The best time to choose the medicine of apricot trees is in the spring. The insect pests of apricot trees in spring mainly include aphids and scale insects. The main diseases are gelatinous disease, brown rot, bacterial perforation disease, etc.

The control of apricot diseases and insect pests is mainly prevention and comprehensive control. Choose biological pesticides or chemical pesticides with high efficiency, low toxicity, low residue, and light lethality to natural enemies, and use different types of pesticides alternately. The spraying period, the control object, the type and concentration of the agent are as follows:

Spray 5 Baumé stone sulfur mixture solution before germination to prevent and control scale insects and various diseases.

15 20 days after flowering, spray 50% carbendazim 800 1000 times + 10% imidacloprid 3000 times solution to prevent and control various diseases and aphid damage, and spray fungicides every 15 days to continue to prevent and control diseases.

Before the apricot tree blooms, the diluted boric acid solution can be used, which can play the role of flower and fruit preservation and improve the fruit setting rate. In addition to flowering and fruit preservation plants, before the apricot tree blooms, you can also spray 4 5 Baumé stone sulfur mixture or 1:100 Bordeaux liquid, which can play a bactericidal role and prevent disease breeding.

After the apricot tree falls flower, it can be sprayed with 80% mancozeb 800 times immediately, and then every 10-14 days, spray 50% carbendazim wettable powder 600 times, 70% methyl tobuzine 600-800 times, 75% chlorothalonil wettable powder 500-600 times. If you find that there are insect pests, you need to spray insecticides according to the type of insect pests, if you are infected with apricot weevils, you can spray 20% rapid culling 2000 times liquid, 50% carbendazim 600 times liquid, if infected with red spiders, scale insects, you can spray 2000-3000 times of liquid, 1000 times of rapid culling.

Apricot. 2. Management of the flowering period of apricot trees.

1. Thinning flowers and fruits: During the flowering period of apricot trees, we must pay attention to thinning flowers and fruits, too many flower buds will affect flowering, you can thin off a part, and you can also reduce the consumption of nutrients, which is conducive to later flowering.

2. Promote pollination: During the flowering period of apricot trees, in order to improve the pollination rate, the method of releasing bees during the flowering period can be adopted. If the effect is not good, manual pollination can be carried out.

3. Proper watering: During the flowering period of apricot trees, we should pay attention to proper watering, maintain good humidity, and prevent over-drying and over-wetting.

In early April, spray before flowering to prevent pests.

Apricot is a very nutritious fruit, the apricot tree flowering period is 3-4 months, and the fruiting period is 6-7 months.

Young trees (1-2) years of fertilization, the first to take the principle of thin fertilizer diligent application, the second year in mid-April, late June each top dressing a top dressing to fast-acting compound fertilizer-based, each plant 3 taels, late September to October autumn base fertilizer (pigs, chickens, manure) appropriate amount of watering, each top dressing must be watered, watering during the drought period, drainage in the rainy season. Trees sweep the arbores after they have fallen leaves.

In early April, 2 kg of special fertilizer is used for each tree to chase fruit trees, and 6 pits of 40 cm are dug around the canopy projection, and 6 are buried with fertilizer and watered.

Cultivating and weeding in May. In mid-June, the fruit swelling period was cultivated and weeded, and 2 kg of special fertilizer for fruit trees was chased, the method was the same as above, avoiding the pit of the last top dressing, watering, spraying to prevent and control aphids, and entering the Futian to see the moisture watering.

In October, the autumn application of base fertilizer, pig and chicken manure is the best, other farm fertilizer can also be, the method is around the tree 2 feet away from the trunk, dig 6 to 8 radial ditches, the depth is 30 cm near the tree, and gradually deepen to 50 cm to the crown projection, apply fertilizer and then cover the soil, see the moisture watering, clean the apricot orchard after falling leaves, and prevent disease.

Apricot tree insect control can generally be sprayed about half a month before the apricot tree germination in spring (early March). When spraying, you can spray 3-5 Baumé stone sulfur mixture to eradicate the source of overwintering disease and insects, and you can also spray aphid control drugs after flowering.

For apricot trees, I think it is better to spray in the beginning of spring or in the early autumn, which is more conducive to rapid growth, yes. Able to achieve good results.

It is best to spray apricot trees in spring, not when they are flowering or fruiting.

Hit once before flowering, once when fruiting, and once when the fruit is almost ripe.

It should be sprayed before budding in the spring, and the eggs on the tree should be killed by medicine.

