Green vegetables and insects, do not want to buy pesticides to prevent insects? Over the past thousands of years, the rural areas have accumulated countless insect control experience, which can be applied to pollution-free vegetables, green vegetables and organic vegetables to control insect pests, and is also suitable for balconies, roofs and courtyard small vegetable gardens of the balcony family. Common pests of green vegetables include grubs, ditch needle worms, moths, small ground tigers, aphids, small cabbage moths, vegetable green worms, vegetable borers, yellow curved stripe jumping nails, etc., which can reduce the insect population base through non-pesticide means.
1. Biological control methods such as insect treatment can reduce the pest base, ensure vegetable quality and avoid pesticide residues.
1.1 Natural enemies such as broad-eyed bees, red velvet cocoon bees, and phoenix butterflies can be taken to control and control vegetable green insects. You can also catch 20 vegetable green worm larvae alive, add 3 kg of water after mashing, and then add 20 grams of laundry detergent for spraying, which can effectively eliminate the vegetable green worm.
1.2 Spray with 500-800 times of Bacillus thuringiensis milk on green vegetables to control green worms and borers.
1.3 It can protect or release aphids in the field such as seven-star ladybirds, multi-heterogeneous ladybirds, grasshoppers, aphid-eating flies, ding-striped leopard spiders, and black-eating aphid blind aphids.
2. The use of plants processed into insecticides can quickly kill pests.
2.1 Spreading grass and wood ash on the leaves of green cabbage can significantly reduce the harm of aphids and can reduce the spawning volume of pests such as cabbage worms, cabbage moths and vegetable borers.
2.2 Soak the cigarette stick and tobacco for 3-5 days, add a little washing powder, spray on the green vegetables, you can kill aphids, small cabbage moths, vegetable borers, vegetable green worms and small cabbage moths and other larvae.
2.3 You can use 1 kg of dried peppers, add 10 kg of water, cook for half an hour, take the clarification solution and spray, control aphids and green worms and other special effects. Garlic and red pepper can also be mixed in a 1:1 ratio, and the juice can be extracted and sprayed with water to effectively control vegetable insects.
2.4 Boiling water with neem leaves and spraying on green vegetables can effectively kill most pests.
2.5 You can use 1 kg of water plus 2.4 kg of cucumber vine after mashing the juice, add 12 kg of water to spray the leaves to control the vegetable borer and the green worm. It can also be used to control vegetable borers and green worms with uniform sprays such as 2.5% rotenone emulsion 1000 times liquid and 0.36% matrine emulsion 1000 times liquid.
2.6 After the castor leaves are crushed into powder, they are sprayed according to the ratio of 1:20 plus water, which has the effect of repelling insects and insects on grubs, caddisflies, vegetable borers and caddisflies.
3. Use urea, washing powder, wind oil essence and other pests to control pests, but also play a role in foliar spraying fertilizer.
3.1 Use 100 g of water, add 3-4 g of laundry detergent, and spray 2-3 times foliar to quickly kill aphids.
3.2 The urea, washing powder and water are prepared in the ratio of 4:1:100, and the foliar spray can supplement urea, kill aphids, and reduce the harm of green insects.
3.3 Spray after adding 600-800 times of water with "wind oil essence", and the aphids will die quickly after contact.
4. Use black light and sticky worm board to eliminate pests.
The armyworm board can be used to lure adult lepidoptera such as cabbage worms, cabbage moths and vegetable borers to reduce the pest base.
Taking advantage of the light-oriented nature of pests and setting up lights such as black lights to trap them, most lepidoptera adults can be eliminated.
5. Artificial insecticide.
5.1 You can use a brush and other dipping water to carefully brush off the leaves and stems of aphids, lepidoptera larvae and egg blocks, and concentrate on destruction.
5.2 Every morning after the dew has dried, catch the larvae and eggs of the cabbage worms, small cabbage moths and vegetable borers on the front and back of the leaves.
6. Agricultural prevention and control.
6.1 Remove plants with severe insect damage from larger densities and remove leaves that are seriously harmful.
6.2 Clean the countryside, eradicate weeds in and around the field, and reduce the base of insect sources such as aphids.
6.3 Deep ploughing of the soil before sowing, using high temperature, low temperature and natural enemies to eliminate egg masses, larvae, pupae and adult insects in some soils.
6.4 Avoid continuous cropping with cruciferous vegetables to reduce the insect population base.
6.5 Adjust the sowing period appropriately and avoid sowing seeds during the high incidence of pests.
In fact, only chemical pesticides control pests are the most thorough, want not to apply pesticides, need to spend a lot of manpower, but the biggest benefit is that there is no pesticide pollution, eat safe. Therefore, most of the family's small vegetable gardens do not use pesticides, although the control is not thorough, there will be many small insect eyes, which is very popular with consumers in the market.
