A method for green prevention and control of banana flower thrips in banana orchards

Abstract

The invention provides an environmentally friendly method for preventing and controlling banana flower thrip for a banana garden and belongs to the field of prevention and control of fruit tree diseases and insect pests. According to the method, prevention and control measures such as variety selection, host plant isolation, broken bud bagging, garden clearing and bud protection, healthy cultivation, physical and chemical luring and control, biological prevention and control and emergency medicine application are selectively integrated targeted to four banana growth periods including the early stage of bud emergence, the bud emergence and young fruit period, the fruit swelling period, the later period of harvesting and the like, the cooperative disease and insect pest control function of the measures is fully played, the measures are combined to form an environmentally friendly preventing and controlling method for banana flower thrip in all growth periods of bananas, and an environmentally friendly sustainable control technology mode for preventing and controlling harms of banana flower thrip from the source is constructed. By means of the environmentally friendly method, occurrence of banana flower thrip in the banana garden can be effectively controlled, harms of the flower thrip are controlled within the economic threshold range, utilization of chemical pesticide in the banana garden is extremely remarkably reduced, and great significance in environmentally friendly production of bananas and environmental protection is achieved.

Description

technical field [0001] The invention relates to a method for green prevention and control of banana flower thrips in banana orchards, and belongs to the field of prevention and control of fruit tree diseases and insect pests. Background technique [0002] banana Musa nana Lour. It is a monocotyledonous herbaceous plant belonging to the Musaceae Musaceae Musa genus Musa. It is one of the main fruits grown in the hot areas of Fujian. The main species is the 'Williams' banana. M. AAA Group Giant CavendishWilliams, Red Banana M. AAA Group Red green and powdered banana M. AAB Group Fenjiao and others. According to statistics, in 2014, the output of Fujian Province was about 9.17×10 8 kg, ranking second in the province's fruit output, is the main source of income for farmers in hot areas. [0003] The growth process of bananas needs to go through four periods: the early budding period, the budding and young fruit period, the fruit expansion period, and the post-harves...

Problems solved by technology

In recent years, thrips banana flower Thrips hamaiiensis The occurrence of (Morgan) has become more and more serious, and has become one of the main pests on bananas in our province; this insect damages the fresh and tender parts of the ovary of banana flower buds, sex flowers and outer bracts and banana young fruit epidermis. Adults also lay eggs in the banana flower bud ovary and young fruit epidermis, causing the proliferation of tissue cells in the damaged part. Water-soaked spots appear at the beginning, and then gradually turn into red or reddish-brown spots. The tissues gradually become corky and turn into dark brown or black small bumps, which directly or indirectly affect the yield and quality of bananas, and reduce the income of fruit growers.

[0004] Due to the small size of Banana flower thrips, strong fecundity and concealment, and easy outbreaks, the current prevention and control measures focus on the use of chemical pesticides with systemic and osmotic effects. Labor costs are also likely to cause "3R" and pesticide damage problems, pollute the environment and endanger human health, and do not comply with my country's agricultural "two reductions" policy (reduce the use of chemical fertilizers and pesticides, and achieve zero growth in the use of chemical fertilizers and pesticides), urgently need to assemble suitable Based on the green prevention and control methods of Banana Flower Thrips in each growth period, a green and sustainable control technology model is constructed to prevent and control Banana Flower Thrips from the source, so as to prevent and control the occurrence and harm of Banana Flower Thrips more efficiently and safely. Maintain high quality and economic value of bananas
