Spodoptera litura, winter melon is very harmful, what medicine is good to use?

Spodoptera litura, which was sprayed alternately with 21% killing emulsifiable concentrate 6 000 8 000 times. Winter melon is a common vegetable in life, and we eat it is also very delicious, some people just like some winter melons very much, and another is when we make soup, or stew some pork rib soup, add a few winter melons, it will be very delicious, and therefore, in the process of winter melon planting, it is inevitable that there will be some pests and diseases, among them, if Spodoptera litura, it is more common one, <>

This ** is very harmful on the winter melon, it is an omnivorous, or a gluttonous pest, my country is very widely distributed, mainly our country is mainly divided into the north and south, the north is good to say, as long as there are more in the south, and in addition to these winter melons, he will also erode other vegetables, it can be said that it is very annoying, and then his shape is, a small round brown thing, as long as they will cause some bad effects on plants or vegetables, the effect of some smoke of plants and vegetables. <>

And then we humans can't get or can't absorb some of the nutrients that we deserve, so it's not good to say this. Therefore, if there are vegetables with such problems, there are three main methods, the first is mainly about agriculture, to properly and weeds, and combined with some operations in the field to remove such pests, the second is to trap, can be with other vegetables, or specifically to fight against its natural enemies, can also reduce their number, the third is some aspects of chemistry, you can buy some about specialized, ** these pests, Those drugs are mixed with some appropriate water, and then sprayed on plants or vegetables, so that when pests bite it, they will get a certain amount of control and effective control, so this is also very necessary. <>

1. Booby trap adult insects. Adult peak point (black light) lamp or set up sweet and sour liquid tray (sugar: sprinkle:

Vinegar: water = 2 1 2 2) add a small amount of pesticide to trap moths, or insert dipping medicine willow branches to trap moths. 2. Pharmaceutical prevention and control.

For pesticide control at the peak of larval incubation, you can use 50% fenvalerate 4000 times, or 20% fenvalerate 2000 times, or 5000 times kung fu solution, 1000 times of larvaluride, or 21% 6000-8000 times of killing, or 50% phosphine or 80% dichlorvos 1000-1500 times of liquid, 2-3 times, 1 time every other day, alternate spraying. Commonly used drugs fenvalerate, fenvalerate, fenamethrin, fengiving, chlorpyramide, pyroxine, dichlorvos.

Avermectin, cypermethrin, and phosphine can be used. These drugs are very effective and can have a certain preventive effect.

It will work well with insecticides that are specifically designed to deal with them, because they are very harmful insects, and pesticides have been developed to prevent them.

Virulence should be used, the effect of this medicine is very good, and it can harm pests and diseases, which is 5 times the efficacy of ordinary medicine, which is very effective.

Spodoptera liturae can be sprayed alternately with 6 000 8 000 times of 21% killer EC, or 4 000 6 000 times of 50% fenvalerate EC, or 2 000 3 000 times of 20% cyanoma or chrysanthemum EC, or 4 000 5 000 times of Kung Fu and Uranus EC.

Spodoptera liturae can also be used with 20% emulsifiable concentrate 3000 times, or 80% dichlorvos, or chlorpyramide, or 25% malathion 1 000 times, or 5% carctogram, or 5% Nongmonte 2 000 3 000 times liquid, 2 3 times, every 7 10 days 1 time, spray evenly and spray the feet.

Spodoptera litura, with emamectin benzoate, indoxacarb, carcar, flubenziliprole, cyantraniliprole, azorpaniliprole, chlorfenapyr, chlorfenoxonil, butylurea, methoxyfenozide, ethylspinosad, cyanidi, Spodoptera liturali (Spodoptera exigua, Spodoptera exigua) karyopolyhedrovirus, Bacillus breve and other pesticides. Spodoptera litura, with emamectin benzoate, indoxacarb, carcar, flubenziliprole, cyantraniliprole, azorpaniliprole, chlorfenapyr, chlorfenoxonil, butylurea, methoxyfenozide, ethylspinosad, cyanidi, Spodoptera liturali (Spodoptera exigua, Spodoptera exigua) karyopolyhedrovirus, Bacillus breve and other pesticides.

