Embodiment 1

[0022] Example 1 Toxicity determination of tebufenfen, chlorpyrifos and different ratios to Tetranychus cinnabarinus

[0023] Female adult mites of Tetranychus cinnabarinus were collected from the field, and after three generations of indoor rearing, female adults with uniform growth were selected as the test insects for this experiment. The test method refers to "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006" and "People's Republic of China Agricultural Industry Standard NY / T1154.12-2006". Using the glass slide dipping method, that is, cut the double-sided tape into 1cm × 2cm and stick it on one end of the glass slide, stick the back of the adult mite of Tetranychus cinnabarinus on the tape, 35 to 40 mites per slide, and check under the microscope after 4 hours , After picking out dead mites, add live adult mites. Place the glass slide with the female adult mite stuck in the liquid medicine for 5 seconds, then take it out, use filter paper to abso...

Embodiment 2

[0032] Example 2: Toxicity determination of tebufenpyrad, profenofos and different ratios to Tetranychus urticae

[0033] Female adult mites of Tetranychus urticae were collected in the field, and after three generations of indoor breeding, female adults with uniform growth were selected. The test method refers to "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006" and "People's Republic of China Agricultural Industry Standard NY / T1154.12-2006". Adopt glass slide dipping method, test method and statistical method are the same as embodiment 1. The test results are shown in Table 2.

[0034] Table 2 Toxicity determination of tebufenpyrad, profenofos and different ratios to Tetranychus urticae (24h)

[0035]

[0036] It can be seen from Table 2 that when the weight ratio of tebufenfen and profenofos is mixed between 30:1~1:80, the co-toxicity coefficient of each proportion has reached more than 120, showing a certain synergistic effect; When the weig...

Embodiment 3

[0037] Example 3: Toxicity Determination of Tebufenpyrad, Quetiafos and Different Proportions to Cotton Aphids

[0038] The test method refers to "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006" and "People's Republic of China Agricultural Industry Standard NY / T1154.9-2006". The test insects were adult cotton aphids (Aphis gossypii Glover) raised on cotton seedlings in the greenhouse, collected from Xixiang, Baoan District, Shenzhen. The original drug was prepared into the required test drug according to the conventional method. Fresh cotton leaves (treated with agar for moisturizing) are placed in a petri dish with a diameter of 9 cm, and 5 dishes are connected for each treatment, sprayed under a pressure of 15PSI with a potter spray tower, one dish is sprayed at a time, and each dish is sprayed with 2 milliliters, and the blank control was sprayed with the same amount of water. 6-7 concentration gradients were set for each treatment. Insert 30 a...

Abstract

The invention relates to a pesticide composition. The composition comprises active ingredients of tebufenpyrad and an organophosphorus pesticide, wherein the mass ratio of the tebufenpyrad to the organophosphorus pesticide is 30:1-1:80. The composition has a synergized effect, can reduce medicament cost, and contributes to delaying the development of resistibility of the pests and the mites. The composition is used for preventing and controlling the pests and the mites on the plants, and particularly can be used for preventing and controlling cotton aphids, carmine spider mites and two-spotted spider mites.

Description

technical field [0001] The invention relates to a pesticide composition, in particular to a pesticide composition containing tebufenpyrad. 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. Among agricultural pests, Homopteran pests such as aphids, whiteflies and herbivorous mites are prone to resistance due to their short reproduction cycle and large reproduction volume, resulting in a great drop in the control effect of some commonly used pesticides. The control effects of imidacloprid, which is mainly used to control aphids, and pyridaben, which is mainly used to control p...
