About Poisonous Pants:
The plant is widely distributed in nature, is naturally an indispensable part, to provide food to humans, is also an important industrial raw materials. They are closely related to people's lives. But the chemical composition of the plants themselves, many toxic substances inadvertently come into contact with, it may cause a lot of illness and even death. Novels are often able to see the shadow of the plant, and to conduct a more detailed summary of the classification of toxic plants toxic ingredients in accordance with the plant. Many of which we are very familiar with that previously may not have learned of their toxicity.

Poisonous plants - toxic fungiIdentify poisonous fungi feather Lactarius toxic fungi, only 11 remember, receive expert guidance, observe the color, odor, touch and smell to see if the actual to understand. Edible mushrooms pay special attention to distinguish whether toxic.Folk have some method to identify poisonous mushrooms and edible mushrooms:Poisonous mushroom and more variety of color and beautiful: non-toxic mushroom showed mostly white or dark brown.2, the cap on the sarcoma, stipe on the loop and volva toxic; otherwise non-toxic.3, poisonous mushroom found growing in dirty, wet, rich in organic matter; non-toxic mushroom is grown in a clean place.Poisonous mushroom collection and easy to change, non-toxic mushrooms are difficult to change.Poisonous mushroom mostly soft and juicy, non-toxic mushrooms are more dense and fragile.6 poison mushroom juice muddy the clear water, non-toxic mushroom like milk.7, poisonous mushroom flavor and more bitterness of Kula, non-toxic mushroom is very delicious.8, cook mushrooms, poison mushrooms make silver utensils black, add milk, milk immediately solidified.However, these methods are not infallible. Mushroom shape, color, ecology and toxins are not necessarily linked. Some mushrooms are poisonous, but after washed, boiled, dried or cooked, toxicity will reduce or less.
Feed mushrooms always to follow the following principles:1 to avoid the long white gills and stem base the the volva (cyclic attached circle) as well as the carrier ring stem fungi. Any cut wounds umbrella fungi species are not to eat yellow fungus meat.2 avoid any fungi is corruption. Unless it can be confirmed that the edible species, otherwise throw away.Different types of germs cause different symptoms. Common symptoms are vomiting, diarrhea, extreme thirst, night sweats, cramps, dizziness, blindness, decreased body temperature.3 after eating poisonous mushrooms, you should try to eliminate the poison, available in warm salt water enema catharsis vomiting after poisoning, but also drink plenty of dilute brine or vomiting caused by the throat with a finger, with a 1% saline or the tea water repeatedly gastrolavage the, in order to avoid the body continues to absorb toxins.Edible wild plants and fungi than the cultivation of vegetables nutritional value, but do not risk being poisonous, best not distinguish toxic not toxic when to give up.
Poisonous plants - identification methodThe hydrangeas experts, in some of the new cell, and all kinds of colorful flowers and landscaping. For curious children, parents must teach them to stay away from poisonous plants. Such as wisteria, hydrangeas, daffodils, oleander, rhododendron and others have varying degrees of toxicity.
Considered incomplete poisonous plants, can remember several is: avoid the sense of plants in dry or spicy hot juice in contact with the skin or tongue; Do not collect any plants with milky white milky sap; Do not collected bright red plants; Do not go to the collection split into five shaped berries; collection has a tiny barbs on the stems and leaves of weeds or other plants best not; Do acquisition aging or withered leaves. And collected mature ferns Do (usually long in the dark and damp). There are many plants have large concentrations of toxic substances in the section of thick roots or bulbs, tubers, bulbs, etc. under the ground, such as narcissus bulbs.
Poisonous plants - alternative pesticides disinsectedHu vine According to FAO estimates, the pest allows grain yield losses of 20% to 40%, in order to deal with pests and diseases, global pesticide use up to 200 million tons per year. Long-term large-scale use of chemical pesticides, resulting in a large number of forestry health pests developed resistance to them. For example, Plutella resistance ratios of methyl 1605 is 21,000 times on methomyl 1049 times 6768 times the four deltamethrin.
Extensive use of chemical pesticides, not only exacerbate environmental pollution is directly endanger human health. Recently, the Ministry of Health announced that the very serious situation of food poisoning caused by pesticides in China last year, a total of 41 cases of poisoning incidents occurred, number 1311 poisoning death of 35 people. Therefore, the world of the production and use of chemical pesticides developed strict regulations, relevant organizations of the United Nations also issued a manual disable and restrict the use of 500 kinds of chemical pesticides.
In the face of a series of serious problems caused long-term unrestrained use of chemical pesticides, scientists from various countries from stepping up research poisonous plants and to promote the application of plant pesticides find a way out. Of plant pesticides also known as biological pesticides, poisonous plants in a variety of insecticidal components extracted from pesticides.
Compared to chemical pesticides, plant pesticides outstanding advantages:
Treats First it insecticidal active ingredient is a natural substance, after administration easier decomposed into non-toxic substances, less pollution to the environment. For example, "Derris cyanide" This insecticide, the use of ultra-high doses of spraying, after five days in the soil can not be detected toxic ingredients, toxic substances is also minimal residue on the vegetables, "the rational use of pesticides guidelines provisions allow the residual amount of 0.1% to 2.2%. Chemical pesticide DDT, the world has been disabled for 10 years, but we are in close contact with the land, waters and aquatic products, there is still a high content.
Diversification of plant insecticide insecticidal components, making pest resistance more difficult. Compatibility complex of traditional Chinese medicine with bacteria than a single component of the antibiotic harder to adapt is the same reason.
Safe plant pesticides on beneficial organisms (natural enemies of pests). According to the testing, the use of "Derris cyanide" the usual dose of the plant insecticide spraying, vegetables number one pest turnip aphid control effect reached 99.85%, while killing aphid natural enemies ladybug was only 11.58%.
