Embodiment 1

[0018] Time: June 1st ~ June 25th, 2010.

[0019] Location: Jingting Mountain Tea Farm, Anhui Province.

[0020] Materials and Methods:

[0021] (1) The area of ​​the treatment area: a large organic tea garden was selected as the test tea garden, and 5 treatment areas were set up in the test organic tea garden, each with an area of ​​3 mu (each mu = 667 m 2 ), with an interval of 20 meters between treatment areas.

[0022] (2) Insect population survey method: Leafhopper with false eyes forms two population peaks every year. Before the first peak population comes, coordinate the implementation of pheromone color board trapping and tripterygium preparation control to reduce the leafhopper population peak . In each treatment area, the leafhopper population was investigated once every 4 days. When investigating insect populations, samples were taken at five points in each area, with an area of ​​tens of square meters per sample point, and the number of leafhopper adults and...

Embodiment 2

[0040] Time: September 8~October 2, 2010

[0041] Location: Jingting Mountain Tea Farm, Anhui Province

[0042] Materials and Methods:

[0043] (1) The area of ​​the treatment area: a large organic tea garden was selected as the test tea garden in the Jingting Mountain Tea Farm in Anhui Province, and five treatment areas were set up, each with an area of ​​3 mu (each mu = 667 m 2 ), with an interval of 20 meters between zones.

[0044] (2) Insect population survey method: Leafhopper with false eyes forms two population peaks every year. In this experiment, before the second population peak comes, the trapping of pheromone color boards and the control of tripterygium preparations are coordinated to suppress the leafhopper. Insect population peak. The insect population investigation method is the same as "Example 1".

[0045] (3) Setting of each treatment area: set a treatment method for each treatment area.

[0046] Treatment area 1—the application area of ​​Tripterygiu...

Embodiment 3

[0062] Time: May 31st ~ June 24th, 2011.

[0063] Location: Tea Garden of Zhejiang Gengxiang Organic Tea Industry Development Co., Ltd., Wuyi County, Zhejiang Province

[0064] Materials and Methods:

[0065] (1) Area of ​​treatment area: A large organic tea garden of Gengxiang Company was selected as the test tea garden, and five treatment areas were set up in the test tea garden, each with an area of ​​3 mu (1 mu = 667 m 2 ), with an interval of 20 meters between treatment areas.

[0066] (2) Insect population investigation method: Before the first population peak of Leafhopper with false eyes comes, the trapping of pheromone color board and the control of Tripterygium wilfordii preparation are coordinated and implemented, and the insect population investigation method is the same as "Example 1".

[0067] (3) Setting of each treatment area: set a treatment method for each treatment area, and the test materials and their usage methods are the same as above.

Abstract

The invention provides a coordinated non-pesticide method for preventing and controlling Empoasca vitis Gothe in organic tea garden. (E)-2-hexenal, (Z)-3-hexen-1-ol and linalool constitute a trap agent, which is loaded on a rubber head of a trap to make into a trap core. A viscous color plate is made by adopting bud green color and jasmine yellow color. A Radix Tripterygii Wilfordii preparation is prepared from Radix Tripterygii Wilfordii alkaloids 0.1-10 wt%, nicotine 0.1-20 wt%, filler or solvent 1-99 wt%, dispersant and emulsifier 1-20 wt%. In 5-10 days before inflexion point, the pheromone color plate trap is used for trapping adult insects; and in 1-3 days, the Radix Tripterygii Wilfordii preparation is applied for effectively lowering Empoasca vitis Gothe density in tea garden. The inventive method can effectively control Empoasca vitis Gothe population in organic tea garden, promote domestic organic tea industry, and reduce or eliminate application of pesticides in tea garden.

Description

technical field [0001] The invention belongs to a tea tree pest control method, and relates to a method for coordinating the use of pheromone color plate traps and tripterygium preparations to prevent and control the most difficult pest in organic tea gardens, the green leafhopper with false eyes, which can avoid the application of chemical pesticides. Background technique [0002] At present, the area of ​​organic tea gardens in my country has reached nearly 40,000 hectares, in which the use of chemical fertilizers and chemical pesticides is prohibited. But the false-eyed green leafhopper Empoasca vitis G?the is widely distributed in the tea area of ​​mainland China. Its adults and nymphs suck the juice of tea shoots, and the female adults lay eggs in the tea shoots and destroy the transport tissue. From the Rizhao tea area of ​​Shandong Province in the northernmost tea area to the Sanya tea area of ​​Hainan Province in the southernmost tea area, there are 7 to 22 generat...
