Embodiment 1

[0014] Embodiment 1: Toxicity determination of spirotetramat and imidacloprid, acetamiprid or thiamethoxam compound

[0015] 1. Combined toxicity test of spirotetramat and imidacloprid

[0016] Test object: Sitobion avenae (Fabricius) was used as the test object. Sensitive test insects were collected from the Teaching and Experimental Farm of Sichuan Agricultural University in Ya'an City, Sichuan Province, and resistant test insects were collected from Duoying Town, Ya'an City, Sichuan Province.

[0017] Test agents: spirotetramat (Bayer Crop Science, Germany), imidacloprid (Jiangsu Yangnong Chemical Industry Co., Ltd.)

[0018] Test method: refer to "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 wheat leaves (treated with agar for moisture retention) are placed, and 5 dishes are connected for each treatment, and sprayed with a potter spray tower at a pressure of 15PSI, one dish is sp...

Embodiment 2

[0049] Embodiment 2: processing and field test of spirotetramat and imidacloprid compound preparation

[0050] Spirotetramat 20.83g, imidacloprid 1.05g, sodium lignosulfonate 5.5g, calcium dodecylbenzenesulfonate 4g, xanthan gum 0.5g, add water to 100g.

[0051] The above components are uniformly mixed according to the ratio of the formula, and after grinding and / or high-speed shearing, a 21% spirotetramat imidacloprid suspension concentrate is obtained. (The mass ratio of spirotetramat and imidacloprid is 20:1)

[0052] 21% spirotetramat imidacloprid suspending agent, 240g / L spirotetramat suspending agent and 10% imidacloprid wettable powder are all according to active ingredient 30g / hm 2 Add water to dilute the spray and use it to control radish aphids. One day after spraying, the compound drug was 91.6%, far greater than the control effect of 240g / L spirotetramat suspension concentrate of 73.4% and the control effect of 10% imidacloprid WP of 70.7%. Significant differenc...

Embodiment 3

[0054] Example 3: Processing and field test of spirotetramat and acetamiprid compound preparation

[0055] 2.08g of spirotetramat, 41.67g of acetamiprid, 2g of sodium lauryl sulfate, 3g of sodium lignosulfonate, 5g of NNO, 10g of white carbon black, and 100g of kaolin.

[0056] The active ingredient spirotetramat and acetamiprid, various auxiliary agents and fillers are fully mixed in proportion, and after being pulverized by an ultrafine pulverizer, a 42% spirotetramat-acetamiprid wettable powder (spirotetramat) is obtained (spirotetramat). The mass ratio of ester to acetamiprid is 1:20)

[0057] 42% spirotetramat · acetamiprid wettable powder, 240g / L spirotetramat suspending agent and 15% acetamiprid suspending agent were all formulated according to the active ingredient 30g / hm 2 Add water to dilute the spray, be used to control rice planthopper, 3 days after spraying, 42% spirotetramat · acetamiprid wettable powder, 240g / L spirotetramat suspension concentrate and 15% aceta...

Abstract

The invention discloses a pesticide composition and application thereof in agriculture. The composition comprises the effective components of screw worm ethyl and anabasine class pesticide, wherein the mass ratio of the screw worm ethyl and the anabasine class pesticide is 60:1-1:80. The composition has a synergistic action, is especially obvious to resist pests, also can lower the application quantity and delay the generation and development of resistibility. The composition can be used for preventing and treating various pests in agriculture and is especially suitable for preventing and treating resistant pests with sucking mouth parts, such as plant hoppers, aphides, whiteflies, leafhoppers and the like.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition containing spirotetramat, and its application in the control of agricultural pests. Background technique [0002] Spirotetramat (Spirotetramat), a tetronic acid insecticide developed by Bayer Company, belongs to the same class of compounds as the insecticide and acaricide Spirodiclofen and Spiromesifen. Spirotetramat has unique action characteristics, has two-way systemic conduction performance, can move up and down in the whole plant body, and reaches the leaves and bark, so as to control pests on the inner leaves of lettuce and cabbage and on the bark of fruit trees. Another feature is its long-lasting effect, which can provide effective control for up to 8 weeks. Spirotetramat can effectively control various piercing-sucking mouthparts pests, such as aphids, thrips, psyllids, mealybugs, mealybugs and scale insects. However, long-term use of spirotetramat alo...
