What is APSA-80? APSA-80‚ a product of Amway is an all purpose spray adjuvant which on mixing with insecticides‚ fungicides‚ herbicides and defoliators increases their efficacy. As a result of that‚ the crops‚ fruits and vegetable are better protected from diseases‚ pests and unwanted herbs‚ resulting in more productive yield. This adjuvant has 80% of active ingredients and this can be mixed in any solution to improve its performance many times Note : APSA-80 is neither an insecticide nor a fertiliser

Thermal Runaway Reactions Plan Hypothesis: In this experiment‚ my hypothesis is that‚ the more concentrated acid there is‚ the bigger the temperature change in the experiment. This is because there are more acid particles to collide & react with each other. Equipment: * Beaker (100cm3) * Assorted measuring cylinders * Stopwatch * Thermometer * 0.1g of magnesium powder * 10cm3 of sulphuric acid Method: First‚ I will measure the correct amount of magnesium I need‚

Fusarium wilt caused by Fusarium oxysporum f.sp. ciceris is a soil and seed borne disease affecting chickpea whichis widely distributed where chickpea is grown. It causes yield losses in the range of 12 to 100 % depending on the level of resistance of the genotype and suitability of environmental conditions for disease development. Management of soil borne diseases mainly involves use of preventive measures because it is harder to control the disease once established. Thiram and carbendazim are used

Acid Rain Acid rain occurs when Sulphur Dioxide (SO2) is released into the atmosphere by electricity generation‚ motor vehicles‚ factories and by wildfires and volcanoes. Once released‚ the sulphur dioxide reacts with water to produce sulphuric acid. This has a pH of approximately 2-3 pH. This has a dramatic effect on water dwelling wildlife. Most water dwelling creatures can’t withstand water more acidic than pH 5. This causes the mass loss of life of animals such as trout‚ perch‚ frogs and mayflies

Environmental effects of copper Copper can be released into the environment by both natural sources and human actions. Examples of natural sources are wind-blown dust‚ decaying vegetation‚ forest fires and sea spray. Other examples are mining‚ metal production‚ wood production and phosphate fertilizer production. Because copper is released both naturally and through human activity it is very widespread in the environment. Copper is often found near mines‚ industrial settings‚ landfills and waste
