The two major criticisms are the run off of fertiliser into streams and waterways encourages marine plant growth, leading to choking of the waterways, and altering the fresh water ecosystem, disadvantaging many fish, (and frustrating anglers). To minimise impact, topdressing is now prohibited within certain distances of water. The second impact is less direct. By enabling sheep to be run profitably on steep ...

History of aerial topdressing in New Zealand - Great Britian.
Faced with far greater difficulty operating aircraft from small British farms, the British Government assumed topdressing aircraft would need to operate from an ordinary runway. Economies of scale then dictated using large aircraft, which would in turn have to fly higher. ...

| | | | | fungicides: Encyclopedia II - Magnaporthe grisea - Distribution Rice blast was probably first recorded as rice fever disease in China in 1637. It was later described as imochi-byo in Japan in 1704, and as brusone in Italy in 1828. The fungus is currently reported to be present in at least 85 countries. In 1996 rice blast was found in rice in California, and has since been found in grasses on golf courses in the midwestern United States.
Strains of the fungus can infect domesticated grasses such as barley, wheat, rye, pearl millet, and turf grasses in addition to rice. Thus, ev ...

| | | | | fungicides: Encyclopedia II - Wheat - History Domestic wheat originated in southwest Asia in what is now known as the Fertile Crescent. The earliest archaeological evidence for wheat cultivation comes from Syria, Jordan, Turkey, and Iraq. Around 10,000 years ago, wild einkorn and emmer wheat were domesticated as part of the origins of agriculture in the fertile crescent. Cultivation of wild forms led to selection of mutations for tough-rachised ears (which do not break up at maturity) and larger grains (see domestication). While these forms could not have succeeded in the wild, under cultivation they produced more food for humans.
The cultivation of wheat began to spread into Europe b ...

| | | | | fungicides: Encyclopedia II - Wheat - Genetics & Breeding Wheat genetics is more complicated than domesticated animal genetics. Wheat is capable of polyploidy, or having more than two sets of chromosomes (diploid). A further complicating factor is that four out of five of the most common wheat species are the results of hybridization.
Einkorn wheat is diploid (2x chromosomes). The tetraploid wheats (e.g. emmer and durum wheat) derive from wild emmer, Triticum dicoccoides. Wild emmer is the result of a hybridisation between two diploid wild grasses, T. urartu and a wild goatgras ...

| | | | | fungicides: Encyclopedia II - Wheat - Hulled vs. free-threshing wheat All four wild species of wheat, and in the domesticated einkorn, emmer and spelt wheats are hulled (in German, Spelzweizen). This more primitive morphology consists of toughened glumes that tightly enlose the grains, and (in domesticated wheats) a semi-brittle rachis that breals easily on threshing. The result is that when threshed, the wheat ear breaks up into spikelets. To obtain the grain, further processing, such as milling or pounding, is needed to remove the hulls or husks. In contrast, in free-threshing (or naked) forms such as ...

| | | | | fungicides: Encyclopedia II - Sulfur - Precautions Carbon disulfide, Carbon oxysulfide, hydrogen sulfide, and sulfur dioxide should all be handled with care.
Although sulfur dioxide is sufficiently safe to be used as a food additive in small amounts, at high concentrations it reacts with moisture to form sulfurous acid which in sufficient quantities may harm the lungs, eyes or other tissues. In creatures without lungs such as insects or plants, it otherwise prevents respiration.
Hydrogen sulfide is quite toxic (more toxic than cyanide). Although very smelly at first, it quickly deadens the sense of smell, so potential victims may be unaware ...

| | | | | fungicides: Encyclopedia II - Sulfur - Isotopes Sulfur has 18 isotopes, of which four are stable: 32S (95.02%), 33S (0.75%), 34S (4.21%), and 36S (0.02%). Other than 35S, the radioactive isotopes of sulfur are all short lived. Sulfur-35 is formed from cosmic ray spallation of argon-40 in the atmosphere. It has a half-life of 87 days.
When sulfide minerals are precipitated, isotopic equilibration among solids and liquid may cause small differences in the dS-34 values of co-genetic minerals. The differences between minerals can b ...

| | | | | fungicides: Encyclopedia II - Sulfur - Occurrence Elemental sulfur can be found near hot springs and volcanic regions in many parts of the world, especially along the Pacific Ring of Fire. These occurrences are the basis for the traditional name brimstone, since sulfur could be found near the brims of volcanic craters. Such volcanic deposits are currently exploited in Indonesia, Chile, and Japan.
Significant desposits of elemental sulfur also exist in salt domes along the coast of the Gulf of Mexico, and in evaporites in eastern Europe and western Asia. The sulfur in these deposits i ...

| | | | | fungicides: Encyclopedia II - Agriculture - History Archaeobotanists have traced the selection and cultivation of specific food plant characteristics, such as a semi-tough rachis and larger seeds, to just after the Younger Dryas (about 9,500 BC) in the early Holocene in the Levant region of the Fertile Crescent. Limited anthropological and archaeological evidence both indicate a grain-grinding culture farming along the Nile in the 10th millennium BC using the world's earliest known type of sickle blades. There is even earlier evidence for conscious cultivation and seasonal harvest: grains of ...

| | | | | fungicides: Encyclopedia II - Wheat - Naming There are many taxonomic classification systems used for wheat species. It is good to keep in mind that the name of a wheat species from one information source may not be the name of a wheat species in another information source. [1] Wheat forms are classified by growing season, such as winter wheat vs. spring wheat, and by gluten content, such as hard wheat (high gluten content) or soft wheat (high starch content).

| | | | | fungicides: Encyclopedia II - Wheat - Economics Harvested wheat grain is classified according to grain properties (see below) for the purposes of the commodities market. Wheat buyers use the classifications to help determine which wheat to purchase as each class has special uses. Wheat producers determine which classes of wheat are the most profitable to cultivate with this system.
Wheat is widely cultivated as a cash crop because it produces a good yield per unit area, grows well in a temperate climate even with a moderately short growing season, and yields a versatile, high-quali ...

Wheat - Crop development.
Crop management decisions require the knowledge of stage of development of the crop. In particular, spring fertilizers applications, herbicides, fungicides, growth regulators are typically applied at specific stages of plant development.
For example, current recommendations often indicate the second application of nitrogen be done when the ear (not visible at this stage) is about 1 cm in size (Z31 on Zadoks scale). Knowledge of stages is also interesting to identify periods of hig ...

| | | | | fungicides: Encyclopedia II - Sulfur - History Sulfur (Sanskrit, sulvere; Latin sulpur) was known in ancient times, and is referred to in the Biblical Pentateuch (Genesis). English translations of this commonly refer to sulfur as "brimstone", giving rise to the name of 'Fire and brimstone' sermons, which are sermons where hell and eternal damnation for sinners is stressed. It is from this part of the Bible that hell is thought to smell of sulfur. The word itself is almost certainly from the Arabic sufra meaning yellow, from the bright colo ...
