You can t use medicine when citrus blooms, what should I do if the orange tree has insects?

Citrus is still very sensitive to drugs when flowering, and improper or excessive use of drugs at this time is easy to cause drug damage, resulting in a large number of flowers and fruits, or causing fruit deformity and stunted development. Citrus flowering period is divided into early flowering stage and full flowering stage, flowering period, early flowering period (flower bud) and flowering period can be used in a timely manner, mainly to avoid the full flowering period of medication, because the agent is sensitive to the flower is easy to cause serious flower fall, affecting the yield. When the adult insects are unearthed, the ground is sprayed for control, and 200 grams of phosphine emulsifiable concentrate and 15 kg of fine soil can be mixed and sprinkled on the ground per mu, and it can be applied once every other week, and it can be applied twice in a row, which can effectively prevent flower buds and maggots from going to the tree.

In the flowering period, organophosphorus pesticides can not be used, and emulsifiable concentrate-type agents can not be used. It is recommended that the suspension form is safer. In addition to paying attention to the damage to flowers and leaves of some pesticides during use, we should also pay attention to the temperature characteristics of the pesticides used, so as to achieve drug safety and good control effect.

For the selection and use of foliar fertilizers, this type of nutrient does not have so many requirements, and it can also help fruit trees to pull shoots, and it can also promote aging. Therefore, you can choose any one of the three of phosphorus dipotassium, high nitrogen macroelement fertilizer or trace element zinc fertilizer, of course, according to the growth of fruit trees.

<> fruit growers often spray pesticides to control pests and diseases such as spider mites, flower bud maggots, thrips, scabs and anthracnose when citrus is blooming, so as to ensure the smooth growth of citrus. The specific medication should be based on the actual situation of the orchard, the varieties with strong resistance to canker disease, and the disease does not appear in their own orchards and surrounding areas, so they do not need to add ulcer drugs. A special trap is placed in a citrus grove and the smell released by the trap attracts and kills pests.

When using trapping and killing insects, we must be diligent in replacing the trap device to avoid the failure of the trap agent and the destruction of the trap device. to reduce the dosing of medications.

For pests that appear on the surface of orange trees, it is necessary to spray the orange trees, and homemade pesticides can generally be used to eliminate the pests. First of all, you need to prepare some dried chili peppers and cut them into small pieces, then boil them with water, add washing powder to them after cooling, mix them well and spray them on the orange branches.

For the parts of the orange tree that are more insect-infested, they need to be pruned properly. First of all, you need to choose scissors with a sharp edge, and then use scissors to cut off the parts of the orange tree branches that have the most insects, and also need to cut off the branches and leaves of the orange tree that are not growing well to avoid healthy branches from being attacked by pests.

Orange trees produce pests that grow on the surface of the trunk, and naturally there are also pests that grow inside the orange tree, and for these pests, insecticides can be injected directly into the trunk of the orange tree using a syringe. And before injection, you need to look for the wormhole on the stem of the orange branch, and then inject into the wormhole.

In the later maintenance of orange trees, it is necessary to provide the right amount of water for the plants, soak all the soil, and also provide reasonable nutrients for the orange trees, improve the growth rate of the plants, and also provide suitable light for the orange trees, so that the plants can photosynthesize normally and grow more vigorously.

After pruning the branches in winter, all branches should be destroyed and insecticides should be sprayed in time to kill the eggs. In the flowering and pumping stage of orange trees, most of the aphids are adsorbed on the new slightly, which can be suppressed by wiping, and for other branches, they can be manually removed with a brush, and the recommendation for larger insect pests is drug control. In addition, the fertilizer and water management of the orchard should be strengthened, the branches and leaves will flourish, and the fruit trees will grow healthily, so as to improve the epidemic prevention ability of the fruit trees, and then prevent the invasion of diseases and insects.

It is necessary to treat citrus before it blooms. 7 to 15 days before flowering, spray pesticides to control pests and diseases, focusing on the prevention and control of bud insects, thrips, red spiders, canker disease, insecticides + fungicides + red spider drugs + canker drugs + foliar fertilizer. Focus on the prevention and control of thrips during flowering, and spray thrips during the flowering period, preferably alone.

The leaves that have pests and diseases should be removed in time, and some fertilizer and water management should be emphasized, and some insecticides should be used in small quantities.

Summary. This orange has common medicines for insects, as well as thiobenone, dacarin, alkyne, bromodifen, dimethyl and so on.

Before and after flowering (March-May) and autumn (September-November) are the key periods for the control of spider mites: the population density of 1-2 leaves before flowering, and 5-6 leaves after flowering and autumn need to be controlled. The spring shoot extraction stage, the young fruit stage and the fruit expansion stage are the main periods for rust lice control

The back of the spring shoots of the year first appeared rust-colored; When the density of insects on leaves or fruits reaches 2-3 per leaf, immediate control [Bixin] [Bixin].

