If you want to name one of the most cunning, most harmful to crops, and most difficult to control, it must be the ground tiger that bears the brunt of it.
Ground tigers, commonly known as silkworms and root-cutting insects, are the most common and most harmful underground pests that occur during the seedling stage of vegetables, cotton, corn and other crops.
It is said to be cunning, that is because it hides in the soil around the crop seedlings during the day, so that people cannot see, and then climbs out at night, endangering the roots of the crops and nibbling the seedlings at the waist;
It is said that it is harmful, because a ground tiger larvae can chew off 5 to 6 seedlings in a night, up to more than 10 trees, if the ground tiger spreads, there will be a lack of seedlings and ridges, and even overnight the phenomenon of all the seedlings being broken, resulting in huge losses;
The most difficult to control is because the ground tiger hides underground, and the traditional spraying method is not only laborious and laborious, but also difficult to kill, and the prevention and control effect is not ideal. So, what methods are most effective in controlling tigers?
Ground tigers are one of the main pests of dryland crops and are generally difficult to control due to their underground life. The use of chemical agents for prevention and control, the effect is not ideal, the cost is high. The use of castor leaves, seeds and the cultivation of castor beans can effectively control tigers.
Control of tigers in seedbed areas

Pick a portion of fresh castor leaves, and then add 10 times the water to cook together for 2 hours, after cooling, filter out the castor leaves to leave the sap, take a part of the juice and add 20 times the warm water to mix well, spray on the crop nursery bed, spray once in 5 days, generally spray 2 times to kill the tiger.

For small areas of vegetable fields or small amounts of fruit trees, tigers can be controlled by applying fertilizer and precise root application.
The old castor leaves are plucked from the shade (can not be exposed to the sun), and then crushed into a powder, when used, take a part of the castor leaf powder, mixed into 20 times the soil fertilizer, with the fertilizer into the soil, has a good effect on the prevention and control of tigers.
Peel, fry, mash, and then mix with 10 times the organic fertilizer and apply 1000 to 2000 grams per plant next to the roots of vegetable seedlings or fruit tree seedlings, killing all underground pests in the roots.

Castor plants and leaves contain a special substance, ricine, which can be quickly paralyzed, poisoned, and unable to reproduce when eaten by local tigers. Moreover, the castor stems and leaves have a peculiar smell, and some pests avoid it when they smell the peculiar smell of castor, so planting castor among the crops in the field has a special effect on the prevention and control of tigers.
The density of castor should not be too large among crops in the field, and 10 to 20 trees can be planted in every 667 square meters (1 mu) of land, and each tree is about 5 meters apart. The field where castor is planted can generally cure the tiger in that year.
