Fertilizer pest effect is quite good
Use urea, ammonium bicarbonate, ammonia to kill insects
All three ammonia fertilizers have strong volatility and have irritating, corrosive and fumigating effects on pests. In particular, control effects are particularly good on spiders such as spider mites, leafhoppers, aphids, and thrips, which have small size and weak endurance. Such as using 2% urea solution, or 1% ammonium bicarbonate solution, or 0.5% ammonia solution, when the flower pests occur outside the root spray, spray every 7 days or so, even spray 2 or 3 times, pest control The effect is good.
Using phosphorus fertilizer to kill insects
Spraying cotton with 2% superphosphate solution can drive away spawning bollworms and kill cotton spider mites, cockroaches and other pests. Spraying tomato with 1% of superphosphate also has a significant effect on preventing umbilical rot.
Potash insecticide resistance
The most directly used in production to control pests and diseases of crops is that potash is a plant ash. Plant ash is a kind of high-quality potash fertilizer, but also contains nitrogen, calcium, magnesium, sulfur and various nutrient elements such as boron, manganese, copper, zinc, aluminum, etc.; it is soaked with 10kg of water and turf with 50kg of water and filtered for 24 hours, and the filtrate is sprayed. It can effectively kill locusts on crops; in the cotton seedling stage, 20-25 kg per mu of grass ash, and turfgrass spreading can increase the temperature of the soil and reduce the incidence of cotton blight, anthrax, and red rot.
Using silicon fertilizers to fight pests
When fertilizing the agricultural, forestry and flower crops, calcium-silicon fertilizer is mixed in. When the crops are absorbed, silicon will accumulate in the epidermis cells of the crops, forming a very hard epidermis layer, making it difficult for pests to invade, thus enhancing the resistance to pests.
Drugs and fertilizers mixed with insecticide
With 1% urea and 40% imidophos EC spray, you can kill red spider on cotton, flowers, and other pests. Use 3.8 kg of ammonium bicarbonate and 0.5 kg of copper sulphate powder that has been ground into a powder. Mix well and add 1 kg of lime to mix. Put it into a container or airtight plastic bag and close it for 24 hours. Shi, not only can prevent fungal and bacterial diseases, but also play the role of top dressing.
