Embodiment 1

[0022] Example 1 Thiacloprid, Abamectin and the Toxicity Measurement of Different Proportions to Brown Planthopper

[0023] The test refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006" and "The People's Republic of China Agricultural Industry Standard NY / T1154.11-2008", using the rice stem dipping method. Utilize DPS data statistical analysis software to find virulence regression equation and LC 50 The joint toxicity test adopts the co-toxicity coefficient (CTC) method proposed by Sun Yunpei et al. in 1960.

[0024] The formula for calculating the co-toxicity coefficient is as follows:

[0025] Measured toxicity index (ATI) = (standard drug LC 50 / Test agent LC 50 )×100

[0026] Theoretical toxicity index (TTI) = A drug ATI × the percentage of A in the mixture + B drug ATI × the percentage of B in the mixture

[0027] Co-toxicity coefficient (CTC) = (mixture ATI / mixture TTI) × 100

[0028] When CTC≤80, the composition exhibits antago...

Embodiment 2

[0034] Example 2 Toxicity determination of thiacloprid, avermectin and different ratios to pear psyllid

[0035] The test refers to the "People's Republic of China Agricultural Industry Standard NY / T1154.7-2006". Using the leaf dipping method, first conduct a pre-experiment on the test agent, and then dilute it into 5 gradient concentrations according to the doubling relationship, soak the fresh pear leaves for 10 seconds, and put the pear leaves on the table after the liquid on the surface of the pear leaves is dried. in a pre-prepared test tube. Each treatment was repeated 3 times, and each time 40 third-instar psyllid nymphs were placed in a 2.5cm×20cm test tube, allowing the psyllid to eat the pear leaves in the test tube. Set water blank control. The death of pear psyllid was investigated 24 hours after inoculation. Utilize DPS data statistical analysis software to find virulence regression equation and LC 50 The joint toxicity test adopts the co-toxicity coefficient ...

Embodiment 3

[0040] Embodiment 3: the preparation method of 80.5% thiacloprid-abamectin wettable powder

[0041] 95% Thiacloprid Technical 84.21g

[0042] 92% Abamectin original drug 0.54

[0043] Calcium lignosulfonate (dispersant) 10.2g

[0044] Sodium lauryl sulfate (wetting agent) 3.1 g

[0045] Clay (carrier) make up to 100g

[0046] Weigh various components such as thiacloprid and abamectin according to the weight ratio, and go through the drying and cooling of fillers; the mixing, grinding and mixing of fillers, original drugs and additives; the packaging of wettable powder products and other processes. Prepare 100 grams of 80.5% thiacloprid-abamectin wettable powder (the weight ratio of thiacloprid and abamectin is 160:1).

Abstract

The invention relates to a pesticide composition. Effective components of thecomposition include thiacloprid and abamectin, wherein the content of the thiacloprid is 0.5-80 percent by weight, the content of the abamectin is 0.5-20 percent by weight, the total content of the thiacloprid and the abamectin is 1-90 percent by weight, and the weight ratio of the thiacloprid and the abamectin is 160:1-1:40. The pesticide composition can generate synergistic function, achieve a remarkable effect in resisting pests, and simultaneously reduce the use amount and delay the resistance development of the pests. The composition can be used for preventing and killing resistant pests on crops, in particular for preventing and killing high-resistance rice planthopper, pear psylla and aphid.

Description

technical field [0001] The invention relates to an insecticidal composition, in particular to an insecticidal composition containing thiacloprid as an active ingredient, which is used to prevent and control resistant pests on crops. Background technique [0002] In agricultural production, chemical control is an important means of preventing and controlling crop diseases and insect pests. In the process of chemical control, due to the long-term and irrational use of chemical pesticides, the resistance of pests and germs has been increasing, which has brought great difficulties to the control work. [0003] Brown planthopper and pear psyllid are two important pests on rice and pear trees, respectively. In recent years, the resistance of the two pests has developed rapidly, so that many effective insecticides have successively weakened the control effect. For example, imidacloprid drug, Shen Jinliang determined that the resistance of brown planthoppers in Nanjing Jiangpu, Gu...
