When it comes to harvesting peanuts every year, when plucking peanuts, there is always a particularly annoying bug. This insect is white and fat, and it not only eats peanuts, but also eats the roots of other crops, causing crop yields to decrease. Is there any way to completely solve this kind of bug that gives farmers a headache?
How to control this bug? Farmers have had a response many years ago. In our case, there is a farming custom called "fried silkworms" during the spring equinox. Beans, wheat and the like are fried in a pot, and when frying, there are still "mantras" that need to be chanted: "Stir-fry the soil silkworm, fry the soil silkworm, fry the soil silkworm without the soil silkworm"!
I think this is the most traditional and ancient way to manage these silkworms and tigers. But whether this habit has an effect or not, everyone knows it. The best way to really solve this bug is only to use pesticide treatment.
Ground tigers, also known as root-cutting insects and night bugs, are one of the main pests of crops. It can harm many crops, including cotton, corn, vegetables and even fruit trees. When the larvae it eats the roots, and the elderly larvae, it will bite off the crops near the surface, resulting in a lack of seedlings, and even destroy the seeds in severe cases, and need to be re-sown.
Many farmers find it difficult to control tigers. Because the earth tiger is always lurking underground, it seems that there is no particularly effective way to deal with it. In fact, the management of tigers can also have a very effective solution, how to govern, more need to be adapted to local conditions.
For the prevention and control of ground tigers, it is necessary to treat underground pests on the ground, adult larvae combined treatment, and field and field selection in and out of the field, in order to effectively solve the harm of ground tigers. The selection of agents for tigers should be based on pyrethroid insecticides and organophosphate insecticides.
The first is the treatment of seeds, the use of medicinal seeds before sowing, the use of chemical seeds before sowing, the use of 50% octylthion emulsion, 10% pyrethroid emulsion or cypermethrin emulsion and other seeds are good. Sowing after 3-5 hours of suffocation can effectively control tigers.
There is also the treatment of arable land. Ploughing the cultivated land can effectively kill the larvae and eggs of the land tiger in the soil. In addition, the weeds on the edge of the field are also the main hosts of insect eggs and food for larvae, and cleaning up weeds can also effectively control insect pests.
And how to control the ground tiger in the later stage?
It can be mixed in a 1:50 ratio using 50% octyl thiophosphate emulsion and fine sand soil, and spread in the field along the roots of the plant. Since the larvae of the ground tiger are mainly active at night, the effect of spraying poisonous soil is best in the evening.
Of course, pesticides can also be used for insecticide. Killing tigers with enemies can also be effective in controlling the ground, and spraying them in the evening using the dilution of enemy killings. When night falls, the temperature drops, the amount of evaporation decreases, and the soil and plants are moist, which can effectively maintain the medicinal effect. When the local tiger larvae come out to harm the plant, they happen to meet the drug, and the effect can be effective. Three consecutive days of medication can basically guarantee the killing of 100% of the tigers!
The larvae of the ground tiger are most sensitive to pyrethroid, while the resistance to carbamate is stronger. Killing the tiger is more effective by using the drugs of fat earth dragon, ground bully, and fat ground tiger!
