Problems solved by technology
[0005] Now people try to prepare a variety of botanical pesticides to prevent and control plant diseases and insect pests, but there are common problems such as easy decomposition of active ingredients, limited duration of action, and short shelf life. Some people try to add white carbon black, light calcium, attapulgite Pesticide carriers such as soil and bentonite can be used to improve such problems, but most of the above-mentioned pesticide carriers have problems such as high surface acid value (pKa<1.8) and strong water absorption capacity (up to 15%), and the effect on pesticide promotion is not obvious

Abstract
The invention discloses a botanical pesticide special for tomatoes. The botanical pesticide is prepared from Chinese brake herb, fructus mume, milkvetch roots, tobacco leaves, folium isatidis, pomegranate seeds, flos rhododendri mollis, herb of sweetclover-like milkvetch, herba portulacae, modified attapulgite and modified diatomite. A traditional Chinese medicine extracting solution is compounded with the modified diatomite and attapulgite to be prepared into the finished pesticide product, all ingredients interact, a good curative effect on common early blight, late blight, powdery mildew, brown patch, blight, a root-knot nematode disease and the like of the tomatoes is achieved, the cure rate is up to 97% or above, relapse is not prone to occurrence, disease resistance cannot be caused, the stability of the pesticide is good, the beneficial ingredients are not prone to decomposition, the quality guarantee period can be prolonged to about three times, after the pesticide is applied, the growth characteristic of tomato plants is better improved, the content of lycopene in all the tomatoes is increased by 40% to 45%, the content of iodine and zinc elements is increased by 10%-20%, and good edibleness is achieved.
Description
technical field [0001] The invention belongs to the field of pesticides, and in particular relates to a special botanical pesticide for tomato.
