Rice pests and diseases and pesticide control
Rice is an important field crop in China, so the problem of rice pests and diseases has also attracted people's attention. This article will introduce in detail the treatment methods of rice pests and diseases, and I hope to help everyone.
Rice, like humans, can get sick. Pests and diseases are the main culprit influencing the growth and harvest of a season of crops. The screaming seedlings that have been inserted, the management of Miaotian has the contents of fertilization, pest control, and weeding in the fields. The hard work of the farmer is only known to the farmers themselves. Just as Tang Shiyun: "When the day of the Wohe Day, the sweat dripped down the soil. Who knows the Chinese food, the grains are hard." But if you encounter the disease and the severe years, everything is white and hard.
Chilo suppressalis is a rice borer. In the evening, people put lights on the field, put a basin of water under the lamp, and the water is filled with waste oil. When the pests are thrown into the water, they will not fly and drown in the water. This method of pest control is environmentally friendly as it is now. There is no chemical pesticide to pollute the environment, but unfortunately the effect is too low, and the effect is minimal...
The name "oilworm" is not found in the agricultural book. The "oilworm" growing on vegetables is actually a locust. The method of treating the "oilworm" is the old foundation that has been followed. The field is full of water, each person takes a bottle of vegetable oil, or goes to the oil workshop to buy oil feet, dripping into the paddy field, and dragging with the feet. Stir the water, the purpose is to let the oil spread out, fill the water surface between the line spacing, which is called dragging oil. It is said that the "oilworm" will drown when it is caught by oil when it comes to drinking water.
Later, I knew that this small insect crawling in the lower part of the rice stem cluster was called rice planthopper. It uses a needle-shaped mouthparts to pierce the stems of rice to suck the juice, while sucking, it secretes a toxic substance to destroy the rice stem tissue, which causes many brown spots on the stem of the crop. Rice that was damaged early did not heading, and rice with late damage was less than grain. Rice planthoppers lay eggs in the stalk tissue, hindering the transport of nutrients in rice, making the rice leaves sallow and the stems become black and withered. When you encounter this kind of insect rice, look at a paddy rice and harvest a grass. I clearly remember that there was a piece of more than six acres of old green late rice, because the insects turned yellow, and after harvesting, the straw was tied together, and a three-ton head-up wooden boat was loaded with a large boat.
There are also many pests on crops, such as rice locusts, mites and mites, and many diseases, such as stalks and bacterial blight. There is no way to cure without pesticides .
Later, with pesticides, there were "two two three" and "six six six" powders, which belonged to organochlorine pesticides. According to the investigation: As early as 1936, a doctor named Dr. Muller discovered and synthesized the insecticide miracle DDT in Switzerland, and won the Nobel Prize in Chemistry in 1945.
The "six six six" powder, the scientific name of HCH, is said to have been invented by the Americans. China was successfully trial-produced at the Qingdao Chemical Plant in Shandong in 1968. Hangzhou Pesticide Factory successfully synthesized the "two two three" emulsion in 1970. Since then, agricultural crops have included rice, and a large number of chemical pesticides have been used as insecticides. With the development of science, the birth of organophosphorus pesticides, these broad-spectrum highly toxic organophosphorus pesticides have gradually replaced organochlorine pesticides. In the 1980s, the "6-6" powder and the "2 2 3" emulsion were banned from production and use, ending the history of organochlorine pesticides.
There are no fewer than a dozen kinds of pests and diseases in rice. Various targeted pesticides are continuously introduced, and more and more pesticides are being used for guidance. The output of crops including rice is increasing year by year. According to the data in the 1980s, after using chemical pesticides to control harmful organisms, more than 32 million tons of grain can be recovered each year.
