How to fight peach tree aphids by plant protection drones

If the tree is very large, the electric multi-rotor drone will not be able to fight. First, the penetration of electric aircraft is not enough, because the leaf pressure is not enough, it can only hit the surface layer, not deep.

Second, the battery life is short, if it is a fruit tree seedling, you can also play, but when you encounter a 3-4 year old tree, it takes 1 minute to spray a tree evenly, and you must know that the general flight time of electric drones is 15-20 minutes.

Third, the load is small, combined with the previous two situations, it is needless to say.

Fuel direct drive multi-rotor can go to understand, taking Shenzhen Changfeng Tianma-2A UAV as an example, the engine is used as the flight power, the engine drives the leaf surface to apply super pressure to the water mist, the minimum spray width is 4 meters to improve the operation efficiency, and the leaf surface is blown away so that every drop of water mist can be contaminated with the leaf surface and the back leaf surface. The endurance time is 1-3 hours, the maximum load is 70 kg, and the operation volume is improved.

Hello! You are a peach tree for a few years, and a small peach tree can use a drone, and if it is a big peach tree, the effect of using a drone is average.

The big peach tree is too tall, and it is difficult to shoot down the drone's medicine, which means that it cannot be hit under the tree at all or the effect of the medicine is not good.

Hope mine can help you!

How to control aphids in peach trees Effective methods of aphids.

The key to peach aphid prevention and control is to be careful, careless or not, through the formalities, symbolic spraying should not be returned, one is to use imidacloprid, pymetrozine, thiamethoxam, acetamiprid and other agents alternately to prevent the same agent from being resistant to the same agent for a long time, the second is to spray the back of the leaf to spray finely, the nozzle head is upward, sprayed from bottom to top, and the third is to the occurrence stage of winged aphid, the yellow sticky insect board can be hung in the orchard, which can eliminate a part of the winged aphid and affect its reproduction.

Fourth, you can try to catch some ladybugs and put them in the orchard, and use natural enemies to eat aphids.

Peach tree aphid control methods.

1. Strengthen orchard management. Combined with spring pruning, cut off the damaged branches and burn them intensively.

2. Reasonable supporting cultivation. Crops such as tobacco and cabbage should not be planted between or near the rows of peach orchards to reduce the summer breeding grounds of aphids.

3. Protect natural enemies. Ladybugs, aphid-eating flies, grass lacewings, and parasitic wasps are the natural enemies of aphids, so broad-spectrum pesticides should be sprayed as little as possible, and spraying pesticides when there are many natural enemies.

Prevention and control of peach tree aphids, commonly used drugs are acetamiprid, imidacloprid, pymetrozine, etc., from the application of production in recent years, aphids are easy to resist a variety of commonly used drugs, according to relevant research data, at present in different regions, there are aphid populations resistant to imidacloprid, pymetrozine and other drugs, aphids appear resistant to the area, can be changed to halodimidiliprole, halodioxapyr and other drugs according to local conditions, or these drugs are used in combination with imidacloprid and pymetrozine. 1. When germinating and germinating in early spring, the stone sulfur mixture is used normally;

2. Peach blossom dew red stage: halodioxapyr (times or 50% 10,000 times -12,000 times);

3. Late flowering stage (80% flowering): spiral ethyl ester (22%-4000-5000 times).

Be sure to grasp the period of medication, the water consumption should be sufficient, the spray should be uniform and thorough, the interval time is 7-10 days, pay attention to alternate use when using, so as not to produce aphid resistance, peach powder aphid can be added to the liquid laundry detergent to increase adhesion, remove the wax powder on the insect body, pay attention to the fluoroxapyr used twice in a growing season.

Biological control: protect the natural enemies of pests, mainly turtle ladybugs, heterochromatic ladybugs, seven-star ladybugs, lacewings, aphid flies, down mites, spiders, parasitic wasps, etc., in the case that natural enemies can inhibit aphids, the number of spraying can be minimized.

Once the peach aphid occurs in large size, it is difficult to kill it all 1-2 times, so it is best to spray it carefully before rolling the leaves. For those that have been curled, 600-700 times Avi Gaoflucloxaploprid or acetamiprid can be carefully sprayed 'especially at the leaf curl', once every 5-7 days, 2-3 times in a row can be controlled. At the same time, heart-eating insects and blind bugs are also controlled.

The whole plant can be eliminated by spraying "monocrotophos", "methamidophos", "aphid lice net", "enemy killing", "kung fu pyrethrin", be careful not to spray dichlorvos, dimethoate, oxidized dimethoate, so as not to cause sensitive yellow leaf fall!!

Acetamiprid (brand name: Split tooth) and imidacloprid are more effective. The former has a good effect at high temperatures.

Peach tree aphid agents: fludicariliprole, halodioxapyr, dinotefuran, thiamethoxam, pymetrozine, isoprocarb, which are not recommended by the country but have good effects, such as methocarb, carbosulfan, endosulfan, etc. Pymetrozine thiamethoxam + isoprocarb or carbofuran butathine can be sprayed.

Peach trees are the most critical source of aphid prevention.

The period is the first time after the dew period and the flowers!

The most common ones are imidacloprid and pymetrozine, etc.! Later the temperature rises with acetamiprid! Now imidacloprid resistance is quite strong!

It is recommended to use Dow Agro Lig (halodimidoxonil), the patented ingredient is non-resistant, and the duration of effect is more than 2 times that of conventional drugs.

Imidacloprid can also be used with cypermethrin (Shunyi, Beijing), which has a good effect on the control of aphid peach heartworm.

BAI control methods for peach tree aphids.

1. Strengthen the management of DU orchards. Combined with spring.

The key to peach aphid prevention and control is to be careful, careless, through the formalities, symbolic spraying is also not possible, one is to use imidacloprid, pymetrozine, thiamethoxam, acetamiprid and other agents alternately to prevent the same agent from being resistant to the same agent for a long time, the second is to spray the back of the leaf to spray carefully, the nozzle head is upward, sprayed from bottom to top, and the third is to the winged aphid occurrence stage, you can hang the yellow sticky insect board in the orchard, which can eliminate a part of the winged aphid and affect its reproduction.
