Problems solved by technology

[0009] The technical problem to be solved in the present invention is to overcome the following defects in the prior art: 1, adopt the spraying mode to prevent and treat the banana thrips by spraying, the medicinal liquid is more difficult to contact the thrips worm body, the control effect is relatively poor, and the number of times of spraying is relatively low. Many, high cost; 2. Using flower bud injection to prevent and control thrips, spraying requires two people to cooperate, time-consuming, and easy to break flower buds during the operation; 3. Soil application and leaf sheath application to control banana pseudostem weevil, Usually highly toxic pesticides, the leached and absorbed pesticides are difficult to reach the inner layer of the pseudostem, the utilization rate is low, and the unabsorbed pesticides leached into the environment, causing environmental pollution

Embodiment 1

[0046] Example 1 Banana Plant Pseudostem Injection of Imidacloprid to Control Thrips

[0047] When the banana plants are budding, use the back-barrel special spraying device to spray and control banana thrips. Use 70% imidacloprid water-dispersible granules to dilute to 200 times of liquid, and pour the prepared drug solution into the back-barrel special spraying device. In the back bucket 1, the pesticide applicator carries the back bucket 1 on his shoulder, holds the handle 10 of the continuous drug irrigation device, and puts the needle end 12 of the injection needle downward on the banana pseudostem at a height of 1-1.5m from the ground. Insert the injection needle 6 into the banana pseudostem at an angle of 45° to the pseudostem, push the handle 10 of the continuous dosing device with your fingers, and inject the 70% imidacloprid water-dispersible granules 200 times liquid medicine in the back barrel 1 into the banana In the pseudostem, the 70% imidacloprid water-dispersi...

Embodiment 2

[0056] Example 2 Banana Plant Pseudostem Injection of Spirotetramat to Control Thrips

[0057] When the banana plants are budding, use the back-barrel type special application device described in Example 1 for pesticide application, select 22.4% spirotetramat suspending agent to dilute to 200 times of liquid, and pour the prepared medicinal solution into the back-barrel type In the back barrel 1 of the special spraying device, the sprayer carries the back barrel 1 on his shoulders, holds the handle 10 of the continuous sprayer, and puts it on the banana pseudostem at a height of 1 to 1.5m from the ground, on the needle of the injection needle. The end 12 is in the direction of an angle of 45° with the pseudostem downward, the injection needle 6 is inserted into the banana pseudostem, and the handle 10 of the continuous dosing device is pushed by fingers to dilute the 22.4% spirotetramat suspension in the back bucket 1 into The 200-fold medicinal solution is injected into the p...

Embodiment 3

[0064] Example 3 Banana Plant Pseudostem Injection Chlorpyrifos Control Pseudostem Weevil

[0065] Banana plants are in the danger period of pseudostem weevil, and the back-barrel type special application device described in Example 1 is used for pesticide application, and 48% chlorpyrifos EC is used to dilute it to 200 times of liquid, and the prepared medicinal solution is poured into the laboratory of Example 1. In the back bucket 1 of the back-bucket type special spraying device described above, the sprayer carries the back bucket 1 on his shoulders, holds the handle 10 of the continuous drug irrigation device, and puts it on the banana pseudostem at a height of 1-1.5m from the ground on the banana plant. Insert the injection needle 6 into the banana pseudostem in the direction where the needle end 12 of the injection needle is downward and at a 45° angle to the pseudostem, and push the handle 10 of the continuous dosing device with your fingers to dispense 48% chlorpyrifos...

Abstract

The invention discloses a banana thrip and odoiporus longicollis oliver prevention and control method. According to banana thrip prevention and control, during the squaring stage of banana plants, 70% imidacloprid water dispersible granule 200-fold liquid or 22.4% spirotetramat suspending agent 200-fold liquid is selected, a back barrel type special pesticide application device is used for injecting liquid pesticide into banana cauloids, and 20 ml of the liquid pesticide is injected into each banana plant. According to odoiporus longicollis oliver prevention and control, when odoiporus longicollis oliver causes harm, 48% chlorpyrifos missible oil 200-fold liquid is selected, the back barrel type special pesticide application device is used for injecting the liquid pesticide into the banana cauloids, and 20 ml of the liquid pesticide is injected into each banana plant. The back barrel type special pesticide application device is formed by a back barrel, a continuous drencher, a soft tube and an injection needle tube. The method has the advantages that the pesticide application amount is saved, the purposes of reducing the pesticide amount and ensuring the prevention effect are achieved simultaneously, pollution to the environment is reduced, pesticide application labor intensity is reduced, labor cost is saved, operation is convenient, pesticide application is free from limitation of weather conditions, and toxicity of the applied pesticide is reduced.

Description

technical field [0001] The invention relates to the technical field of pest control in banana planting management, in particular to a method for preventing and controlling thrips and pseudostem weevils harmful to bananas by using a special injection application device. Background technique [0002] Banana is one of the main bulk fruits in our country. During the growth of banana trees, they will be harmed by a variety of pests. The pests include pseudostem weevil, bulbous weevil, thrips, brown-footed leaf beetle, spodoptera litura, and red spider. Among them, pseudostem weevil and thistle Horses occur more commonly, but also more difficult to control. [0003] The thrips that harm bananas are Thysanoptera, Thripidae, and yellow-breasted thrips (Thripshawaiiensis (Morgan). The nymphs and adults of thrips suck the juice of banana flower ovaries and young fruits, and the females lay eggs in the epidermal tissue of young fruits. , the plant cells around the eggs are stimulated...
