The utility model relates to the technical field of root irrigation devices, in particular to an insect pest prevention liquid medicine root irrigation device for tobacco planting, which comprises a base, a vertical rod, a detachable battery mechanism, a root irrigation cylinder, a root irrigation mechanism and a conveying mechanism. A vertical rod convenient to move is arranged at the rear end of the surface of the base, a detachable battery pack mechanism used for supplying power to the device is arranged at the front end of the vertical rod, a positioning groove is formed in the center of the front end of the surface of the base, a root irrigation cylinder used for containing root irrigation liquid medicine is arranged above the positioning groove, and root irrigation mechanisms used for irrigating roots of tobacco leaves are arranged on the two sides of the root irrigation cylinder. A conveying mechanism used for conveying root irrigation liquid medicine is arranged between the root irrigation mechanism and the root irrigation cylinder. According to the utility model, the root irrigation mechanism is matched with the conveying mechanism, and the position of the hole pressing table can be flexibly adjusted according to the planting distance and growth state of tobacco leaves, so that the root irrigation requirements under different planting conditions are met, and the problems that the root irrigation structure of the traditional root irrigation device is fixed in distance and insufficient in flexibility are effectively solved.

The invention relates to an insect-resistant agent and a prevention and control method for plant pests, and relates to the technical field of plant insect-resistant agents. Wherein the insect-resistant agent comprises a semen cuscutae extract; the preparation method of the semen cuscutae extract comprises the following steps: carrying out first extraction treatment on dried semen cuscutae powder by adopting a first solvent, and removing an extracting solution to obtain powder subjected to the first extraction treatment; the first solvent is an aliphatic alkane solvent; carrying out second extraction treatment on the powder subjected to the first extraction treatment by adopting a second solvent, and removing an extracting solution to obtain powder subjected to the second extraction treatment; the second solvent is an ester organic solvent; performing third extraction treatment on the powder subjected to the second extraction treatment by adopting a third solvent, and collecting a third solvent extracting solution; the third solvent is one or more of ethanol, methanol and water; and performing solvent removal treatment on the third solvent extracting solution to obtain the semen cuscutae extract. The invention mainly develops an insect-resistant agent which is green, efficient, low in toxicity and not easy to generate drug resistance.

The present application relates to the technical field of insecticide, and discloses a plant insecticide and a preparation method thereof, which comprises the following components by weight: 1-2 parts of pyridine insecticide, 0.8-1 parts of carvacrol, 3-5 parts of modified starch and 3-4.5 parts of sodium alginate. The pyridine insecticide and the carvacrol are compounded, and the two play a synergistic effect, which significantly improves the toxic activity on agricultural pests, and the insecticidal efficiency is effectively improved compared with the single use of the pyridine insecticide or the carvacrol. The carvacrol in the plant insecticide is derived from plant extraction, and has the characteristics of easy degradation and low toxicity; the modified starch and the sodium alginate are both natural polymer materials, can be biodegraded, and will not cause pollution to the soil and water, which meets the development demand of green agriculture.

The invention relates to the technical field of insecticides, and discloses a botanical insecticide and a preparation method thereof, the botanical insecticide comprises the following components by weight: 1-2 parts of a pyridine insecticide, 0.8-1 part of carvacrol, 3-5 parts of modified starch, and 3-4.5 parts of sodium alginate.