With the development of science and technology and the improvement of living standards, farmers no longer rely on the weather for food, and when planting crops, they also know that spraying pesticides and fertilizing can help them increase their yields, which is becoming more and more advanced. There are different pesticides for different insects, so what medicine does Spodoptera litura?

Spodoptera liturae is a harmful insect that especially likes to eat the flowers, leaves, and fruits of crops. For the hard-working farmer uncle, they hate them to the core, experienced farmers know that to deal with the pest of Spodoptera litura, you must use a specific configuration of pesticides to be effective, general pesticides do not work on the antibodies in the body of Spodoptera litura, you must configure a specific pesticide to work. For example, the heavy borer of rice, or the emamectin benzoate suspension plus organosilicon penetrant is fused and sprayed in time at the larval stage of Spodoptera litura, so that it will die and no longer reproduce.

Therefore, the drug for Spodoptera liturae must be a specific pesticide configuration. For example, emamectin salt suspension plus organosilicon penetrant, or heavy ** heavy borer of rice.

Spodoptera litura's general medication must be a pesticide of a specific configuration. For example, emamectin benzoate suspension, plus organosilicon penetrant, or heavy heavy borer of rice, so that it can kill Spodoptera litura.

Summary. Hello, I am glad to answer for you that Spodoptera litura is seriously resistant, please ask emamectin benzoate for pesticides to fight Spodoptera litura, with emamectin salt, indoxacarb, carcarb, flubenziliprole, cyantraniliprole, azolfeniliprole, chlorfeniril, chlorfenoxonil, butylurea, methoxyfenozide, ethyl spinosa, cyanopromizone, Spodoptera litura (alfalfa Spodoptera exigua, Spodoptera exigua) karyopolyhedrovirus, Bacillus breve and other pesticides.

Spodoptera liturae is seriously resistant, what is there for pesticides?

Hello, I am glad to answer for you that Spodoptera litura is seriously resistant, please ask if there is a pesticide to fight Spodoptera litura, with emamectin salt, indoxacarb, carcarb, flubenzanamide, cyantranidin, azolfeniliprole, chlorfenapyr, chloroxanonil, butyl etherurea, methoxyfenozide, ethylspinosad, cyanopromita, Spodoptera litura, Spodoptera liturali (Spodoptera exigua, Spodoptera exigua) karyopolyhedrovirus, Bacillus breve and other pesticides.

What is the reason why the pepper leaves are rolled up.

Drought. The symptoms of leaf rolling caused by drought are the longitudinal rolling of pepper leaves, and the leaves appear to be thickened, brittle or hardened to varying degrees. If it is due to the soil or the air is relatively dry, Zheng Zhen leads.

Control measures: In summer, the weather is hot, and the water evaporation of Luling* soil is large, resulting in the inability to absorb nutrients in the pepper production process, and the leaves will roll up. To water properly, take as much water as possible to water frequently, and observe the growth of the leaves after watering.

Deficiency. In the process of pepper cultivation, if some trace elements are missing, leaf curling will also occur.

Spodoptera liturae can be sprayed alternately with 6 000 8 000 times of 21% killer EC, or 4 000 6 000 times of 50% fenvalerate EC, or 2 000 3 000 times of 20% cyanoma or chrysanthemum EC, or 4 000 5 000 times of Kung Fu and Uranus EC.

Spodoptera liturae can also be used with 20% emulsifiable concentrate 3000 times, or 80% dichlorvos, or chlorpyramide, or 25% malathion 1 000 times, or 5% carctogram, or 5% Nongmonte 2 000 3 000 times liquid, 2 3 times, every 7 10 days 1 time, spray evenly and spray the feet.

<>Spodoptera exigua can be sprayed with contact pesticides, such as cypermethrin, kung fu ethrin, trichlorfon, chlorpyrifos EC, acemethamidophos EC, etc. Precautions: The effect of medication is better in the initial hatching larval stage, and the efficacy will be reduced after entering the older larval stage; The amount of liquid medicine should be sufficient, and it must be sprayed evenly and thoroughly when spraying.