Apricot trees are sprayed with acetamiprid and other insecticides to control aphids after flowering, and the effect is relatively good. If it is sprayed with stone sulfur mixture, it is necessary to shoot the dust tung for about half a month (before the flower buds germinate) before the apricot tree blooms.

1.Apricot trees can be sprayed, and the penitent faction mainly fights drugs to prevent Bihe and treat pests and diseases.

2.The common disease is apricot brown rot, it is recommended to spray 1:1:100 Bordeaux solution before germination, and spray 80% mancozeb 800 times immediately after flowering, and spray 75% chlorothalonil wettable powder 500-600 times at half-monthly intervals in the later stage.

3.In addition, attention should be paid to pest control. Envy Spine.

4.Apricot weevils and almond bees are common.

5.Spray the drug in a timely manner as well.

Apricot trees need to be pesticide-applied in the spring, before flowering, and plum trees need to be pesticide-applied before germination and after leaf-spreading.

1. Apricot trees: pesticides before flowering: spray branches with 5 Baumé stone sulfur mixture to prevent and control apricot scabs, black spots, ball kensuke and other overwintering insect eggs.

From mid-March to early April: timely spray 20% rapid culling 2000 times liquid and 50% carbendazim 600 times liquid mixture to prevent and control apricot weevil and apricot scab, black spot and perforation, and other insecticides and fungicides can also be mixed.

In mid-April, spraying 40% chrysanthemum emulsifiable concentrate 1000 times and Suclin 200 times liquid can prevent and treat apricot scab, black spot, perforation and peach aphid.

In mid-June, 2000-3000 times of the solution, 1000 times of the quick culling and 1500 times of the multi-mildew clear were used to control the insects and diseases of red spiders, mesophytes, black spot disease, perforation disease, etc., and the adults of the red-necked longhorn beetle were manually killed.

In mid to late July, the scaphoid caterpillars that are clustered but not dispersed are manually killed, or 2000 times of the liquid is sprayed in time to prevent and control the scaphoid caterpillars.

2. Plum tree.

Spray pesticides before plum germination and after leaf spread:

When plums bloom, you can spray copper succinate for preventive protection, which will better protect the flowers from damage.

Aphid occurrence period in early or mid-May every year: pesticide can be applied to the trunk to control insect pests, if the fruit is about to ripen, it is not possible to use pesticides directly, so it is necessary to control the use of pesticides 20 days before the fruit is ripe.

Pest control: spray 2500 times deltamethrin, apricot tree pest control is necessary to do maintenance, to spray pesticides in advance when the tree is healthy, when the apricot fruit is large in May, in order to effectively prevent insects, you can deploy 2500 times deltamethrin or kill inulin, for the larvae of the killing force is very large, the insecticidal effect is very good. Common insect pests of apricot trees include almond bees, canopy caterpillars, large green leafhoppers, red-necked beetles, etc., and effective control can ensure the growth of apricot trees.

Root rot: spray 200 times copper sulfate, root rot as the name suggests refers to the rot of plant roots, when the lateral roots and part of the taproot of the plant rot, the apricot tree will have dead leaves, you can spray 200 times copper sulfate agent to irrigate the roots, and before planting to disinfect in advance, and then after planting to carry out root irrigation prevention, so as not to lead to root rot.

During the flowering period of apricot trees, three thousandths of borax can be sprayed, which is conducive to fruit setting or cherry blossom setting of plants. Before flowering, you can spray Kao, and at the young fruit stage, you can spray Zhuangguo Tiling. Apricot trees grow most in deep, well-drained sandy soils, and apricot trees should be cultivated to ensure sufficient water and nutrients, and properly pruned to promote plant growth and flowering.

After the apricot tree falls flower, spraying 70 methyl tobuzin or 50 carbendazim 800 times solution can prevent and control apricot boils. After the apricot tree falls flower, spray 25 of 1500 times of larval urea, which can control leaf miner moth and leaf curly moth.

Expansion of the capital burying materials:

Note: When the new branches of the plant grow to about 15 cm is the best time for fertilization, it is best to fertilize the ground and the leaves at the same time, so as to maximize the effect of fertilizer. The second is to water the apricot tree after it has grown steadily, keep the soil moist, and irrigate the appropriate amount according to the moisture level of the soil.

Around May and June, it is necessary to prune the book, select a few branches with a good growth angle to retain, and erase all the rest, and often pluck the apricot tree to ensure the healthy growth of the plant.
