Description

Technical Field

[0001] The present invention relates to the technical field of agriculture, and in particular to a method for controlling pests of Lipu taro and a spraying device. Background Art

[0002] Blight is a common and serious disease of Lipu taro. It primarily affects leaves, petioles, and bulbs. On leaves, yellowish-brown, water-soaked spots appear in the early stages of the disease, then rapidly expand to become circular or irregular in shape. The edges of the spots are unclear, and there's a layer of white mold. In severe cases, multiple spots can fuse together, causing the leaves to rot and wither. When petioles become infected, long, dark brown spots appear, which break easily, affecting the plant's nutrient transport and support functions. When bulbs become infected, brown spots first appear on the surface, then expand inward, causing the entire bulb to rot and resulting in severe yield losses. Furthermore, blight is prone to recurrence, so it's necessary to address these issues. Summary of the Invention

[0046] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0047] like Figure 1 As shown, a method for controlling pests of Lipu taro comprises the following steps:

[0048] Pre-planting preparation: Plough the planting site for the first time and expose the soil to sunlight for 15-20 days. Plough the site a second time, applying fully decomposed farmyard manure and wood ash during the second plowing process to allow the manure and wood ash to mix with the soil. Dig trenches around the edges of the planting site, construct water storage tanks surrounding the site, and disinfect the water entering the water storage tanks.

[0049] Disinfection of seed taro: Before sowing, use metalaxyl or carbendazim to prepare a solution in a set ratio, soak the seed taro for 15-30 minutes, disinfect and sterilize, then dry it before sowing;

[0050] Spraying: During the taro growth period, if the early symptoms of the disease are found, use dimethomorph, cymoxanil, or fluopyram and propamocarb to prepare a solution in a set ratio. Use a sprayer to spray the taro every 7-10 days for 2-3 consecutive times.

[0051] Root irrigation control: Use carbendazim or metalaxyl mancozeb for root irrigation treatment, with a dosage of 200-300 ml per plant.

[0052] In the specific application of this embodiment, the taro planting field is plowed twice and the soil is exposed to the sun for 15-20 days. The ultraviolet rays in the sun kill some pathogens, insect eggs and other harmful organisms, improve the physical and biological properties of the soil, and reduce the incidence of diseases.

[0053] Disinfecting the water in the water tank and then introducing the water in the water tank into the planting site to irrigate the taro can prevent pathogens, insect eggs and other harmful organisms in the water from entering the planting site; the water tank is also convenient for adjusting the humidity of the planting site. When there is too much water in the planting site, the accumulated water in the planting site can be introduced into the water tank. When the planting site is short of water, the water in the water tank can be pumped to the planting site; by adjusting the humidity of the planting site, high temperature and high humidity can be avoided, and the occurrence of epidemics can be reduced.

[0054] Metalaxyl exerts its bactericidal effect by inhibiting the growth of pathogen mycelium and the germination of spores. It has a very good preventive and therapeutic effect on diseases caused by Oomycetes and blight. It can specifically interfere with the physiological and biochemical processes of pathogens, hindering the invasion and spread of diseases. Carbendazim interferes with the mitosis process of pathogen cells, inhibits the formation of their cell nuclei, and then destroys the normal growth and reproduction of pathogen cells to achieve the purpose of bactericidal. It has a preventive and therapeutic effect on many fungal diseases, and can also have a certain inhibitory and disinfecting effect on some pathogens of blight. By preparing a liquid medicine with metalaxyl or carbendazim and soaking the seed taro in it, the seed taro can be effectively disinfected and sterilized.

[0055] The targets of dimethomorph are some key enzymes and physiological processes related to the cell wall synthesis and cell membrane function of pathogens. By inhibiting these key links, it hinders the growth of pathogen hyphae, spore germination and zoospore motility, thereby effectively preventing the infection and spread of blight pathogens to plants. Cymoxanil inhibits some enzyme systems involved in energy metabolism and biosynthesis in the pathogen's body, thereby affecting the metabolism of the pathogen, inhibiting the growth, reproduction and other physiological activities of the pathogen, preventing it from normally infecting plant tissues, and has a good prevention and control effect on Oomycete diseases such as blight. Fluopyram has good systemic conductivity and can be quickly absorbed by plants and transmitted in the body. Cymoxanil has a destructive effect on the cell membrane of pathogens. After the two are combined, the synergistic effect is obvious. On the one hand, fluopyram can help the agent better transmit to the diseased site in the plant body. On the other hand, Cymoxanil inhibits the pathogen at the cell membrane level, interfering with the growth, reproduction and infection process of the blight pathogen from multiple angles, and has a more outstanding prevention and control effect on blight.

[0056] After being absorbed by the plant roots, carbendazim is conducted in the plant body and acts on the cells of the pathogen, affecting its cell division and the function of the cell membrane, thereby inhibiting the growth and reproduction of the pathogen; it can play a good prevention and control role in some diseases that can be transmitted through the soil or infect the roots; metalaxyl mancozeb is a fungicide compounded by metalaxyl and mancozeb. Metalaxyl mainly inhibits the growth of pathogen mycelium and the germination of spores, while mancozeb can form a protective film on the surface of the plant, preventing and controlling diseases through a multi-target mechanism of action; after the two are compounded, they have the dual effects of systemic treatment and protection, and have a good prevention and control effect on diseases such as blight caused by Oomycetes. They can not only prevent pathogens from infecting plants, but also inhibit the further development of the disease after the plant is infected.

[0057] This embodiment arranges a water storage tank, which not only facilitates the adjustment of the humidity of the planting site, but also prevents the introduction of pathogens, insect eggs and other harmful organisms from the outside; it also carries out targeted disease prevention and control according to the growth cycle of taro, prevents the recurrence of diseases, and improves the prevention and control effect of diseases.

[0058] The above embodiment further includes the following steps:

[0059] The water tank is fed with external water flow to control the water level in the water tank to be lower than the upper end surface of the planting site. Each time a new water flow is fed into the water tank, the water in the water tank is disinfected. The disinfected water is then fed into the planting site to irrigate the taro.

[0060] Water tanks are also used to clean and disinfect people and agricultural tools entering the planting areas.

[0061] In the specific application of this embodiment, before watering the water tank, the water in the water tank is disinfected to disinfect and sterilize pathogens, insect eggs and other harmful organisms in the water to prevent pathogens, insect eggs and other harmful organisms from entering the planting area; the disinfected water in the water tank is used to clean and disinfect people's feet and agricultural tools, which can further reduce pathogens, insect eggs and other harmful organisms from entering the planting area and avoid damage to taro.

[0062] The above embodiment further includes the following steps:

[0063] During the growth period of taro, Bacillus or Trichoderma biological agents are regularly prepared into a liquid according to a set ratio, and the liquid is sprayed on the taro every 15-20 days through a spraying equipment.

[0064] In the specific application of this embodiment, the liquid medicine is sprayed onto the soil and the leaves of taro through the spraying equipment, and the growth and reproduction of taro blight pathogens are inhibited by the beneficial microorganisms of Bacillus and Trichoderma, thereby achieving the purpose of preventing and controlling the disease.
