formerly used to control pests including gypsy moth, potato beetle and rats. Lead arsenate was the most extensively used arsenical insecticide.Peryea F.J. 1998. Historical use of lead arsenate insecticides, resulting in soil contamination and implications for soil remediation. Proceedings, 16th World Congress of Soil Science, Montpellier, France. 20-26. Aug. Available online: http://soils.tfrec.wsu.edu/leadhistory.htm Two principal formulations of lead arsenate were marketed: basic lead arsenate (Pb5OH(AsO4)3, CASN: 1327-31-7) and acid lead arsenate (PbHAsO4). It is now banned for use as a pesticide in countries such as the US and UK as it is considered too toxic and persistent. Production and structure It is usually produced using the following reaction, which leads to formation of the desired product as a solid precipitate: :Pb(NO3)2 + H3AsO4 � ...