When the orange tree blooms, there is a bug to spray what medicine.

Now the orange tree has bloomed, the leaves of lice, what medicine can be used.

What medicine to use for insects in orange trees should be determined according to the specific insect infestation. If it is a red spider, you can use 50% mite instead of 1500 times of emulsifiable concentrate, 50% Tork 1500 times or 73% of 2000-2500 times of gite emulsifiable concentrate, etc., and the drug should be used alternately. If it is a rust spider, you can use 50% mites to treat 1500 times of emulsifiable concentrate, and 20% mites to die 1500 times of liquid.

If it is a leaf miner, you can use 5% imidacloprid emulsifiable concentrate 2000-3000 times.

When the orange tree blooms, there are insects on the leaves, which can be sprayed with pesticides. If it is an aphid, dicofol can be sprayed; If it is a cotton worm, you can spray deltamethrin or insecticide. These types of pesticides are relatively safe and will not affect the fruit hanging.

Okay, thanks.

You're welcome dear.

Orange trees can be sprayed with pesticides when they bloom, but if there are no serious pests or diseases, try not to spray pesticides during the flowering period, so as not to affect insect pollination and reduce fruit set. The flower buds of citrus, except for the pure flower buds, are mixed buds. Mixed buds generally differentiate after fruit harvest and before bud break in the following spring (mainly from December to March).

Kumquat shoots and blooms several times a year, and each time the shoots stop growing, they differentiate once. The mixed buds are born a few nodes near the apex of the fruiting mother branch. After germination, the fruiting branches are extracted and the flowers and fruits are flowered at the tip of the fruiting branches.

In the process of development, citrus fruits have two obvious peaks of falling flowers and fruits, the first time is within a few days to two weeks after flowering, and falls off together with the fruit stems, commonly known as "falling flowers". The main reason is that the fertilization is not disordered and the growth hormone that is transmitted by pollen is not good. The second time is one month after the flowering, in June, also known as "June Fruit Fall".

The main reasons are insufficient nutrients, lack of endogenous hormones, or imbalance; Too much moisture or drought can also cause fruit drop in June. This drop had a great impact on yield.

Summary. Daily maintenance and management of orange trees: light, potted orange trees are placed on the balcony in a bright and ventilated place, the light intensity is a little higher, it is better to flower and set fruits, the light is dark and easy to grow, the flowers are less, and the fruit is less.

Water, orange trees are more drought tolerant, dry and watering, the soil is not dry and not watered, afraid of waterlogging, it is better to see dry and wet, look at the dry and humid of the potting soil before watering, it doesn't matter if the soil is dry. Nutrients, orange trees like fertilizer, fertilizer and water once half a month in the growing season are better, plant growth is better and more vigorous, and the leaves are often sprayed with potassium dihydrogen phosphate, which can promote plant flowering and fruiting.

Hello, it's a pleasure to serve you, I'm a recreation tutor and I've seen your problem. Due to the large number of consultations now, I will answer the questions one by one and inquire and summarize the number of Bu Hui for you, please be patient. Please do not close the order too early, and provide more effective cavity bending information in order to give you a better answer, thank you for your understanding and support!

When the pro-orange tree blooms and hangs fruit, there are insects on the leaves, if you are careful to observe that the fruit insects are not very many, you don't need to care about it withering, generally this situation is that there are insects in the soil eggplant, I suggest you change some soil.

Solution: You can go to the flower shop or your agricultural company to see, air transport to buy insecticides, under normal circumstances, a package of watering cans, spray the back of the plant leaves, branches, the rest of the potting soil, spray three times a week, you can get rid of insect pests and scale insects.

Daily maintenance and management of orange trees: light, potted orange trees are placed on the balcony in a bright and ventilated place, the light intensity is a little higher, it is easier to flower and set fruits, the light is quiet, the silver line is dark, it is easy to grow, the flowering is less, and the fruit is less. Water, orange trees are more drought tolerant, dry and watering, the soil is not dry and not watered, afraid of waterlogging, it is better to see dry and wet, look at the dry and humid of the potting soil before watering, it doesn't matter if the soil is dry.

Nutrients, orange trees like fertilizer, fertilizer and water are better once half a month in the growing season, plant growth feast is better and more vigorous, and the leaves are often sprayed with potassium dihydrogen phosphate, which can promote plant disturbance and flowering and fruiting.

You can also spray pesticides on a regular basis, and then slowly soil the orange tree, my family is to apply more fertilizer, loosen the soil, and water the right amount.
