Embodiment 1

[0017] Example 1: Compound toxicity test of flonicamid and imidacloprid, acetamiprid or thiamethoxam

[0018] 1. Toxicity test of flonicamid and imidacloprid

[0019] Flunicamid and imidacloprid compound synergistic test, using the radish aphid as the test object. The specific method is:

[0020] Radish aphid (Lipaphis erysimi): an adult aphid raised with radish seedlings in the greenhouse. Sensitive test insects were collected from Xixiang, Baoan District, Shenzhen, and resistant test insects were collected from Qingxin County, Guangdong. The test drug flonicamid was from Sumitomo Co., Ltd., and imidacloprid was from Jiangsu Yangnong Chemical Group Co., Ltd. The original drug was prepared into the required test drug according to the conventional method. The test method refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006". The test adopts a petri dish with a diameter of 9 cm in which cabbage leaves (treated with agar for moisture retent...

Embodiment 2

[0050] Example 2: Preparation of compound preparation of flonicamid and imidacloprid and field test of medicament

[0051] 97.6% flonicamid technical 5.12g

[0052] 95% imidacloprid technical 5.26g

[0053] Sodium dodecylbenzenesulfonate 2.3g

[0054] Phenol formaldehyde resin polyoxyethylene ether 3.8g

[0055] Carboxymethylcellulose 3.35g

[0056] Deionized water up to 100g

[0057] Add the above components into the mixer in sequence according to the amount of the formula, shear and stir evenly to obtain 100 g of 10% flonicamid imidacloprid emulsion in water (the mass ratio of flonicamid to imidacloprid is 1:1).

[0058] Dilute and spray 10% flonicamid imidacloprid aqueous emulsion with 10 g / ha of active ingredient in water to control cabbage aphids. The control effect was 93.3% one day after application, and the 30% flonicamid aqueous emulsion and 20% imidacloprid aqueous emulsion were used according to the same method and dosage, and the control effects were 78.4% and...

Embodiment 3

[0060] Example 3: Preparation of compound preparation of flonicamid and acetamiprid and field test of medicament

[0061] 97.6% flonicamid technical 20.49g

[0062] 95% Acetamiprid Technical 1.1g

[0063] Fatty acid polyoxyethylene ether 3.4g

[0064] Sodium Naphthalene Sulfonate Formaldehyde Condensate Sodium Salt 2.5g

[0065] Xanthan gum 1 g

[0066] water up to 100g

[0067] The above components are mixed uniformly according to the amount of the formula, and after grinding and / or high-speed shearing, 100 grams of 21% flonicamid acetamiprid suspensions are obtained (the mass ratio of flonicamid and acetamiprid is 20: 1).

[0068] Dilute and spray 21% flonicamid acetamiprid suspending agent with 30 g / ha of active ingredient and add water to control rice planthopper (brown planthopper accounts for more than 95%, and its resistance to imidacloprid is 186.8 times). 3 days after application, the control effect was 92.3%. When 24% flonicamid suspension concentrate and 20% a...

Abstract

The invention discloses a pesticide composition and application thereof in agriculture. The effective component of the composition comprises flonicamid and neonicotinoid insecticides with a mass ratioof 80:1-1:80. The composition has the advantage of synergetic effect, obviously for resistant pests, reduces the dosage and delays resistance development, and is used for preventing and treating pests with obvious resistance, and is especially suitable for preventing and treating rice planthopper, thrips and aphid with resistance.

Description

technical field [0001] The invention relates to a pesticide composition and application thereof, in particular to a pesticide composition containing flonicamid, which is used to prevent and control resistant pests on plants. Background technique [0002] In the actual process of agricultural production, chemical control is an important means of preventing and controlling pests in agricultural production. In the process of chemical control, the most likely problem is the emergence and development of resistance of bacteria and pests. In agriculture, resistant pests are prone to have short reproductive cycles, large reproductive numbers, and significant generational overlap. [0003] Among agricultural pests, Homopteran pests are prone to resistance due to their short reproductive cycle and large reproductive capacity. For example, rice planthoppers have caused outbreaks in my country in recent years, and the emergence of populations highly resistant to imidacloprid is one of...
