What kind of medicine does the beetle kill?

Scarabs can be killed by phoxim microcapsule, chlorpyrifos EC, kung fu EC, baode EC, fenvalerate, sukill EC and other pesticides. Generally, after being unearthed, 25% phoxim microcapsule or 50% phoxim EC or 40% chlorpyrifos EC can be used. The dosage per mu is 300~400g, diluted into 300 times solution, and evenly sprayed on the ground to kill. It can also be used during the adult attack period At dusk every night, the tree crown was sprayed with 2.5% kungfu emulsifiable concentrate 1800 times or 50% phoxim emulsion 1500~2000 times or 2.5% baode emulsifiable concentrate 2000 times or 20% fenvalerate 1500~2000 times or 40% sulfadiazine emulsifiable concentrate 1500 times.

In addition to medication, scarabs can also be controlled by the following methods:

1. Agricultural control

In winter and spring, plowing should be carried out between rows of fruit trees in combination with garden cleaning to eliminate many larvae; the farm manure applied should be fully decomposed to reduce the source of white grubs. Organic manure is not decomposed; herbicides are used a lot, the soil can not be deeply turned; orchards intercropped corn, peanuts and other crops. These reasons will provide a living environment for grubs and increase the outbreak of scarabs.

2. Artificial control

According to the characteristics of some species with suspended animation, in the evening under the tree tray spread a plastic sheet or placed a basin, swing branches, and then quickly shake the plastic sheet on the collection of scarabs, kill or feed chickens.

Suspended animation: When the beetle is affected or shocked, it will fall from the stop and assume suspended animation. After a while, you will recover normally.

3. Physical control

(1)Light trap: green beetle, black gill beetle, black velvet beetle, etc. have strong phototaxis, conditional orchards can be installed black light lamp or 60W bulb, trapping effect is significant. With black and green single-tube dual-light lamp, the scarab trap than the black light lamp can progress about 10%.

(2)Fruit vinegar liquid trap: use white star beetle love fruit vinegar liquid characteristics trap. The equipment method of fruit vinegar liquid is as follows: 1 part of fruit, 1 part of vinegar, 1.5~2 parts of sugar, 0.5 parts of water, chop the fruit, mix with vinegar, sugar and water, heat and cook into porridge, put it into a jar (half bottle is better), and then join half a bottle of dichlorvos liquid 500 times, mix evenly. During the peak period of white star beetle, one bottle of fruit vinegar was hung every 20~30m, and the height of hanging bottle was 1.2~1.5 m. The bottle should be close to the branches so that the adults can fly in. Eradicate the dead white star beetle every morning.

(3)Orchard cultivation sunflower trap: sunflower tea tray fragrance of white star chafer adult strong lure, in the orchard to individual loose cultivation method, 4~6 sunflower per mu. From June to August, the sunflower fragrance is used to lure, and a bag is used to cover the sunflower tea tray every morning to knock, so that the adults fall into the bag, and then concentrated killing. Each plant can trap more than 20 heads per day.

(4)Insect bait: the use of scarab adults with clustering characteristics trapped. In the orchard, hang 6~8 beer bottles evenly every 667㎡, hang the beer bottles on the branches about 1.5m high from the ground, catch 2~3 live white star beetle adults and put them into the beer bottles, which will attract other adults to fly into the bottles. Beer bottles can be filled with adults after 3~5 days.

(5)Poplar branch trap: use the characteristics of black gill beetle like to eat poplar and elm leaves, cut poplar branches or elm branches with leaves into 60cm segments, tie one end into a small handle with a thickness of 10cm, soak them in 50% phoxim or 90% trichlorfon 100 times solution for 2~3 hours, hang them on 1.5 m long sticks, and place them around orchards and between fruit trees at dusk. It has excellent pest control effect.

The above is a detailed introduction of the beetle pesticide kill and artificial control, physical control and artificial control introduced by the soil drift net editor. I hope it will help you.
