Plant immune resistance inducer for preventing and controlling arecanut yellow leaf disease and use method of plant immune resistance inducer

Abstract

The invention discloses a plant immune resistance inducer for preventing and controlling arecanut yellow leaf disease and a use method of the plant immune resistance inducer. The plant immune resistance inducer comprises the following effective components: oxyenadenine, fucoidin, humic acid, cyantraniliprole, pyriproxyfen, a penetrant T and a surfactant, namely dodecyl betaine, wherein the fucoidin can be extracted from brown algae such as kelp, nemacystus, ascophyllum nodosum, undaria pinnatifida, sargassum fusiforme, sargassum, chorda filum and fucus vesiculosus. After the plant immune resistance inducer is diluted by 1500-2000 times, foliage spraying is performed at an early stage of arecanut yellow leaf disease; and the plant immune resistance inducer can also be sprayed in a low-concentration and small-amount manner when areca plants are not infected with the arecanut yellow leaf disease so as to realize defense. The plant immune resistance inducer aims at stimulating the immunity of plants, indirectly prevents and controls arecanut yellow leaf disease, does not enable pathogenic bacteria to generate drug resistance, is low in human and animal toxicity, good in environmental compatibility and suitable for large-scale popularization and application, controls the deterioration of the disease condition on the basis that no effective medicament is available for curing arecanut yellow leaf disease at present, and ensures the sustainable development of the betel nut industry.

Description

technical field [0001] The invention relates to the technical field of biological pesticides for betel nut diseases and insect pests, in particular to a plant immune inducer for preventing and controlling betel nut yellowing disease and a use method thereof. Background technique [0002] Betel nut (Areca catechu L.) is a perennial evergreen tree of the palm family (Arecaceae). The peel, buds and flowers of betel nut can be used as medicine, which has the effects of antibacterial, invigorating the stomach, and exciting skeletal muscles. Like other palm plants, areca nuts are susceptible to various diseases in different growth and development stages, among which areca nut yellowing is the most important disease of betel nuts in Hainan, and has become a key factor restricting the sustainable development of betel nut industry. Studies have shown that betel nut yellowing disease can be caused by virus (Arecapalmvelarivirus 1, APV1) and phytoplasma (Arecanut yellow leaf phytoplas...

AI Technical Summary

Problems solved by technology

[0005] In view of the advantages of the above-mentioned plant immune anti-attractant and the current situation that there is no effective drug to cure the yellowing disease of betel nut, the present invention proposes a plant immune inducer for preventing and controlling the yellowing disease of betel nut, which is used to improve the current yellowing disease of betel nut. situation
