The timing of medication is not allowed
It is necessary to seize the opportunity to fight drugs. Only by understanding the law of the occurrence of pests and diseases , and using drugs at the right time can it work. For example, the treatment of aphids must be used at the peak of egg hatching. If you wait until the anthill has broken into the stalk, and there is a phenomenon of dryness, white spikes, dead spikes, etc., it is definitely not effective.
Improper application method
The occurrence of pests and diseases in the field and the habitat of pests have a harmful part on the crops. This particular site, this is what we use pesticides "Arrow" should be shot "target", not hit the target, pesticide control effect is poor. For example, the control of aphids is only directed at the rice heart leaf spray, the effect is good.
Increased resistance to cordyceps
The resistance of germs, pests and weeds to pesticides is a practical problem that hinders the full play of the pesticides' effective control effects and potential efficacy. With the rapid increase in the amount of pesticides and the continuous replacement of varieties, the resistance of pests and diseases is also increasing. Especially the main crops such as grain, oil, vegetables, tea and fruit are used frequently, and the resistance of pests and diseases is several times and dozens. Double the increase.
The target of prevention is not clear
It is common for diseases to be worms, insects to kill, and grass to be worms. This is first of all a diagnosis error, which is unclear and leads to wrong medication. For example, the red leaf blight that occurs after cotton buds, the veins turn green, the fleshy purple is red in pig liver, the leaves turn down, and eventually the coke falls off, people often mistakenly think that it is red spider. Soybean field weeds are harmful, causing soybean growth to stagnate, stunting, and some people often treat it as root knot nematode disease, etc., of course, the more severe the cure.
Spraying liquid waste is big
At present, the spray equipment commonly used in rural areas of China is still a worker-agricultural sprayer that has been consistently produced for decades. It is labor-intensive, wasteful, easy to poison, unsafe, coarse foggy, and poorly effective. According to the measurement, the spray method has poor adhesion and low deposition rate, and the liquid medicine is not only wasted, but the medicine droplets fall in the soil, are lost in the water, and seriously pollute the environment. Therefore, we should actively promote new tools and technologies such as low-volume spray, ultra-low-volume spray, mist, and electrostatic spray. This is an effective way to solve the problem of poor control and reduce pesticide waste.
Limitations of pesticides themselves
Some pesticides have certain pests and weeds good effect, but other pests can not do anything, poor control effect. For example, triazophos has better control effect on rice blast, cotton bollworm and other lepidopteran pests, and has obvious ovicidal effect. But it can stimulate the rice planthopper to lay eggs, causing the rice planthopper to smash again.
The application time is not well grasped
Diseases, insects and weeds have certain laws and have their own biological clocks. For example, cabbage butterfly, cabbage caterpillar adult, cotton leaf roller moth, rice blast, etc. all prefer to be active during daylight hours, while lepidoptera and some moths are active, mating and spawning at night. Therefore, only by mastering the law of the activity of pests, in the day, at different times, targeted "medication on time" can achieve the best control effect.
Weather conditions
The control effect of pesticides is related to different weather conditions. Different temperature, humidity, light, wind, and yin and other effects have an impact on the occurrence, activity and control effects of pests and diseases. If the temperature is below 8 °C, the herbicide is not easy to exert its efficacy; under the high temperature of 35 °C and strong illumination, the chemical pesticide is easy to evaporate and dissipate; the large liquid is easy to drift and blow, which also affects the control effect. Application of emulsifiable pesticides requires no rain for 24 hours when spraying; application of contact pesticides requires no rain for 48 hours.
Reduction of natural enemies
Due to the large-scale application of highly toxic, highly toxic and highly residual pesticides in the past years, the killing of pests has also killed the natural enemies of pests, which has destroyed the ecological balance and caused the pests to become more awkward and form a vicious circle.
Improper use of water quality
Water has hard water and soft water. Generally, well water, mine water, and spring water in some mountainous areas are mostly hard water. The effect of diluting pesticides is poor. Because this water contains minerals, it will decompose the active ingredients of pesticides. The pond water, river water and stream water are mostly soft water, the mineral content is small, and the effect of diluting pesticides is good. However, if the pond water and river water are very turbid, it will also affect the efficacy of the drug.

WHAT MAKE UP AN EXCELLENT LED GROW LIGHT ?
1.PPFD Value : PPFD is Photosynthetic Photon Flux Density. When you choose a plant light, you should compare the PPFD values of different plant lights. The larger the value, the better the growth of the plant.
2.Actual Power: Because the actual power of the plant light always varies with different conditions, all Amazon sellers use the rated power to describe the power of the product because the rated power is constant. When you pick a LED grow light, the rated power of the plant light is a reference, and more importantly is the actual power.
3.Core Coverage: In addition to the above two, when you choose a plant light, you also need to compare the cover area of different plant lights, of course, the size of the core coverage area. In general, in germination stage, you can hang the plant light higher and the cover area is larger. In flowering stage you can hang the plant light lower and the cover area is smaller because the plant needs more light at this stage. You have to compare different coverage areas to choose the plant light that suits you.
