[Dichlorvos] Stones and kiwis are sensitive and disabled. Sorghum and rose are sensitive to dichlorvos and should not be used. Corn, beans, melon seedlings and willows are also sensitive, and the dilution should not be less than 800 times. Dichlorvos has obvious phytotoxicity to ornamental plants such as plum, cherry, peach, apricot, eucalyptus, 20th century pear, and Jingbai pear. Usually, other kinds of insecticides should be used instead. Dichlorvos also has different degrees of phytotoxicity to Rhododendron, Taro, kiwi, Chinese wolfberry, walnut and melon.
[Trichlorfon] Stone fruit, kiwifruit is very sensitive, disabled. Sorghum and beans are particularly sensitive and should not be used. Melon seedlings, corn, apples (dawn, marshals, etc.) are also susceptible to phytotoxicity in the early days. It has medicinal effects on cherry, plum, and apple varieties.
[Phosphos] Sorghum is not suitable for spraying. Corn can only be used to control corn mash. Cucumbers and kidney beans are sensitive to the drug. 50% emulsifiable concentrate is sprayed with 500 times of emulsifiable concentrate, and 1000 times of liquid may also have slight phytotoxicity. Beets are also sensitive to phoxim. For example, when mixing with boring, the dosage and suffocation time should be appropriately reduced. It is sensitive to leafy vegetables at high temperature and easy to burn leaves. The mechanism of chlorosis and other organophosphorus pesticides causing discoloration and other phytotoxicity is that the highly hydrophobic organophosphorus pesticide is adsorbed by the chloroplast or its surrounding tissues, causing the chloroplast function to be disordered, thereby hindering the electron conduction reaction, ie, the Hill reaction, inhibition. Photosynthetic, discoloration occurs, the more serious the phytotoxicity, the lower the carbohydrate content in the body and the relative increase in total nitrogen. 1 Do not mix with alkaline pesticides. 2 The drug is easy to decompose when it is light, and it is best to carry it in the evening when spraying in the field.
[Lego and Omethoate] Kiwi and ginseng are particularly sensitive to dimethoate and omethoate and are prohibited. Some varieties of hops, compositae, sorghum, tobacco, dates, peaches, pears, citrus, apricots, plums, olives, figs, etc. are sensitive to 40% dimethoate or omethoate emulsifiable concentrate diluted below 1500 times. If the peanuts are used too much, the cotyledons will not close at night, so pay attention to the concentration before use. For plum blossoms, cherry blossoms, flower peaches, eucalyptus leaves, stalked sea bream, apricots, pears and other Rosaceae ornamental plants, all of them can produce obvious phytotoxicity, and the damage to the stalks and coral flowers of Jujube is also great.
[Stone sulphur mixture] peach, plum, plum, pear, grape, beans, potato, tomato, onion, ginger, melon, cucumber, etc. For young plants of grape, peach, pear, plum, plum, apricot and other fruit trees, susceptibility to phytotoxicity should be taken.

It has certain phytotoxicity to kiwi, grape, cucumber and legume flowers.
[Borde liquid] Potato, tomato, pepper, melon, peach, plum, pear, apple, persimmon, cabbage, soybean, wheat, lettuce, etc., especially sensitive to copper ions, peach, apricot, plum, hawthorn are sensitive in the production season, Should be used with caution. When the lime in the Bordeaux mixture is lower than the multiple amount, the apple and the persimmon are susceptible to phytotoxicity, and the lime is used in multiples; when the lime is higher than the multiple, the grape is susceptible to phytotoxicity, and the lime is used in half amount. For other tree species, different formulas and ratios should be selected according to their characteristics. For apples that are sensitive to copper and resistant to lime, they can be used in lime or multi-type ratio; pears that are less sensitive to lime and copper can be used in the same amount of lime; sensitive to lime and resistant to copper. The grapes can be matched with a half-size of lime. When mixing with organic phosphorus, it should be used with caution. After spraying the stone sulfur mixture for 10 days, it can spray the Bordeaux mixture. After spraying the Bordeaux mixture, it takes 20-30 days to spray the stone sulfur mixture. 1 Avoid application on wet days or before the fog is dry to prevent phytotoxicity. Because of the strong permeability of copper sulfate, lime is drenched by rain or dew, and copper ions are left. The copper ions are very corrosive and easily cause damage to leaves and young fruits. Spray in the summer to avoid the hot sun at noon, so as not to cause high temperature damage caused by lime. Spray in the rainy season, increase the amount of lime as appropriate. 2 can not be mixed with alkaline agents, Bordeaux mixture with stone sulphur mixture, bacteriostatic, thiram, Fumei arsenic, etc., or alternate use interval is too short, are easy to produce phytotoxicity. 3 Bordeaux mixture should not be formulated in metal containers. 4 Bordeaux mixture is toxic to silkworms and should not be used on mulberry trees. 5 with the use. Bordeaux liquid preparation: First, pour the dilute copper sulfate into the thick lime milk and stir it while pouring; second, dilute the lime milk and copper sulfate while pouring into the agitated full bucket and pour it Stir it. The preparation method is simple and convenient, and the prepared Bordeaux mixture is slow to precipitate and has good protection effect after use.

[Amphetamine] In the high temperature and dry season of more than 28-30 degrees, streaky spots appear on the fruits of citrus.
[Fenthion] The seedlings, pears, peaches, cherries, sorghum and hops of cruciferous vegetables are sensitive to the drug and are prone to phytotoxicity and should not be used.
[P-Phosphorus and Methyl Parathion] Melons, especially seedlings, are sensitive to them and are not suitable for use.
[killing thiophene] sorghum, corn and cabbage, rapeseed, radish, broccoli, cabbage, green vegetables, cauliflower and other cruciferous materials sensitive to this drug, pay attention when used.

It can be mixed with avermectin, Bt, imidacloprid, dichlorfen, Wanling, can be killed, amber and copper sulphate. However, this product should not be mixed with sulphur-containing chemicals, Bordeaux mixture, dimethoate, ketone, carbaryl, chlorpyrifos, sterilized dan, chlorothalonil, and carbendazim pesticides. At the same time, it should be noted that the enemy can not be sprayed within 14 days after spraying the above-mentioned medicament on the fruit tree, otherwise phytotoxicity will occur. Use method First add a certain amount of water in the container, then add the specified amount of enemy insects into the water, and then add enough water. If mixed with other pesticides, mix other pesticides and water before pouring into enemy worms. Do not reverse them. In order to prevent the separation of the drug solution, it should be stirred constantly. In the summer, oil emulsions are used, and some tree species may cause phytotoxicity. They should be tested first.
