Lettuce is a one-year or two-year-old vegetable of the Asteraceae family and is cultivated mainly in spring and autumn. Lettuce is a crop that is more sensitive to herbicides (easier to produce phytotoxicity), because its roots are shallow, herbicides can easily penetrate into the root layer, and commonly used herbicides have a certain degree of impact on the growth of lettuce. For weeds growing year-round and weeds are more serious, chemical weeding is very particular about it.

Herbicides available

Fifty-two percent trifluralin was sprayed with 100-125 ml of 48% trifluralin before and after lettuce was transplanted, and lightly mixed with soil.

25% herbicidal ether Spraying the soil with 25% of herbicide ether emulsifiable concentrate 400-500 ml/mu before emergence of lettuce after sowing, the application effect after emergence is poor and phytotoxicity is easy to produce. The effect of spraying and weeding is good under the conditions of flat land and moist soil. The spraying should be carried out under clear and windless conditions without destroying the soil layer.

After transplanting 24% Guoer with lettuce, 40-48 ml of 24% Goer EC was added to 60 liters of water, and the surface was evenly sprayed. Do not turn the soil after application and keep the surface moist. Note that lettuce must not be sprayed. Mulching mulching lettuce, seedlings per acre with 24% of Gore EC spray 30 ml.

90% high-effective herbicide can be applied on live lettuce, and can be sprayed with 90% high-effective herbicidal granules (110-150 ml) plus 60 liters of water per acre before or after transplanting. Do not turn the soil after application to keep the surface moist. Mulching seedling lettuce, seedbeds with 90% efficient kill herbicide 80 ml spraying. The herbicide is safe for post-crop crops.

Precautions

Lettuce, celery, and boiled vegetables are more sensitive to Napropamide and we should not use Napropamide for weeding. Trifluralin cannot be administered when lettuce is sown.

Long-acting herbicides such as chlorosulfonylurea, metsulfuron-methyl, tosulfuron-methyl, ethamesulfuron-methyl, bensulfuron-methyl, chlorsulfuron-methyl and pyridinium iodine Long, tribenuron, ether methyl, chlorimuron, and so on.

Can not be used in the killing of herbicides field lettuce lettuce, because the fast killing of earthworms in the soil remains too long. Quick killings are mainly used for rice. It is best not to use vegetables. According to reports, no crops can be planted except for rice within 309 days after the application of the fast killing plant; eggplant and tobacco cannot be planted within one year; tomato and carrots cannot be grown within two years (Umbrella crops such as carrots, celery, parsley, etc. are not suitable for killing sensitive). It should be noted that when spraying fast killings, do not cause drift, and do not use water that has been killed quickly to irrigate the vegetables.

Smart Home

Smart home allows users to manage home devices by more convenient means, such as touch screen, hand-held remote control, telephone, Internet to control home devices, more can perform situational operations, so that multiple devices form a linkage; on the other hand, the various devices in the smart home can communicate with each other without user command and can interact according to different states, thus bringing maximum convenience, efficiency, safety and comfort to users. The so-called smart home era is the Internet of things into the family era.
