spraying drone agriculture for corn application

Verification of corn plant protection by EAVISION drone sprayer, high control effect and low economic loss

Oct 12 , 2022

Maize is a high-yield crop, but due to the influence of pests and weeds, it once caused a loss of yield. Therefore, in the process of corn planting and management, the most urgent thing is to recover the losses and increase the yield. The bell-mouth stage and the tasseling stage are the key periods to protect the three leaves of the cob. Only by fully contacting the three leaves of the corn cob with the chemicals and protecting the function of the leaves can the advantages of the variety be exerted and the ear of the corn be fully filled. At the same time, it can also achieve "live rod maturity" in order to recover losses and achieve high yields.

If corn is to be high in yield, the protection of clover leaves is the key

The total leaf area of the three leaves can reach 30-40% of the total leaf area, and the contribution rate to the grain growth can exceed 60%. The impact of each leaf on the yield of the three leaves is 2 times more. The chlorophyll is the most, the leaves are the longest, the widest and the thickest, and the activity of enzymes in the three leaves is also the strongest compared with other leaves.

It has been verified by experiments that the utilization rate of drone sprayer flight control agents is as follows

Other Drones

Pharmacy evaporation loss 10-30%

Pharmacy fusion drops 20-25%

Pharmacy reaches top 40-55%

The medicine is served with less stick trefoil

EAVISION Drone Sprayer

Very little loss of agrochemical

Pharmacy reaches top 20-30%

More than 60% of the medicine delivered to the stick clover

*The room temperature mist spray system of EAVISION drone perfectly cooperates with the wind field, and has strong penetration. The precise spray can accurately deliver the liquid medicine to all parts of the plant, effectively reducing the waste of agrochemical and improving the effect of plant protection.

EAVISION Drone Sprayer Control of Pests and Diseases in Corn Flare Stage

Corn growing period: bell mouth period Spraying time: July 20, 2021

Control objects: corn diseases and insect pests (Lepidoptera pests, corn leaf spot, etc.)

Test site: Zhaoyuan City, Shandong Province

Model EAVISION: EA-20X

Flight speed (m) 5.5

Spray width (m): 3

Atomization level (micron): 40

Flight altitude (m): 1.8

Water consumption (liter/acre): 1.5

Content	Spraying machinery	Agrochemical	dosage of formulation	Active ingredient dosage
A	EA-20X	200 g/L tetrazolium amide suspension agent 30% oxime bacteria tebuconazole suspension agent 70% Prosenzinc WP	5 20 50	1 6 25
B	EA-20X	200 g/L tetrazolium amide suspension agent 30% oxime bacteria tebuconazole suspension agent 70% Prosenzinc WP	10 40 100	2 12 70
CK	local routine
Note: group A is the half dose, group B is the normal dose

The front and back sides of the leaves and the core of the plant are uniformly applied to the control target, which improves the control effect of diseases and insect pests. The conventional plan recovered an average of 5-15% of the loss, the A treatment recovered 8.46% of the loss, and the B treatment recovered 15.99% of the loss.

Note: Please plan the control plan reasonably according to the actual situation of pests and weeds to achieve the best effect.

Note: The dosage of treatment B and treatment D is the registered dosage of the manufacturer, and the dosage of treatment A and treatment C is half of the registered dosage of the manufacturer

Note: Please plan the control plan reasonably according to the actual situation of pests and weeds to achieve the best effect.

EAVISION drone sprayer: The upper, middle and lower parts of the water-sensitive paper are all distributed, and the droplets are uniform, and there is no large particle drug spot.

Other drones: the water-sensitive paper in the middle and lower parts has no feedback, and the water-sensitive paper in the upper part has droplet feedback, all of which are large particles.

Test Results

Content	Yield (kg/acre)	Recover damages(%)
A	823.3	14
B	852	17.97
C	801.5	10.98
D	830.8	15.04
E	722.2	-

EAVISION plant protection drones control pests and diseases, the highest control effect is 93.65%, and the protection and recovery of corn loss is as high as 17.97%. The high dose of other drone sprayers is equivalent to the low dose of EAVISION drone sprayer (halving the dose) to recover the yield loss. This test proves that the EAVISION drone sprayer can save about 50% of the drug during the corn plant protection.
