Embodiment 1

[0021] Insect source for the test: the larvae of Spodoptera spp. collected in the field in July 2010, artificially reared indoors, obtained adults and reared the eggs to the age required for the test.

[0022] The test method is as follows:

[0023] Determination method of contact toxicity: The contact toxicity was determined by dipping method. Take the 2nd and 4th instar larvae of Spodoptera exigua with consistent growth, soak them in the treatment solution for 3 seconds, put them on absorbent paper to absorb the excess solution, and then put them into a 12-well plate with normal amaranth leaves. 30 larvae were repeated 3 times, and water treatment was used as a control. Each treatment was placed in a 26°C incubator for normal feeding, and the number of dead insects was counted after 24 hours. Adults of Spodoptera spp. were measured by spraying, 30 adults per treatment, repeated 3 times, and water treatment was used as a control.

Embodiment 3

[0048] Test site: Zangcun, Ningjin County, Xingtai.

[0049] Variety: The tested variety of summer maize is Zhengdan 958.

[0050] Test time: July 5, 2011.

[0051] The soil of the test plot was loamy with medium fertility.

[0052] Test method: Use 5Kg of fragrant wheat bran for each mu, mix with appropriate amount of water until moist, add various treatment chemicals, mix well, and sprinkle on the side of corn seedlings along the ridge in the evening. The specific treatment is as follows:

[0053] A: Mu use 15mL15% indoxacarb suspending agent;

[0054] B: Mu use 12mL15% indoxacarb suspending agent + 40mL80% dichlorvos emulsifiable concentrate (active ingredient weight ratio 1:17.78);

[0055] C: Mu use 9mL15% indoxacarb suspending agent + 80mL80% dichlorvos emulsifiable concentrate (active ingredient weight ratio 1:47.41);

[0056] D: Mu use 6mL15% indoxacarb suspending agent + 120mL80% dichlorvos emulsifiable concentrate (active ingredient weight ratio 1:106.67);

[0067] Test site: Zangcun, Ningjin County, Xingtai.

[0068] Variety: The tested variety of summer maize is Zhengdan 958.

[0069] Test time: July 5, 2011.

[0070] The soil of the test plot was loamy with medium fertility.

[0071] Test method: Use 5Kg of fragrant wheat bran for each mu, mix with appropriate amount of water until moist, add various treatment chemicals, mix well, and sprinkle on the side of corn seedlings along the ridge in the evening. The specific treatment is as follows:

[0072] A: Mu use 15mL15% indoxacarb suspending agent;

[0073] B: Mu use 12mL15% indoxacarb suspending agent + 60g90% crystal trichlorfon (active ingredient weight ratio 1:30);

[0074] C: Mu use 9mL15% indoxacarb suspending agent + 120g90% crystal trichlorfon (active ingredient weight ratio 1: 80);

[0075] D: Mu use 6mL15% indoxacarb suspending agent + 180g90% crystal trichlorfon (active ingredient weight ratio 1:180);

Abstract

The invention relates to prevention and treatment of agricultural pests, in particular to a new use of indoxacarb utilized for preventing and treating athetis lepigone. The new use has the beneficial effects that as the indoxacarb is utilized for preventing and treating the athetis lepigone, the use amount of the indoxacarb is low, the prevention and treatment effect on second-instar and fourth-instar larvae is above 94 percent indoors under the conventional dosage and is obviously superior to that on phoxim, chlorpyrifos and other commonly-used medicaments, the prevention effect can reach above 90 percent in a field, and the indoxacarb does not belong to organic phosphorus and is safer in use.

Description

technical field [0001] The invention relates to the prevention and control of agricultural pests, in particular to a new application of using indoxacarb to prevent and control the spodoptera moth. Background technique [0002] Two o'clock moth[ Athetis lepigone (M?schler, 1860)] is a new agricultural pest in my country's summer corn production areas. [0003] According to relevant records, in July 2005, it was first discovered in Shijiazhuang, Hebei Province in China that the two-spot moth damages summer corn seedlings, bores the base of the stem, causes the seedlings to wilt and die, or bites off the corn roots, leading to lodging, causing Serious lack of seedlings and monopoly, this is the first report in China. According to reports, in 2010, Noctuid moths commonly occurred in the central and southern summer corn areas of Hebei Province. In 2011, they broke out in Hebei, Henan, Shandong, Shanxi, Anhui, Jiangsu and other provinces, with an area of ​​more than 30 million m...
