Comprehensive control method for dichocrocis punctiferalis in orchard for hylocereus undatus Foo-Lon

Abstract

The invention discloses a comprehensive control method for dichocrocis punctiferalis in an orchard for hylocereus undatus Foo-Lon. The control method involves physical control, chemical control and biological control to achieve control over dichocrocis punctiferalis in the orchard for hylocereus undatus Foo-Lon. According to the chemical control, after the orchard is cleaned in winter every year,firstly, an overwintering insecticide is scattered in the orchard, and then overwintering fertilizer is applied; in March-April every year, in combination with the application of spring fertilizer, apest-prevention agent is scattered in the orchard; from June every year, adult pests of dichocrocis punctiferalis enter an oviposition high-peak period and an egg incubation high-tide period, monitoring and forecasting are conducted in time, when the adult pests of dichocrocis punctiferalis are found, dichocrocis punctiferalis insecticide is continuously sprayed twice in time, the time interval ofthe two times of insecticide spraying is one week, and the insecticide is used up within 3-4 days every time. By means of the method, dichocrocis punctiferalis can be controlled, and the damage of dichocrocis punctiferalis is greatly reduced; moreover, a certain control effect is achieved on other diseases and pests, the incidence of the diseases and pests in the orchard is reduced, the yield andsingle-fruit weight of the dragon fruits can be increased, and the commercial fruit rate can be increased to 91% or above.

Description

technical field [0001] The invention belongs to the technical field of prevention and control of plant planting diseases and insect pests, and in particular relates to a method for comprehensive prevention and control of the peach borer in pitaya orchards. Background technique [0002] Dragon fruit (scientific name: Hylocereus undatus'Foo-Lon') is a tropical fruit with high nutritional value, which combines the advantages of fruit, flower buds, vegetables and medicine. Dragon fruit is sweet and flat, and its main nutrients are protein, dietary fiber, vitamin B2, vitamin B3, vitamin C, iron, phosphorus, calcium, magnesium, potassium, etc. Rich in a large amount of pulp fiber, rich in carotene, vitamins B1, B2, B3, B12, C, etc., the core (black sesame seeds) is also rich in calcium, phosphorus, iron and other minerals and various enzymes, Albumin, fiber and high concentration of natural pigment anthocyanins (especially in red meat), flowers, stems and buds have various effect...

AI Technical Summary

Problems solved by technology

[0004] Therefore, at present, more and more growers choose to plant pitaya, but due to inadequate cultivation and management of pitaya orchards, or inadequate management measures in high-temperature and high-humidity seasons, it is easy to cause outbreaks of diseases and insect pests in pitaya orchards, and the current status of people's prevention and control of plant diseases and insect pests is : 1. Not paying attention to the prevention of pests and diseases: fruit farmers do not pay attention to the prevention of pests and diseases in the production process, and cannot timely understand new pests and diseases. As a result, they cannot take timely treatment measures after the occurrence of pests and diseases. It is obvious to start processing, which will affect the yield and quality of dragon fruit

2. Prevention and control measures are too simple: in the process of dragon fruit planting, most fruit growers only rely on chemical pesticides to prevent and control pests and diseases, which will have an impact on the ecosystem inside the orchard, and long-term use of chemical pesticides will cause antibodies to the pests and diseases, and it is necessary to increase the amount of pesticides. volume or no effect

[0010] But, in the technical scheme disclosed above, can not be used for preventing and treating peach borer in pitaya, in the technical scheme disclosed above and other published documents, there is no control method about peach borer in pitaya, and pitaya is very easy to cause The outbreak of the peach borer, if effective control measures cannot be taken, once the peach borer breaks out in the dragon orchard, it will cause great losses to the dragon fruit growers
