Management technology of drug use in peach trees for the whole year

In the first and middle of April, mite mites and peach aphids were controlled by fipronil and fipronil. In the middle and last ten days of April, the pear heart borer was controlled by applying isotropin. In the first ten days of May, Prochloraz Water Emulsion + Spirulina Ester + Lekuzole wettable Powder was used to control pear, peach aphid, peach scab, brown rot and so on. In the middle of May, Bordeaux liquid specially used for peach trees was used to control a variety of peach diseases. Around June 10: acetamiprid + avermectin + prochloraz water emulsion to control brown rot, pear heart borer and so on.

January and mid-April

1. Control objects: before peach trees sprout to blossom, they mainly control leaf mites and peach aphids.

2. Control measures: use 2500 times of 20% chlorphenazine and 4000-5000 times of fipronil for control. If there are weeds growing in the peach orchard between the rows, there is no need to add acaricidal agents. Because of the strong wind in spring, it is necessary to repeat spraying twice. During the period to avoid uneven spray, or can be sprayed when there is no wind at night.

February and late April

1. Control object: the pear heart borer is mainly controlled during the flowering period of peach trees.

2. Control measures: it can be applied to control pear heart borer, the uniform distribution is 60 points per mu, each point is 2g ointment, and the height is about 2m.

March and early May

1, control object: when petals fall off 80%, mainly control pear small, peach aphids, peach scab, brown rot and other diseases and insect pests.

2. Control measures: use 45% prochloraz water emulsion 1500 times, 22.4% snail ethyl ester 3000-4000 times, 20% chlorpromazole wettable powder 1000 times, or 3% Zhongshengmycin 500 times.

April and mid-May

The main results are as follows: 1. Control objects: in the calyx trouser period, mainly control a variety of peach diseases.

2. Prevention and control measures: use Bordeaux solution for peach trees, use water glass instead of lime in Bordeaux solution, blue alum ∶ water glass ∶ water ∶ 3.5% aged vinegar = 1 ∶ 8 ∶ 1000 ∶ 3, peach orchards with sufficient water resources, can spray water to rinse the residual nectar on young fruits, as well as sugar secreted by leaf nectaries, which is helpful to reduce bacterial infection, using about 1.6 tons of water per mu for each spray and washing 3-4 times before the rainy season.

Around May and June 10

1. Control objects: peach scab, brown rot, peach leaf moth, pear heart borer, peach red neck longicorn beetle and other diseases and insect pests.

2. Control measures: 20% acetamiprid 1500 times solution + 3.2% avermectin 3000-4000 times solution + 45% imipramine water emulsion 1500 times solution for control, sweet and sour solution to induce and kill longicorn beetles, the preparation ratio is sugar ∶ vinegar ∶ water = 50 ∶ 50 ∶ 400. late-maturing varieties need to cover pest-proof fruit bags.

June and mid-June

1. Control object: before wheat harvest, mainly control many kinds of diseases of peach trees.

2. Prevention and control measures: peach trees need to be pruned and thinned in summer to make peach trees ventilated and transparent. Bordeaux solution for peach trees can be used, blue alum ∶ water glass ∶ water = 1 ∶ 8 ∶ 1000, because peach trees are sensitive to copper, so after drying, do not spray repeatedly, need to spray for the second time at an interval of half a month, and should not be mixed with other pesticides and foliar fertilizers during this period.

July and early July

1. Control object: mainly control diseases and insect pests such as spider mite, two-spotted spider mite, pear heart borer, peach borer, etc.

2. Prevention and control measures: use 1500-2000 times solution of 25% triazol tin, 1000-2000 times solution of 5.7% methylvitamin salt and 600 times liquid of 4580% wettable powder of Dasheng.

August and mid-July

1. Control object: after early-maturing peach harvest, many kinds of diseases of peach trees are mainly controlled.

2. Control measures: use Bordeaux solution for peach trees, blue alum ∶ water glass ∶ water = 1 ∶ 8 ∶ 1000.

September, early to mid-August

1. Control object: mainly control pear small, peach borer, peach leaf moth, mulberry white scale and other diseases and insect pests.

2. Control measures: 1500 times of Amicida 25% suspension and 1500 times of acetamiprid can be used to control middle-ripe varieties after harvest, and dwarf oil sunflower and corn can be planted in advance to trap and kill peach borer.

October and late August

The main results are as follows: 1. Control object: when the top bud is formed on the new shoot of peach tree, the overwintering pests are mainly controlled.

2. Control measures: corrugated board or geotextile can be helped around the tree trunk, overwintering pests can be trapped and destroyed in winter, and base fertilizer can be applied in autumn, rotary tillage between rows can be cultivated, and overyear weeds can be sown, such as winter rape, orchid, Kentucky bluegrass, oatgrass, dwarf wheat, the Summer Solstice grass, zebra grass and so on.

November, early September

The main results are as follows: 1. Control object: when peach flower bud develops obviously, it mainly controls diseases and insect pests such as powdery mildew, pear small overwintering generation, big green leafhopper overwintering generation and so on.

2. Prevention and control measures: pruning is needed in autumn, which is beneficial to the ventilation and light transmission of peach trees. Light can be used to trap and kill adults of the leafhopper at night, and cut off the American white moth to form a net. In the initial stage, proper control generally does not need to use drugs.

December and mid-October

1. Control objects: before the return of peach aphids, they mainly control overwintering peach aphids, American white moths and so on.

2. Control measures: before and after Cold Dew belongs to the period of return of peach aphid, during which 4.5% cypermethrin can be sprayed 1000 times, which is beneficial to reduce the number of overwintering insects and control American white moth larvae at the same time.

13. Late October

The main results are as follows: 1. Control objects: 15 days before the defoliation of peach trees, mainly control the infection points of the fallen leaves and the residual pathogens.

2. Control measures: use Baume 3-5 degree stone sulfur mixture, or Bordeaux solution for peach trees, blue alum ∶ water glass ∶ water = 2 ∶ 8 ∶ 1000.
