Problems solved by technology

Because Liriomyza sativus has great mobility, it reproduces rapidly in three states of eggs, larvae, and adults, and the interval between generations is unclear, so it is difficult to grasp the timing of control, and it is difficult for general drugs to reach the microenvironment where the larvae live, reducing the control effect ; Even if some medicines (comprising microbial insecticides) have better control effects, due to the influence of environmental factors, the killing rate of larvae cannot reach 70%, and a single medicine can easily cause pest resistance to medicines, but there are few kinds of medicines to choose from , poor control effect
Because microbial pesticides are greatly affected by natural conditions, especially temperature and humidity, they should be used with caution, and the timing of application must be grasped. Biological pesticides kill insects slowly and need to be combined with other control methods
The main reason for the poor insecticidal effect of existing drugs is their low specificity

Embodiment 1

[0013] A kind of pesticide that is used for preventing and controlling Liriomyzae described in the present embodiment, it is mixed by 50 grams of trichlorfon, 50ml pesticide adjuvant and 10000ml water, and described agrochemical adjuvant is made of the raw material of following weight and appropriate amount of water Mix to form a 75ml mixture: 20 grams of sodium dodecylbenzenesulfonate, 100 grams of edible sugar, and 20 grams of bone glue.

Embodiment 2

[0015] A kind of pesticide that is used for preventing and treating Liriomyzae described in the present embodiment, it is mixed by 25 grams trichlorfon, 25ml pesticide adjuvant and 5000ml water, and described agrochemical adjuvant is made of the raw material of following weight and appropriate amount of water Mix to form a 75ml mixture: 14 grams of sodium dodecylbenzene sulfonate, 150 grams of edible sugar, and 14 grams of bone glue.

Embodiment 3

[0017] A kind of pesticide that is used for preventing and controlling Liriomyzae described in the present embodiment, it is mixed by 75 grams trichlorfon, 75ml pesticide adjuvant and 15000ml water, and described agrochemical adjuvant is made of the raw material of following weight and appropriate amount of water Mix to form a 75ml mixture: 30 grams of sodium dodecylbenzenesulfonate, 70 grams of edible sugar, and 30 grams of bone glue.

[0018] In a kind of pesticide used for preventing and treating Liriomyza according to the present invention, sodium dodecylbenzenesulfonate is an alkaline penetrating agent, edible white sugar is a spreading moisturizer, and bone glue is a protein colloid insecticide or a spreading agent. agent. During specific use, the pesticides described in Example 1-3 are applied to crops, and after 1-3 days, 2000 times of liquid of abamectin (2000 times diluted with water) is applied to crops for protection.

Abstract

The invention relates to a pesticide used for preventing and controlling leaf miners, which is prepared by mixing trichlorphon, pesticide adjuvant and water, wherein the proportion of the trichlorphon (mass), the pesticide adjuvant (volume) and the water (volume) is 1:1:200; and the pesticide adjuvant is of the 75ml of mixture prepared by mixing water and the following raw materials: 14-30g of sodium dodecyl benzene sulfonate, 70-150g of edible white sugar and 14-30g of bone glue. The pesticide has the benefits of improving the pesticide absorption of crops and improving the pesticide toxicity for the larvas of the leaf miners.

Description

technical field [0001] The invention relates to the field of pesticides, in particular to a pesticide and a method for preventing and controlling Liriomyza sativae (including Liriomyza sativae). Background technique [0002] Liriomyza sativae (including Liriomyza sativae) is a kind of resistant pest, which has a wide range of damage, rapid occurrence, severe disasters and difficult control. , Solanaceae and other crops are seriously harmful to cucumbers, celery, peas, cabbage, potato virus-free seedlings, etc., resulting in reduced production or even no harvest. Because Liriomyza sativus has great mobility, it reproduces rapidly in three states of eggs, larvae, and adults, and the interval between generations is unclear, so it is difficult to grasp the timing of control, and it is difficult for general drugs to reach the microenvironment where the larvae live, reducing the control effect ; Even if some medicines (comprising microbial insecticides) have better control effect...
